I completed an initial version of the Chambers Library map for the Books and Borrowing project this week. It took quite a lot of time and effort to implement the subscription period range slider. Searching for a range when the data also has a range of dates rather than a single date means we needed to make a decision about what data gets returned and what doesn’t. This is because the two ranges (the one chosen as a filter by the user and the one denoting the start and end periods of subscription for each borrower) can overlap in many different ways. For example, the period chosen by the user is 05 1828 to 06 1829. Which of the following borrowers should therefore be returned?
- Borrowers range is 06 1828 to 02 1829: Borrower’s range is fully within the period so should definitely be included
- Borrowers range is 01 1828 to 07 1828: Borrower’s range extends beyond the selected period at the start and ends within the selected period. Presumably should be included.
- Borrowers range is 01 1828 to 09 1829: Borrower’s range extends beyond the selected period in both directions. Presumably should be included.
- Borrowers range is 05 1829 to 09 1829: Borrower’s range begins during the selected period and ends beyond the selected period. Presumably should be included.
- Borrowers range is 01 1828 to 04 1828: Borrower’s range is entirely before the selected period. Should not be included
- Borrowers range is 07 1829 to 10 1829: Borrower’s range is entirely after the selected period. Should not be included.
Basically if there is any overlap between the selected period and the borrower’s subscription period the borrower will be returned. But this means most borrowers will always be returned a lot of the time. It’s a very different sort of filter to one that purely focuses on a single date – e.g. filtering the data to only those borrowers whose subscription periods *begins* between 05 1828 and 06 1829.
Based on the above assumptions I began to write the logic that would decide which borrowers to include when the range slider is altered. It was further complicated by having to deal with months as well as years. Here’s the logic in full if you fancy getting a headache:
if(((mapData[i].sYear>startYear || (mapData[i].sYear==startYear && mapData[i].sMonth>=startMonth)) && ((mapData[i].eYear==endYear && mapData[i].eMonth <=endMonth) || mapData[i].eYear<endYear)) || ((mapData[i].sYear<startYear ||(mapData[i].sYear==startYear && mapData[i].sMonth<=startMonth)) && ((mapData[i].eYear==endYear && mapData[i].eMonth >=endMonth) || mapData[i].eYear>endYear)) || ((mapData[i].sYear==startYear && mapData[i].sMonth<=startMonth || mapData[i].sYear>startYear) && ((mapData[i].eYear==endYear && mapData[i].eMonth <=endMonth) || mapData[i].eYear<endYear) && ((mapData[i].eYear==startYear && mapData[i].eMonth >=startMonth) || mapData[i].eYear>startYear)) || (((mapData[i].sYear==startYear && mapData[i].sMonth>=startMonth) || mapData[i].sYear>startYear) && ((mapData[i].sYear==endYear && mapData[i].sMonth <=endMonth) || mapData[i].sYear<endYear) && ((mapData[i].eYear==endYear && mapData[i].eMonth >=endMonth) || mapData[i].eYear>endYear)) || ((mapData[i].sYear<startYear ||(mapData[i].sYear==startYear && mapData[i].sMonth<=startMonth)) && ((mapData[i].eYear==startYear && mapData[i].eMonth >=startMonth) || mapData[i].eYear>startYear)))
I also added the subscription period to the popups. The only downside to the range slider is that the occupation marker colours change depending on how many occupations are present during a period, so you can’t always tell an occupation by its colour. I might see if I can fix the colours in place, but it might not be possible.
I also noticed that the jQuery UI sliders weren’t working very well on touchscreens so installed the jQuery TouchPunch library to fix that (https://github.com/furf/jquery-ui-touch-punch). I also made the library marker bigger and gave it a white border to more easily differentiate it from the borrower markers.
I then moved onto incorporating page images in the resource too. Where a borrower has borrower records the relevant pages where these borrowing records are found now appear as thumbnails in the borrower popup. These are generated by the IIIF server based on dimensions passed to it, which is much nicer than having to generate and store thumbnails directly. I also updated the popup to make it wider when required to give more space for the thumbnails. Here’s a screenshot of the new thumbnails in action:
Clicking on a thumbnail opens a further popup containing a zoomable / pannable image of the page. This proved to be rather tricky to implement. Initially I was going to open a popup in the page (outside of the map container) using a jQuery UI Dialog. However, I realised that this wouldn’t work when the map was being viewed in full-screen mode, as nothing beyond the map container is visible in such circumstances. I then considered opening the image in the borrower popup but this wasn’t really big enough. I then wondered about extending the ‘Map options’ section and replacing the contents of this with the image, but this then caused issues for the contents of the ‘Map options’ section, which didn’t reinitialise properly when the contents were reinstated. I then found a plugin for the Leaflet mapping library that provides a popup within the map interface (https://github.com/w8r/Leaflet.Modal) and decided to use this. However, it’s all a little complex as the popup then has to include another mapping library called OpenLayers that enables the zooming and panning of the page image, all within the framework of the overall interactive map. It is all working and I think it works pretty well, although I guess the map interface is a little cluttered, what with the ‘Map Options’ section, the map legend, the borrower popup and then the page image popup as well. Here’s a screenshot with the page image open:
All that’s left to do now is add in the introductory text once Alex has prepared it and then make the map live. We might need to rearrange the site’s menu to add in a link to the Chambers Map as it’s already a bit cluttered.
Also for the project I downloaded images for two further library registers for St Andrews that had previously been missed. However, there are already records for the registers and pages in the CMS so we’re going to have to figure out a way to work out which image corresponds to which page in the CMS. One register has a different number of pages in the CMS compared to the image files so we need to work out how to align the start and end and if there are any gaps or issues in the middle. The other register is more complicated because the images are double pages whereas it looks like the page records in the CMS are for individual pages. I’m not sure how best to handle this. I could either try and batch process the images to chop them up or batch process the page records to join them together. I’ll need to discuss this further with Gerry, who is dealing with the data for St Andrews.
Also this week I prepared for and gave a talk to a group of students from Michigan State University who were learning about digital humanities. I talked to them for about an hour about a number of projects, such as the Burns Supper map (https://burnsc21.glasgow.ac.uk/supper-map/), the digital edition I’d created for New Modernist Editing (https://nme-digital-ode.glasgow.ac.uk/), the Historical Thesaurus (https://ht.ac.uk/), Books and Borrowing (https://borrowing.stir.ac.uk/) and TheGlasgowStory (https://theglasgowstory.com/). It went pretty and it was nice to be able to talk about some of the projects I’ve been involved with for a change.
I also made some further tweaks to the Gentle Shepherd Performances page which is now ready to launch, and helped Geert out with a few changes to the WordPress pages of the Anglo-Norman Dictionary. I also made a few tweaks to the WordPress pages of the DSL website and finally managed to get a hotel room booked for the DHC conference in Sheffield in September. I also made a couple of changes to the new Gaelic Tongues section of the Seeing Speech website and had a discussion with Eleanor about the filters for Speech Star. Fraser had been in touch with about 500 Historical Thesaurus categories that had been newly matched to OED categories so I created a little script to add these connections to the online database.
I also had a Zoom call with the Speak For Yersel team. They had been testing out the resource at secondary schools in the North East and have come away with lots of suggested changes to the content and structure of the resource. We discussed all of these and agreed that I would work on implementing the changes the week after next.
Next week I’m going to be on holiday, which I have to say I’m quite looking forward to.
I worked for several different projects this week. For the Books and Borrowing project I processed and imported a further register for the Advocates library that had been digitised by the NLS. I also continued with the interactive map of Chambers library borrowers, although I couldn’t spend as much time on this as I’d hoped as my access to Stirling University’s VPN had stopped working and without VPN access I can’t connect to the database and the project server. It took a while to resolve the issue as access needs to be approved by some manager or other, but once it was sorted I got to work on some updates.
One thing I’d noticed last week was that when zooming and panning the historical map layer was throwing out hundreds of 403 Forbidden errors to the browser console. This was not having any impact on the user experience, but was still a bit messy and I wanted to get to the bottom of the issue. I had a very helpful (as always) chat with Chris Fleet at NLS Maps, who provided the historical map layer and he reckoned it was because the historical map only covers a certain area and moving beyond this was still sending requests for map tiles that didn’t exist. Thankfully an option exists in Leaflet that allows you to set the boundaries for a map layer (https://leafletjs.com/reference.html#latlngbounds) and I updated the code to do just that, which seems to have stopped the errors.
I then returned to the occupations categorisation, which was including far too many options. I therefore streamlined the occupations, displaying the top-level occupation only. I think this works a lot better (although I need to change the icon colour for ‘unknown’). Full occupation information is still available for each borrower via the popup.
I also had to change the range slider for opacity as standard HTML range sliders don’t allow for double-ended ranges. We require a double-ended range for the subscription period and I didn’t want to have two range sliders that looked different on one page. I therefore switched to a range slider offered by the jQuery UI interface library (https://jqueryui.com/slider/#range). The opacity slider still works as before, it just looks a little different. Actually, it works better than before, as the opacity now changes as you slide rather than only updating after you mouse-up.
I then began to implement the subscription period slider. This does not yet update the data. It’s been pretty tricky to implement this. The range needs to be dynamically generated based on the earliest and latest dates in the data, and dates are both year and month, which need to be converted into plain integers for the slider and then reinterpreted as years and months when the user updates the end positions. I think I’ve got this working as it should, though. When you update the ends of the slider the text above that lists the months and years updates to reflect this. The next step will be to actually filter the data based on the chosen period. Here’s a screenshot of the map featuring data categorised by the new streamlined occupations and the new sliders displayed:
For the Speak For Yersel project I made a number of tweaks to the resource, which Jennifer and Mary are piloting with school children in the North East this week. I added in a new grammatical question and seven grammatical quiz questions. I tweaked the homepage text and updated the structure of questions 27-29 of the ‘sound about right’ activity. I ensured that ‘Dumfries’ always appears as ‘Dumfries and Galloway’ in the ‘clever’ activity and follow-on and updated the ‘clever’ activity to remove the stereotype questions. These were the ones where users had to rate the speakers from a region without first listening to any audio clips and Jennifer reckoned these were taking too long to complete. I also updated the ‘clever’ follow-on to hide the stereotype options and switched the order of the listener and speaker options in the other follow-on activity for this type.
For the Speech Star project I replaced the data for the child speech error database with a new, expanded dataset and added in ‘Speaker Code’ as a filter option. I also replicated the child speech and normalised speech databases from the clinical website we’re creating on the more academic teaching site we’re creating and also pulled in the IPA chart from Seeing Speech into this resource too. Here’s a screenshot of how the child speech error database looks with the new ‘speaker code’ filter with ‘vowel disorder’ selected:
I also made a couple of tweaks to the DSL this week, installing the TablePress plugin for the ancillary pages and creating a further alternative logo for the DSL’s Facebook posts. I also returned to going some work for the Anglo-Norman Dictionary, offering some advice to the editor Geert about incorporating publications and overhauling how cross references are displayed in the Dictionary Management System.
I updated the ‘View Entry’ page in the DMS. Previously it only included cross references FROM the entry you’re looking at TO any other entries. I.e. it only displayed content when the entry was of type ‘xref’ rather than ‘main’. Now in addition to this there’s a further section listing all cross references TO the entry you’re looking at from any entry of type ‘xref’ that links to it.
In addition there is a button allowing you to view all entries that include a cross reference to the current entry anywhere in their XML – i.e. where an <xref> tag that features the current entry’s slug is found at any level in any other main entry’s XML. This code is hugely memory intensive to run, as basically all 27,464 main entries need to be pulled into the script, with the full XML contents of each checked for matching xrefs. For this reason the page doesn’t run the code each time the ‘view entry’ page is loaded but instead only runs when you actively press the button. It takes a few seconds for the script to process, but after it does the cross references are listed in the same manner as the ‘pure’ xrefs in the preceding sections.
Finally I participated in a Zoom-based focus group for the AHRC about the role of technicians in research projects this week. It was great to participate to share my views on my role and to hear from other people with similar roles at other organisations.
I’d taken Monday off this week to have an extra-long weekend following the jubilee holidays on Thursday and Friday last week. On Tuesday I returned to another meeting for Speak For Yersel and a list of further tweaks to the site, including many changes to three of the five activities and a new set of colours for the map marker icons, which make the markers much more easy to differentiate.
I spent most of the week working on the Books and Borrowing project. We’d been sent a new library register from the NLS and I spent a bit of time downloading the 700 or so images, processing them and uploading them into our system. As usual, page numbers go a bit weird. Page 632 is written as 634 and then after page 669 comes not 670 but 700! I ran my script to bring the page numbers in the system into line with the oddities of the written numbers. On Friday I downloaded a further library register which I’ll need to process next week.
My main focus for the project was the Chambers Library interactive map sub-site. The map features the John Ainslie 1804 map from the NLS, and currently it uses the same modern map as I’ve used elsewhere in the front-end for consistency, although this may change. The map defaults to having a ‘Map options’ pane open on the left, and you can open and close this using the button above it. I also added a ‘Full screen’ button beneath the zoom buttons in the bottom right. I also added this to the other maps in the front-end too. Borrower markers have a ‘person’ icon and the library itself has the ‘open book’ icon as found on other maps.
By default the data is categorised by borrower gender, with somewhat stereotypical (but possibly helpful) blue and pink colours differentiating the two. There is one borrower with an ‘unknown’ gender and this is set to green. The map legend in the top right allows you to turn on and off specific data groups. The screenshot below shows this categorisation:
The next categorisation option is occupation, and this has some problems. The first is there are almost 30 different occupations, meaning the legend is awfully long and so many different marker colours are needed that some of them are difficult to differentiate. Secondly, most occupations only have a handful of people. Thirdly, some people have multiple occupations, and if so these are treated as one long occupation, so we have both ‘Independent Means > Gentleman’ and then ‘Independent Means > Gentleman, Politics/Office Holders > MP (Britain)’. It would be tricky to separate these out as the marker would then need to belong to two sets with two colours, plus what happens if you hide one set? I wonder if we should just use the top-level categorisation for the groupings instead? This would result in 12 groupings plus ‘unknown’, meaning the legend would be both shorter and narrower. Below is a screenshot of the occupation categorisation as it currently stands:
The next categorisation is subscription type, which I don’t think needs any explanation. I then decided to add in a further categorisation for number of borrowings, which wasn’t originally discussed but as I used the page I found myself looking for an option to see who borrowed the most, or didn’t borrow anything. I added the following groupings, but these may change: 0, 1-10, 11-20, 21-50, 51-70, 70+ and have used a sequential colour scale (darker = more borrowings). We might want to tweak this, though, as some of the colours are a bit too similar. I haven’t added in the filter to select subscription period yet, but will look into this next week.
At the bottom of the map options is a facility to change the opacity of the historical map so you can see the modern street layout. This is handy for example for figuring out why there is a cluster of markers in a field where ‘Ainslie Place’ was presumably built after the historical map was produced.
I decided to not include the marker clustering option in this map for now as clustering would make it more difficult to analyse the categorisation as markers from multiple groupings would end up clustered together and lose their individual colours until the cluster is split. Marker hover-overs display the borrower name and the pop-ups contain information about the borrower. I still need to add in the borrowing period data, and also figure out how best to link out to information about the borrowings or page images. The Chambers Library pin displays the same information as found in the ‘libraries’ page you’ve previously seen.
Also this week I responded to a couple of queries from the DSL people about Google Analytics and the icons that gets used for the site when posting on Facebook. Facebook was picking out the University of Glasgow logo rather than the DSL one, which wasn’t ideal. Apparently there’s a ‘meta’ tag that you need to add to the site header in order for Facebook to pick up the correct logo, as discussed here: https://stackoverflow.com/questions/7836753/how-to-customize-the-icon-displayed-on-facebook-when-posting-a-url-onto-wall
I also created a new user for the Ayr place-names project and dealt with a couple of minor issues with the CMS that Simon Taylor had encountered. I also investigated a certificate error with the ohos.ac.uk website and responded to a query about QR codes from fellow developer David Wilson. Also, Craig Lamont in Scottish Literature got in touch about a spreadsheet listed Burns manuscripts that he’s been working on with a view to turning it into a searchable online resource and I gave him some feedback about the structure of the spreadsheet.
Finally, I did a bit of work for the Historical Thesaurus, working on a further script to match up HT and OED categories based on suggestions by researcher Beth Beattie. I found a script I’d produced in from 2018 that ran pattern matching on headings and I adapted this to only look at subcats within 02.02 and 02.03, picking out all unmatched OED subcats from these (there are 627) and then finding all unmatched HT categories where our ‘t’ numbers match the OED path. Previously the script used the HT oedmaincat column to link up OED and HT but this no longer matches (e.g. HT ‘smarten up’ has ‘t’ nums 02.02.16.02 which matches OED 02.02.16.02 ‘to smarten up’ whereas HT ‘oedmaincat’ is ’02.04.05.02’).
The script lists the various pattern matches at the top of the page and the output is displayed in a table that can be copied and pasted into Excel. Of the 627 OED subcats there are 528 that match an HT category. However, some of them potentially match multiple HT categories. These appear in red while one to one matches appear in green. Some of these multiple matches are due to Levenshtein matches (e.g. ‘sadism’ and ‘sadist’) but most are due to there being multiple subcats at different levels with the exact same heading. These can be manually tweaked in Excel and then I could run the updated spreadsheet through a script to insert the connections. We also had an HT team meeting this week that I attended.
It was a three-day week as Thursday and Friday were bank holidays for the Queen’s Platinum Jubilee. I spent most of the available time working on the Books and Borrowers project. I had a chat with RA Alex Deans about the data for the Chambers Library sub-project that we’re hoping to launch in July. Although this data is already in the system it needs additional latitude and longitude data so we can position borrowers on an interactive map. We decided to add this data and some other data using the ‘additional fields’ system in the CMS and Alex is hopefully going to get this done by next week.
I’d made a start on the API for the project last week, and this week I completed the endpoint that displays all of the data that will be needed for the ‘Browse Libraries’ page, which can be accessed as JSON or CSV data. This includes counts of registers, borrowing records, books and borrowers plus a breakdown of the number of borrowings per year at each library that will be used for the stacked column chart. The systems reside on servers at Stirling University, and their setup has the database on a different server to the code. This means there is an overhead when sending queries to the database as each one needs to be sent as an HTTP request rather than dealt with locally. This has led me to be a bit more efficient when constructing queries. For example, rather than running individual ‘count’ queries for each library after running an initial query to retrieve all library details I’ve instead used subqueries as part of the initial query so all the data including the counts gets processed and returned by the database via one HTTP request.
With the data retrieval aspects of the ‘browse libraries’ page completed I then moved on to developing the page itself. It has an introductory section (with placeholder text for now) then a map showing the locations of the libraries. Any libraries that currently have lat/lng data appear on this map. The markers are clustered when zoomed out, with the number referring to the number of libraries in the cluster. I selected a map design that I thought fitted in with the site, but this might change, and I used an open book icon for the library map marker on a red background (to match the site’s header text colour) and again this may change. You can hover over a marker to see the library name and press on a marker to open a popup containing a link to the library, the library name and alternative names, location, foundation date, type and statistics about registers, books, borrowers and records.
Beneath the map is a tabular view of the data. This is the exact same data as is found on the map. Library names are buttons leading to the library’s page. You can change the order of the table by pressing on a heading (e.g. to see which library has the most books). Pressing a second time reverses the order. Below is a screenshot showing the map and the table, with the table ordered by number of borrowing records:
There are a couple of things I could do to make this more legible if required. Firstly, we could use a stacked bar chart instead (https://www.highcharts.com/demo/bar-stacked). The years would then be on the y-axis and we could have a very long chart with all of the years in place rather than aggregating to decades. This would make it more difficult to view the legend and the x-axis tick marks, as you would need to scroll down to see them. Secondly, we could stick with the decade view but then give the user the option of selecting a decade to view a new chart featuring the individual years in that decade. This would make it harder for users to get the big picture all at once, although I guess the decade view would give that.
Also this week I checked up on the Speak For Yersel website, as we had sent the URL out to people with an interest in the Scots language at the end of last week. When I checked on Wednesday we’d had 168 registered users. These users had submitted 8,110 answers for the main questions plus 85 for the ‘drag onto map’ and 85 for the transcript. 606 of those main answers are from people who have chosen ‘outside Scotland’. I also realised that I’d set the markers to be smaller if there were more than 100 answers on a map but the markers looked too small so I’ve updated things to make them the same size no matter how many answers there are.
My other main task for the week was to finalise the transfer of the Uist Saints website. We managed to get the domain name ownership transferred over to Glasgow and paid the subscription fee for the next nine years and the version of the site hosted at Glasgow can now be found here: https://uistsaints.co.uk/
I’d completed all of the outstanding tasks for ‘Speak For Yersel’ last week so this week I turned my attention to several other projects. For the Books and Borrowing project I wrote a script to strip out duplicate author records from the data and reassign any books associated with the duplicates to the genuine author records. The script iterated through each author in the ‘duplicates’ spreadsheet, found all rows where the ‘AID’ did not match the ‘AID to keep’ column, reassigned any book author records from the former to the latter and then deleted the author record. The script deleted 310 duplicate authors and reassigned 735 books to other authors, making the data in the content management system a lot cleaner.
I then moved on to the Ramsay ‘Gentle Shepherd’ data, and this week tackled the issue of importing the code I’d written into the University website’s T4 content management system. I created a ‘one file’ version of the page that has everything incorporated in one single file – all the scripts, the data and the styles. I was hoping I’d then be able to just upload this to T4 but I ran into a problem:
A helpful guy called Rick in the Web Team suggested using the ‘standard’ content type and T4’s way of linking to files to get things working, and this did sort of work, but while the ‘standard’ content type allows you to manually edit the HTML, T4 then processes any HTML you enter, which included stripping out a lot of tags my code needed and overwriting other HTML tags, which was very frustrating.
However, I was able to view the source for the embedded media files in this template and then copy this into my ‘standard plain’ section and this seems to have worked. There were other issues, though, such as that T4 applies its CSS styles AFTER any locally created styles meaning a lot of my custom styles were being overwritten. I managed to find a way around this and the section of the page is now working if you preview it in T4.
With all of this out of the way I was hoping to begin work on the API and front-end for the Books and Borrowing project, and I did manage to make a start on this. However, many further tweaks and updates came through from Jennifer Smith for the Speak For Yersel system, which we’re intending to sent out to selected people next week, and I ended up spending most of the rest of the week on this project instead. This included several Zoom calls and implementing countless minor tweaks to the website content, including homepage text, updating quiz questions and answer options, help text, summary text, replacing images, changing styles and other such things. I also updated the maps to set their height dynamically based on the height of the browser window, ensuring that the map and the button beneath it are visible without scrolling (but also including a minimum height so the map never gets too small). I also made the maps wider and the question area narrower as there was previously quite a lot of wasted space with there was a 50/50 split between the two.
I also fixed a bug with the slider-based questions that was only affecting Safari that prevented the ‘next’ button from activating. This was because the code that listened for the slider changing was set to do something when a slider was clicked on, but for it to work in Safari instead of ‘click’ the event needed to be ‘change’. I also added in the new dictionary-based question type and added in the questions, although we then took these out again for now as we’d promised the DSL that the embedded school dictionary would only be used by the school children in our pilot. I also added in a question about whether the user has been to university to the registration page and then cleared out all of the sample data and users that we’d created during our testing before actual users begin using the resource next week.
This week I finished off all of the outstanding work for the Speak For Yerself project. The other members of the team (Jennifer and Mary) are both on holiday so I finished off all of the tasks I had on my ‘to do’ list, although there will certainly be more to do once they are both back at work again. The tasks I completed were a mixture of small tweaks and larger implementations. I made tweaks to the ‘About’ page text and changed the intro text to the ‘more give your word’ exercise. I then updated the age maps for this exercise, which proved to be pretty tricky and time-consuming to implement as I needed to pull apart a lot of the existing code. Previously these maps showed ‘60+’ and ‘under 19’ data for a question, with different colour markers for each age group showing those who would say a term (e.g. ‘Scunnered’) and grey markers for each age group showing those who didn’t say the term. We have completely changed the approach now. The maps now default to showing ‘under 19’ data only, with different colours for each different term. There is now an option in the map legend to switch to viewing the ‘60+’ data instead. I added in the text ‘press to view’ to try and make it clearer that you can change the map. Here’s a screenshot:
I also updated the ‘give your word’ follow-on questions so that they are now rated in a new final page that works the same way as the main quiz. In the main ‘give your word’ exercise I updated the quiz intro text and I ensured that the ‘darker dots’ explanatory text has now been removed for all maps. I tweaked a few questions to change their text or the number of answers that are selectable and I changed the ‘sounds about right’ follow-on ‘rule’ text and made all of the ‘rule’ words lower case. I also made it so that when the user presses ‘check answers’ for this exercise a score is displayed to the right and the user is able to proceed directly to the next section without having to correct their answers. They still can correct their answers if they want.
I then made some changes to the ‘She sounds really clever’ follow-on. The index for this is now split into two sections, one for ‘stereotype’ data and one for ‘rating speaker’ data and you can view the speaker and speaker/listener results for both types of data. I added in the option of having different explanatory text for each of the four perception pages (or maybe just two – one for stereotype data, one for speaker ratings) and when viewing the speaker rating data the speaker sound clips now appear beneath the map. When viewing the speaker rating data the titles above the sliders are slightly different. Currently when selecting the ‘speaker’ view the title is “This speaker from X sounds…” as opposed to “People from X sound…”. When selecting the ‘speaker/listener’ view the title is “People from Y think this speaker from X sounds…” as opposed to “People from Y think people from X sound…”. I also added a ‘back’ button to these perception follow-on pages so it’s easier to choose a different page. Finally, I added some missing HTML <title> tags to pages (e.g. ‘Register’ and ‘Privacy’) and fixed a bug whereby the ‘explore more’ map sound clips weren’t working.
With my ‘Speak For Yersel’ tasks out of the way I could spend some time looking at other projects that I’d put on hold for a while. A while back Eleanor Lawson contacted me about adding a new section to the Seeing Speech website where Gaelic speaker videos and data will be accessible, and I completed a first version this week. I replicated the Speech Star layout rather than the /r/ & /l/ page layout as it seemed more suitable: the latter only really works for a limited number of records while the former works well with lots more (there are about 150 Gaelic records). What this means is the data has a tabular layout and filter options. As with Speech Star you can apply multiple filters and you can order the table by a column by clicking on its header (clicking a second time reverses the order). I’ve also included the option to open multiple videos in the same window. I haven’t included the playback speed options as the videos already include the clip at different speeds. Here’s a screenshot of how the feature looks:
On Thursday I had a Zoom call with Laura Rattray and Ailsa Boyd to discuss a new digital edition project they are in the process of planning. We had a really great meeting and their project has a lot of potential. I’ve offered to give technical advice and write any technical aspects of the proposal as and when required, and their plan is to submit the proposal in the autumn.
My final major task for the week was to continue to work on the Ramsay ‘Gentle Shepherd’ data. I overhauled the filter options that I implemented last week so they work in a less confusing way when multiple types are selected now. I’ve also imported the updated spreadsheet, taking the opportunity to trim whitespace to cut down on strange duplicates in the filter options. There are some typos you’ll need to fix in the spreadsheet, though (e.g. we have ‘Glagsgow’ and ‘Glagsow’) plus some dates still need to be fixed.
I then created an interactive map for the project and have incorporated the data for which there are latitude and longitude values. As with the Edinburgh Gazetteer map of reform societies (https://edinburghgazetteer.glasgow.ac.uk/map-of-reform-societies/) the number of performances at a venue is displayed in the map marker. Hover over a marker to see info about the venue. Click on it to open a list of performances. Note that when zoomed out it can be difficult to make out individual markers but we can’t really use clustering as on the Burns Supper map (https://burnsc21.glasgow.ac.uk/supper-map/) because this would get confusing: we’d have clustered numbers representing the number of markers in a cluster and then induvial markers with a number representing the number of performances. I guess we could remove the number of performances from the marker and just have this in the tooltip and / or popup, but it is quite useful to see all the numbers on the map. Here’s a screenshot of how the map currently looks:
I still need to migrate all of this to the University’s T4 system, which I aim to tackle next week.
Also this week I had discussions about migrating an externally hosted project website to Glasgow for Thomas Clancy. I received a copy of the files and database for the website and have checked over things and all is looking good. I also submitted a request for a temporary domain and I should be able to get a version of the site up and running next week. I also regenerated a list of possible duplicate authors in the Books and Borrowing system after the team had carried out some work to remove duplicates. I will be able to use the spreadsheet I have now to amalgamate duplicate authors, a task which I will tackle next week.
I spent most of the week continuing with the Speak For Yersel website, which is now nearing completion. A lot of my time was spent tweaking things that were already in place, and we had a Zoom call on Wednesday to discuss various matters too. I updated the ‘explore more’ age maps so they now include markers for young and old who didn’t select ‘scunnered’, meaning people can get an idea of the totals. I also changed the labels slightly and the new data types have been given two shades of grey and smaller markers, so the data is there but doesn’t catch the eye as much as the data for the selected term. I’ve updated the lexical ‘explore more’ maps so they now actually have labels and the ‘darker dots’ text (which didn’t make much sense for many maps) has been removed. Kinship terms now allow for two answers rather than one, which took some time to implement in order to differentiate this question type from the existing ‘up to 3 terms’ option. I also updated some of the pictures that are used and added in an ‘other’ option to some questions. I also updated the ‘Sounds about right’ quiz maps so that they display different legends that match the question words rather than the original questionnaire options. I needed to add in some manual overrides to the scripts that generate the data for use in the site for this to work.
I also added in proper text to the homepage and ‘about’ page. The former included a series of quotes above some paragraphs of text and I wrote a little script that highlighted each quote in turn, which looked rather nice. This then led onto the idea of having the quotes positioned on a map on the homepage instead, with different quotes in different places around Scotland. I therefore created an animated GIF based on some static map images that Mary had created and this looks pretty good.
I then spent some time researching geographical word clouds, which we had been hoping to incorporate into the site. After much Googling it would appear that there is no existing solution that does what we want, i.e. take a geographical area and use this as the boundaries for a word cloud, featuring different coloured words arranged at various angles and sizes to cover the area. One potential solution that I was pinning my hopes on was this one: https://github.com/JohnHenryEden/MapToWordCloud which promisingly states “Turn GeoJson polygon data into wordcloud picture of similar shape.”. I managed to get the demo code to run, but I can’t get it to actually display a word cloud, even though the specifications for one are in the code. I’ve tried investigating the code but I can’t figure out what’s going wrong. No errors are thrown and there’s very little documentation. All that happens is a map with a polygon area is displayed – no word cloud.
The word cloud aspects of the above are based on another package here: https://npm.io/package/wordcloud and this package allows you to specify a shape to use as an outline for the cloud, and one of the examples shows words taking up the shape of Taiwan: https://wordcloud2-js.timdream.org/#taiwan However, this is a static image not an interactive map – you can’t zoom into it or pan around it. One possible solution may be to create images of our regions, generate static word cloud images as with the above and then stitch the images together for form a single static map of Scotland. This would be a static image, though, and not comparable to the interactive maps we use elsewhere in the website. Programmatically stitching the individual region images together might also be quite tricky. I guess another option would be to just allow users to select an individual region and view the static word cloud (dynamically generated based on the data available when the user selects to view it) for the selected region, rather than joining them all together.
I also looked at some further options that Mary had tracked down. The word cloud on a leaflet map (http://hourann.com/2014/js-devs-dont-get-lost/leaflet-wordcloud.html?sydney) only uses a circle for the boundaries of the word cloud. All of the code is written around the use of a circle (e.g. using diameters to work out placement) so couldn’t really be adapted to work with a complex polygon. We could work out a central point for each region and have a circular word cloud positioned at that point, but we wouldn’t be able to make the words fill the entire region. The second of Mary’s links (https://www.jasondavies.com/wordcloud/) as far as I can tell is just a standard word cloud generator with no geographical options. The third option (https://github.com/peterschretlen/leaflet-wordcloud) has no demo or screenshot or much information about it and I’m afraid I can’t get it to work.
The final option (https://dagjomar.github.io/Leaflet.ParallaxMarker/) is pretty cool but it’s not really a word cloud as such. Instead it’s a bunch of labels set to specific lat/lng points and given different levels which sets their size and behaviour on scroll. We could use this to set the highest rated words to the largest level with lower rated words at lower level and position each randomly in a region, but it’s not really a word cloud and it would be likely that words would spill over into neighbouring regions.
Based on the limited options that appear to be out there, I think creating a working, interactive map-based word cloud would be a research project in itself and would take far more time than we have available.
Later on in the week Mary sent me the spreadsheet she’d been working on to list settlements found in postcode areas and to link these areas to the larger geographical regions we use. This is exactly what we needed to fill in the missing piece in our system and I wrote a script that successfully imported the data. For our 411 areas we now have 957 postcode records and 1638 settlement records. After that I needed to make some major updates to the system. Currently a person is associated with an area (e.g. ‘Aberdeen Southwest’) but I need to update this so that a person is associated with a specific settlement (e.g. ‘Ferryhill, Aberdeen’), which is then connected to the area and from the area to one of our 14 regions (e.g. ‘North East (Aberdeen)’).
I updated the system to make these changes and updated the ‘register’ form, which now features an autocomplete for the location – start typing a place and all matches appear. Behind the scenes the location is saved and connected up to areas and regions, meaning we can now start generating real data, rather than a person being assigned a random area. The perception follow-on now connects the respondent up with the larger region when selecting ‘listener is from’, although for now some of this data is not working.
I then needed to further update the registration page to add in an ‘outside Scotland’ option so people who did not grow up in Scotland can use the site. Adding in this option actually broke much of the site: registration requires an area with a geoJSON shape associated with the selected location otherwise it fails and the submission of answers requires this shape in order to generate a random marker point and this then failed when the shape wasn’t present. I updated the scripts to fix these issues, meaning an answer submitted by an ‘outside’ person has a zero for both latitude and longitude, but then I also needed to update the script that gets the map data to ensure that none of these ‘outside’ answers were returned in any of the data used in the site (both for maps and for non-map visualisations such as the sliders). So, much has changed and hopefully I haven’t broken anything whilst implementing these changes. It does now mean that ‘outside’ people can now be included and we can export and use their data in future, even though it is not used in the current site.
Further tweaks I implemented this week included: changing the font sizes of some headings and buttons; renaming the ‘activities’ and ‘more’ pages as requested; adding ‘back’ buttons from all ‘activity’ and ‘more’ pages back to the index pages; adding an intro page to the click exercise as previously it just launched into the exercise whereas all others have an intro. I also added summary pages to the end of the click and perception activities with links through to the ‘more’ pages and removed the temporary ‘skip to quiz’ option. I also added progress bars to the click and perception activities. Finally, I switched the location of the map legend from top right to top left as I realised when it was in the top right it was always obscuring Shetland whereas there’s nothing in the top left. This has meant I’ve had to move the region label to the top right instead.
Also this week I continued to work on the Allan Ramsay ‘Gentle Shepherd’ performance data. I added in faceted browsing to the tabular view, adding in a series of filter options for location, venue, adaptor and such things. You can select any combination of filters (e.g. multiple locations and multiple years in combination). When you select an item of one sort the limit options of other sorts update to only display those relevant to the limited data. However, the display of limiting options can get a bit confusing once multiple limiting types have been selected. I will try and sort this out next week. There are also multiple occurrences of items in the limiting options (e.g. two Glasgows) because the data has spaces in some rows (‘Glasgow’ vs ‘Glasgow ‘) and I’ll need to see about trimming these out next time I import the data.
Also this week I arranged for the old DSL server to be taken offline, as the new website has now been operating successfully for two weeks. I also had a chat with Katie Halsey about timescales for the development of the Books and Borrowers front-end. Finally, I imported a new disordered paediatric speech dataset into the Speech Star website. This included around double the number of records, new video files and a new ‘speaker code’ column. Finally, I participated in a Zoom call for the Scottish Place-Names database where we discussed the various place-names surveys that are in progress and the possiblity of created an overarching search across all systems.
Monday was the May Day holiday so it was a four-day week. I spent three of the available days working on the Speak For Yersel project. I completed work on the age-based questions for the lexical follow-on section. We wanted to split responses based on the age of the respondent, but I had a question about this: Should the age filters be fixed or dynamic? We say 18 and younger / 60 and older but we don’t register ages for users, we register dates of birth. I can therefore make the age filters fixed (i.e. birth >=2004 for 18, birth <=1962 for 60) or dynamic (e.g. birth >= currentyear-18 and birth <= currentyear -60). However, each of these approaches have issues. With the former with each passing year the boundaries will change. With the latter we end up losing data with each passing year (if someone is 18 when they submitted their data in 2022 then their data will be automatically excluded next year). I realised that there is a third way: When a person registers I log the exact time of registration so I can ascertain their age at the point when they registered and this will never change. I decided to do this instead, although it does mean that the answers of someone who is 18 today will be lumped in with the answers of someone who is 18 in 10 years time, which might cause issues. However, we can always change how the age boundaries work at a later date. Below is a screenshot of one of the date questions (more data is obviously still needed):
Whilst working on this I realised there is another problem with this type of question: Unless we have equal numbers of young and old respondents is it not likely that the data visualised on the map will be misleading? Say we have 100 ‘older’ respondents but 1000 ‘younger’ ones due to us targeting school children. If 50% of the older respondents say ‘scunnered’ then there will be 50 ‘older’ markers on the map. If 10% of the younger respondents say ‘scunnered’ then there will be 100 ‘younger’ markers on the map, meaning our answer ‘older’ (which is marked as ‘correct’) will look wrong even though statistically it is correct. I’m not sure how we can get around this unless we maybe plot the markers for each age group who don’t use the form as well, so as to let people see the total number of people in each group. Maybe using a smaller marker and / or a lighter shade for the people who didn’t say a form. I raised this issue with the team and this is the approach we will probably take.
I then moved onto the follow-on activities for the ‘Sounds about right’ section. Tis involved creating a ‘drag and drop’ feature where possible answers need to be dropped into boxes. The mockup suggested that the draggable boxes should disappear from the list of options when dropped elsewhere but I’ve changed it so that the choices don’t disappear from the list, but instead the action copies the contents to the dotted area when you drop your selection. The reason I’ve done it this way is that if the entire contents move over we could end up with someone dropping several into one box, or if they drop an option into the wrong box they would then have to drag it from the wrong box into the right one before they can try another word in the same box and it can all get very messy (e.g. if there are several words dropped into one box then do we consider this ‘correct’ if one of the words is the right one?). This way keeps things a lot simpler. However, it does mean the words the user has already successfully dropped still appear as selectable in the list, which might confuse people and I could disable or remove an option once it’s been correctly placed. Below is a screenshot of the activity with one of the options dropped:
The next activity asks people to see whether rules apply to all words with the same sounds by selecting ‘yes’ or ‘no’ for each. I set it up so that the ‘check answers’ button only appears once the user has selected ‘yes’ or ‘no’ for all of the words, and on checking the answers a tick or a cross is added to the right of the ‘yes’ and ‘no’ options. The user must correct their answers and select ‘check answers’ again before the ‘Check answers’ button is replaced with a ‘Next’ button. See a screenshot below:
With these in place I then moved onto the ‘perception’ activity, that I’d started to look into last week. I completed stages 1 and 2 of this activity, allowing the user to rate how they think a person from a region sounds using the seven sliding scales as criteria, as you can see below:
And then rating actual sound clips of speakers from certain areas using the same seven criteria, as the screenshot below shows:
Finally, I created the ‘explore more’ option for the perception activity, which consists of two sections. The first allows the user to select a region and view the average rating given by all respondents for that region, plotted on ‘read only’ versions of the same sliding scales. The team had requested that the scales animated to their new locations when a new region was selected and although it took me a little bit of time to implement this I got it working in the end and I think it works really well. The second option is very similar only it allows the user to select both the speaker and the listener, so you can see (for example) how people from Glasgow rate people from Edinburgh. At the moment we don’t have information in the system that links up a user and the broader region, so for now this option is using sample data, but the actual system is fully operational. Below is a screenshot of the first ‘explore’ option:
I feel like I’ve made really good progress with the project this week, but there is still a lot more to implement and I’ll continue with this next week.
I spent Friday working on another project, generating some views of performance data relating to performances of The Gentle Shepherd by Allan Ramsay ahead of a project launch at the end of the month. I’d been given a spreadsheet of the data so my first step was to write a little script to extract the data, format it (e.g. extracting years from the dates) and save it as JSON, which I would then use to generate a timeline, a table view and a map-based view. On Friday I completed an initial version of the timeline view and the table view.
I made the timeline vertical rather than horizontal as there are so many years and so much data that a horizontal timeline would be very long, and these days most people use touchscreens and are more used to scrolling down a page than along a page. I added a ‘jump to year’ feature that lists all of the years as buttons. Pressing on one of these scrolls to the appropriate year. There are rather a lot of years so I’ve hidden them in a ‘Jump to Year’ section. It may be better to have a drop-down list of options instead and I’ll maybe change this. Each year has a header and a dividing line and a ‘top’ button that allows you to quickly scroll back to the top of the timeline. Each item in the timeline is listed in a fixed-width box, with multiple boxes per row depending on your screen width and the data available. Currently all fields are displayed, but this can be changed.
The table view displays all of the data in a table. You can click on a column heading to sort the data by that heading. Pressing a heading a second time reverses the order. I still need to add in the filter options to the table view and then work on the map view once I’m given the latitude and longitude data that is still needed for this view to work. I’ll continue with this next week.
Also this week I make a couple of minor tweaks to the DSL website and had some discussions with the DSL people about the SLD data and the fate of the old DSL website. I also updated some of the data for the Books and Borrowing project and had a chat with Thomas Clancy about hosting an external website that is in danger of disappearing.
We launched the new version of the DSL website on Tuesday this week, which involved switching the domain name to point at the new server where I’d been developing the new site. When we’ve done this previously (e.g. for the Anglo-Norman Dictionary) the switchover has been pretty speedy, but this time it took about 24 hours for the DNS updates to propagate, during which time the site was working for some people and not for others. This is because there is a single SSL certificate for the dsl.ac.uk domain and as it was moved to the new server, the site on the old server (which was still being accessed by people whose ISP’s had not updated their domain name servers) was displaying a certificate error. This was all a bit frustrating as the problem was out of our hands, but thankfully everything was working normally again by Wednesday.
I made a few final tweaks to the site this week too, including updating the text that is displayed when too many results are returned, updating the ‘cite this entry’ text, fixing a few broken links and fixing the directory permissions on the new site to allow file uploads. I also gave some advice about the layout of a page for a new Scots / Polish app that the DSL people are going to publish.
I spent almost all of the rest of the week working on the Speak For Yersel project, for which I still have an awful lot to do in a pretty short period of time, as we need to pilot the resource in schools during the week of the 13th of June and need to sent it out to other people for testing and to populate it with initial data before then. We had a team meeting on Thursday to go through some of the outstanding tasks, which was helpful.
This week I worked on the maps quite a bit, making the markers smaller and giving them a white border to help them stand out a bit. I updated the rating colours as suggested, although I think we might need to change some of the shades used for ratings and words as after using the maps quite a bit I personally find it almost impossible to differentiate some of the shades, as you can see in the screenshot below. We have all the colours of the rainbow at our disposal and while I can appreciate why shades are preferred from an aesthetical point of view, in terms of usability it seems a bit silly to me. I remember having this discussion with SCOSYA too. I think it is MUCH easier to read the maps when different colours are used, as with Our Dialects (e.g. https://www.ourdialects.uk/maps/bread/).
As you can also see from the above screenshot, I implemented the map legends as well, with only the options that have been chosen and have data appearing in the legend. Options appear with their text, a coloured spot so you can tell which option is which, and a checkbox that allows you to turn on / off a particular answer, which I think will be helpful in differentiating the data once the map fills up. For the ‘sound choice’ questions a ‘play’ button appears next to each option in the legend. I then ensured that the maps work for the quiz questions too: rather than showing a map of answers submitted for the quiz question the maps now display the data for the associated questionnaire (e.g. the ‘Gonnae you’ map). Maps are also now working for the ‘Explore more’ section too. I also added in the pop-up for ‘Attribution and Copyright’ (the link in the bottom right of the map).
I then added further quiz questions to the ‘Give your word’ exercise, but the final quiz question in the document I was referencing had a very different structure, with multiple specific answer options from several different questions on the same map. I spent about half a day making updates to the system to allow for such a question structure. I needed to update the database structure, the way data is pulled into the website, the way maps are generated, how quiz questions are displayed and how they are processed.
The multi-choice quiz works in a similar way to the multi-choice questionnaire in that you can select more than one answer. Unlike the questionnaire there is no limit to the number of options you can select. When at least one choice is selected a ‘check your answers’ button appears. The map displays all of the data for each of the listed words, even though these come from different questionnaires (this took some figuring out). There are 9 words here and we only have 8 shades so the ninth is currently appearing as red. The map legend lists the words alphabetically, which doesn’t match up with the quiz option order, but I can’t do anything about this (at least not without a lot of hacking about). You can turn off/on map layers to help see the coverage.
When you press on the ‘Check your answers’ button all quiz options are greyed out and your selection is compared to the correct answers. You get a tick for a correct one and a cross for an incorrect one. In addition, any options you didn’t select that are correct are given a tick (in the greyed out button) so you can see what was correct that you missed. If you selected all of the correct answers and didn’t select any incorrect answers then the overall question is marked as correct in the tally that gives your final score. If you missed any correct answers or selected any incorrect ones then this question is not counted as correct overall. Below is a screenshot showing how this type of question works:
Unfortunately, when we met on Thursday it turned out that Jennifer and Mary were not wanting this question to be presented on one single map, but instead for each answer option to have its own map, meaning the time I spent developing the above was wasted. However, it does mean the question is much more simple, which is probably a good thing. We decided to split the question up into individual questions to make things more straightforward for users and to ensure that getting one of the options incorrect didn’t mean they were marked as getting the entire multi-part question wrong.
Also this week I began implementing the perception questionnaire with seven interactive sliders allowing the user to rate an accent. Styling the sliders was initially rather tricky but thankfully I found a handy resource that allows you to customise a slider and generates the CSS for you (https://www.cssportal.com/style-input-range/). Below is a screenshot of the perception activity as it currently stands:
I also replaced one of the sound recordings and fixed the perception activity layout on narrow screens (as previously on narrow screens the labels ended up positioned at the wrong ends of the slider). I added a ‘continue’ button under the perception activity that is greyed out and added a check to see whether the user has pressed on every slider. If they have then the ‘continue’ button text changes and is no longer greyed out. I also added area names to the top-left corner of the map when you hover over an area, so now no-one will confuse Orkney and Shetland!
We had also agreed to create a ‘more activities’ page and to have follow-on activities and the ‘explore more’ maps situated there. I created a new top-level menu item currently labelled ‘More’. If you click on this you find an index page similar to the ‘Activities’ page. Press on an option (only the first page options work so far) and you’re given the choice to either start the further activities (not functioning yet) or explore the maps. The latter is fully functional. In the regular activities page I then removed the ‘explore more stage’ so that now when you finish the quiz the button underneath your score leads you to the ‘More’ page for the exercise in question. Finally, I began working on the follow-on activities that display age-based maps, but I’ll discuss these in more detail next week.
I also spoke to Laura Rattray and Ailsa Boyd about a proposal they are putting together and arranged a Zoom meeting with them in a couple of weeks and spoke to Craig Lamont about the Ramsay project I’m hopefully going to be able to start working on next week.
I divided most of my time between the Speak For Yersel project and the Dictionaries of the Scots Language this week. For Speak For Yersel I continued to work on the user management side of things. I implemented the registration form (apart from the ‘where you live’ bit, which still requires data) and all now works, uploading the user’s details to our database and saving them within the user’s browser using HTML5 Storage. I added in checks to ensure that a year of birth and gender must be supplied too.
I then updated all activities and quizzes so that the user’s answers are uploaded to our database, tracking the user throughout the site so we can tell which user has submitted what. For the ‘click map’ activity I also record the latitude and longitude of the user’s markers when they check their answers, although a user can check their answers multiple times, and each time the answers will be logged, even if the user has pressed on the ‘view correct locations’ first. Transcript sections and specific millisecond times are stored in our database for the main click activity now, and I’ve updated the interface for this so that the output is no longer displayed on screen.
With all of this in place I then began working on the maps, replacing the placeholder maps and their sample data with maps that use real data. Now when a user selects an option a random location within their chosen area is generated and stored along with their answer. As we still don’t have selectable area data at the point of registration, whenever you register with the site at the moment you are randomly assigned to one or our 411 areas, so by registering and answering some questions test data is then generated. My first two test users were assigned areas south of Inverness and around Dunoon.
With location data now being saved for answers I then updated all of the maps on the site to remove the sample data and display the real data. The quiz and ‘explore’ maps are not working properly yet but the general activity ones are. I replaced the geographical areas visible on the map with those as used in the click map, as requested, but have removed the colours we used on the click map as they were making the markers hard to see. Acceptability questions use the four rating colours as were used on the sample maps. Other questions use the ‘lexical’ colours (up to 8 different ones) as specified.
The markers were very small and difficult to spot when there are so few of them so I placed a little check that alters their size depending on the number of returned markers. If there are less than 100 then each marker is size 6. If there are 100 or more then the size is 3. Previously all markers were size 2. I may update the marker size or put more granular size options in place in future. The answer submitted by the current user appears on the map when they view the map, which I think is nice. There is still a lot to do, though. I still need to implement a legend for the map so you can actually tell which coloured marker refers to what, and also provide links to the audio clips where applicable. I also still need to implement the quiz question and ‘explore’ maps as I mentioned. I’ll look into these issues next week.
For the DSL I processed the latest data export from the DSL’s editing system and set up a new version of the API that uses it. The test DSL website now uses this API and is pretty much ready to go live next week. After that I spent some time tweaking the search facilities of the new site. Rhona had noticed that searches involving two single character wildcards (question marks) were returning unexpected results and I spent some time investigating this.
A second thing was causing further problems: A quick search by default performs an exact match search (surrounded by double quotes) if you ignore the dropdown suggestions and press the search button. But an exact match was set up to be just that – single wildcard characters were not being treated as wildcard characters, meaning a search for “sc??m” was looking for exactly that and finding nothing. I’ve fixed this now, allowing single character wildcards to appear within an exact search.
After fixing this we realised that the new site’s use of the asterisk wildcard didn’t match its use in the live site. Rhona was expected a search such as ‘sc*m’ to work on the new site, returning all headwords beginning ‘sc’ and ending in ‘m’. However, in the new site the asterisk wildcard only matches the beginning or end of words, e.g. ‘wor*’ finds all words beginning with ‘wor’ and ‘*ord’ finds all words ending with ‘ord’. You can combine the two with a Boolean search, though: ‘sc* AND *m’ and this will work in exactly the same way as ‘sc*m’.
However, I decided to enable the mid-wildcard search on the new site in addition to using Boolean AND, because it’s better to be consistent with the old site, plus I also discovered that the full text search in the new site does allow for mid-asterisk searches. I therefore spent a bit of time implementing the mid-asterisk search, both in the drop-down list of options in the quick search box as well as the main quick search and the advanced search headword search.
Rhona then spotted that a full-text mid-asterisk search was listing results alphabetically rather than by relevance. I looked into this and it seems to be a limitation with that sort of wildcard search in the Solr search engine. If you look here https://solr.apache.org/guide/8_7/the-standard-query-parser.html#differences-between-lucenes-classic-query-parser-and-solrs-standard-query-parser the penultimate bullet point says “Range queries (“[a TO z]”), prefix queries (“a*”), and wildcard queries (“a*b”) are constant-scoring (all matching documents get an equal score).”
I’m guessing the original API that powers the live site uses Lucene rather than Solr’s indexing system, but I don’t really know for certain. Also, while the live site’s ordering of mid-asterisk wildcard searches is definitely not alphabetical, it doesn’t really seem to be organising properly by relevance either. I’m afraid we might just have to live with alphabetical ordering for mid-asterisk search results, and I’ll alter the ‘Results are ordered’ statement in such cases to make it clearer that the ordering is alphabetical.
My final DSL tasks for the week were to make some tweaks to the XSLT that processes the layout of bibliographical entries. This involved fixing the size of author names, ensuring that multiple authors are handled correctly and adding in editors’ names for SND items. I also spotted a few layout issues that are still cropping up. The order of some elements is displayed incorrectly and some individual <bibl> items have multiple titles and the stylesheet isn’t expecting this so only displays the first ones. I think I may need to completely rewrite the stylesheet to fix these issues. As there were lots of rules for arranging the bibliography I wrote the stylesheet to pick out and display specific elements rather than straightforwardly going through the XML and transforming each XML tag into a corresponding HTML tag. This meant I could ensure (for example) authors always appear first and titles each get indented, but it is rather rigid – any content that isn’t structured as the stylesheet expects may get displayed in the wrong place or not at all (like the unexpected second titles). I’m afraid I’m not going to have time to rewrite the stylesheet before the launch of the new site next week and this update will need to be added to the list of things to do for a future release.
Also this week I fixed an issue with the Historical Thesaurus which involved shifting a category and its children one level up and helped sort out an issue with an email address for a project using a top-level ‘ac.uk’ domain. Next week I’ll hopefully launch the new version of the DSL on Tuesday and press on with the outstanding Speak For Yersel exercises.
