AX-S Widget Demonstrator – Complete!

The demonstrator is now live at: http://igsl.co.uk/xxp/ax-s/ou.html.  This demonstrator provides the AX-S search for Open University XCRI-CAP 1.2 data on a mock-up of the look-and-feel of the Open University website.

As explained in an earlier post the AX-S search facility provides concept-based subject search functionality that retrieves records not only matching the user’s selected subject search term itself, but also matching broader and narrower linked concepts. Records were classified with JACS3 codes, which were used to link the courses to a specially constructed thesaurus of terms. When searching, each retrieved record is ranked in the search results list in accordance with how close its JACS3 subject is to the user’s search term within the thesaurus. This functionality can be provided via the AX-S Widget to any institution with an XCRI-CAP 1.2 feed classified with a recognised subject coding scheme (such as JACS3, LDCS, SSA and so on) for use on their website and has the potential to be developed further with additional filters taken from the XCRI-CAP data such as studyMode or attendancePattern.

There were three main work strands in the project: development of the widget itself, development of back-end functions, such as data loading and search functionality, and construction of our bespoke thesaurus of subject terms, on which the searching is based. Software development by InGenius Solutions was key to the success of the project. It was also dependent on classification of the data with JACS3 codes, handled by APS (who also converted the OU data to XCRI-CAP 1.2), and of course, supply of courses data and the website look-and-feel by The Open University.

The project involved more updating of our original thesaurus of terms than was initially expected, but this has now been largely finalised. Some small improvements can still be made by tidying up the detailed formatting of the thesaurus and these are in progress. The demonstrator has been systematically user tested and refined and the code and documentation is available on GitHub.

The AX-S Widget Demonstrator shows how standardised data and small modular software components can be combined to provide a new service that would be very expensive for a single institution to develop, but cost-effective when developed centrally for use across a larger number of institutions. We are pleased to say that there is already interest from several Universities to include this widget on their websites, and we hope to see it in live use soon.
