AX-S (Advanced XCRI-CAP Search) Widget Demonstrator: Introduction

with one comment

The AX-S Widget is a small chunk of code which can be embedded on any institution’s website. It provides ‘best of breed’ subject searching using a specially designed search algorithm to provide more accurate and more relevant results than can be obtained through other methods, for example UCAS’ Course Search or the National Careers Service’s course search service.

It uses a university or college XCRI-CAP 1.2 feed to populate its data source. The use of the XCRI-CAP standard enables the search data source to be kept synchronised with the live courses information on the institution’s website.

To try the AX-S search, go to the Demonstrator web page at http://igsl.co.uk/xxp/ax-s/ou.html and start typing your topic into the ‘Search for:’ box and select one of the search terms that presents itself. The system automatically matches your text with its search terms as you type. You can also optionally select an Education Level from the drop-down list. When you hit the ‘Search’ button, the widget sends your choices off to the search engine held on the XXP (XCRI eXchange Platform) server, which carries out the search. It returns a list of courses matched conceptually to your choice of search term. As well as courses that match exactly with the topic you’ve chosen, the results will include courses in topics that are broader or narrower than your topic, sorted by their relevance to your choice.

For example, using the term “software engineering” will give you results not only in Software Engineering itself at the top of the list, but also lower down the list courses in more general Computing, then in development using specific techniques, such as object-oriented approaches and Java. These results are all widening out from Software Engineering, or narrowing in to topics within the field.

The Widget Demonstrator uses sample data from, and the look-and-feel of, the Open University website (with their permission), but is not currently a live search on their website. For the above example the Demonstrator in its current version brings back over 30 results. The current Open University website keyword-based search brings back 5 specific courses at its top level, plus Software Engineering as a subject of research, and a link to general Computing and IT. However, it does not include conceptual matches, such as management of software projects or computing for commerce and industry, but is limited to results with the words “software” and “engineering” in them. The advanced search functionality of the AX-S demonstrator has also been tested successfully against leading web search services, such as UCAS Course Search and the National Careers Services’ search facilities.
