Hi All,

This is something I should have posted about a while ago. Thankfully the
brownsauce announcement prompted me to get a working demo together!

VlUM is a visualisation of large user models, expressed in a simple RDF
vocabulary, that allows the user to easily explore the model for certain
types of interesting data.

<http://www.it.usyd.edu.au/~jimu/vlum/>

It was originally designed as an adjunct to an online assessment system to
help medical students find their areas of weakness or strength. In this demo
I've turned to another domain, that of showing personalised recommendations
for movies. The movies are taken from the IMDB, and arranged in a graph
according to similarity in cast. The recommendation is based on the IMDB
recommendation for that movie, which is given by a voting system. In a
non-demo system would ideally be personalised.

A full description of the whys, hows etc may be found in my PhD thesis which
you can get from the site listed above.

caveats:

*) It uses java plugin 1.4. This saves downloading xml parsers and the regex
library.

*) The RDF serialisation is probably somewhat dated. The files used were
generated in 1999(!). Moving to a more 'considered' format and using
something like jena for parsing is on the to-do-list.

Cheers,

James
