Fujitsu has demonstrated a “search tool for the Semantic Web” called the Business Information Navigator that use embedded metadata to identify relationships between documents spread throughout an organization and improve search results. The system was demonstrated at the Fujitsu Forum 2005, a company technology showcase that took place in Tokyo in mid July. The application visualizes search results using position and size for importance and different links reflecting the strength of the relationships between them. Information on the relevance of the documents to company divisions or individuals can be accessed via the graph. Fujitsu is said to be testing the system with an un-named domestic financial institution. I’ve been unable to find any additional information on this other than this story and related ones. It will be interesting to see if they use RDFS or OWL and if they do any inferencing.
