Victoria Redfern demonstrated her RootZa "... online tool to assist researchers, students, professionals and the general public to search the internet or www". There is a paper in the ACM digital library by Victoria: "World wide web: online core concept thesaucratic database development to improve information seeking". Also her patent application "ENHANCED SEARCHING USING A THESAURUS" (WIPO Patent Application WO/2007/012120). The tool has a visualization of the results as a diagram but the claims for invention appear to be about how the thesaurus is generated. This may be of use for Defence classification systems.
