Knowledge Organization Systems (KOS), such as classifications, gazetteers, taxonomies and thesauri, are used to semantically structure a subject domain, for the general purposes of document retrieval. They act as semantic road maps and make possible a common orientation by indexers and searchers (whether human or machine). Thus the synonym and semantic problems of current web search engines can be alleviated by shared intellectual vocabularies, which also serve as a resource for expressing an indexing concept or information need. A vast legacy of these vocabularies and indexed collections is available and they can also act as components of higher level ontologies. Prototype networked KOS services and applications are now reaching the stage where they might begin to exploit common representations and protocols. This would provide the basis for terminology services, applicable across a wide range of applications in teaching, learning and research.

The seminar will present results from the FACET project which explored semantic expansion in query and browsing, based on thesaurus relationships. It will go on to discuss implications for terminology (web) services and demonstrate examples of some ongoing work.

Speaker Biography

Doug Tudhope

Doug has a BSc in Computer Science from the University of Edinburgh. He completed his PhD in 1981 from the University of Wales (Swansea) on knowledge-based recognition of logic schematic diagrams. Before joining the University of Glamorgan in 1989, he worked as a programmer/analyst at the University of California, San Diego for the Faint Object Spectrograph project, one of the original instruments on the Hubble Space Telescope. At Glamorgan, he lead the the Hypermedia Research Unit and is the Field Leader for Computer Science.

He is the Editor of the journal The New Review of Hypermedia and Multimedia (NRHM) and is on the Editorial Board of the Journal of Digital Iinformation (JoDI). He is currently unit leader for Hypermedia Research at the University of Glamorgan.
