Problem area: knowledge visualization, ontologies
UM, dr. Floris Wiesman
In the previous phase of the ToKeN2000 project, a metabrowser for information retrieval
(IR) was developed, with a special focus on the presearch (i.e., the phase
where the user has not yet started searching for documents but is searching
for the relevant concepts). The idea is to present the user with a partial
view of the thesaurus, which changes depending on filters chosen by the user.
Currently, there is much interest in ontologies for use in Internet
interoperability. Especially in digital libraries, ontologies are key where it
comes to searching heterogeneous information databases. To enable the
building, maintenance, and use of ontologies various formalisms and tools are
available. The proposed project aims at a generic tool for searching,
accessing, and editing ontologies. It will be generic in the sense that it
independent of the representation formalism used. As a starting point will
serve the ontology part of the ARIA database.
