user performance using a Topic Maps-based
ontology information retrieval system. Although
the results of user performance using Topic Maps
have improved, more research is needed in the
following areas to maximize the collaboration.
First, it will be necessary to conduct a user study
to evaluate different aspects of Topic Maps, such
as internal and external occurrences. Second,
further research should be directed at migration
of existing metadata. Sufficient metadata already
exists to further collaboration in libraries and
information agencies.
This chapter explored critical components, ontol-
ogy, of the current Semantic Web Architecture.
Topic Maps and RDF, ontology languages or data
models, have similar goals; however, each has
unique advantages. This chapter addresses the
issues of the current Semantic Web Architecture,
three differences between RDF and Topic Maps,
and selection guidelines between two data models.
This chapter also presents a study which measures
