Resumo(s)
In this paper we discuss how the inclusion of semantic functionalities
in a Learning Objects Repository allows a better characterization of the learning
materials enclosed and improves their retrieval through the adoption of some
query expansion strategies. Thus, we started to regard the use of ontologies to
automatically suggest additional concepts when users are filling some metadata
fields and add new terms to the ones initially provided when users specify the
keywords with interest in a query. Dealing with different domain areas and
having considered impractical the development of many different ontologies,
we adopted some strategies for reusing ontologies in order to have the
knowledge necessary in our institutional repository. In this paper we make a
review of the area of knowledge reuse and discuss our approach.
