On the role of a librarian agent in ontology-based knowledge management systems

Abstract: In this paper, we present an agent-based approach for
the improvement of searching in an ontology-based knowledge
management system. The system implements a library scenario in
which users query the repository for knowledge resources.
Consequently, the so-called Librarian Agent plays the role of
the human librarian in the traditional library – it uses all
possible information, about the domain vocabulary, the behaviour
of previous users and the capacity of the knowledge repository,
in order to help users find the resources they are interested
in. We partially implemented the approach in the Web Portal of
our Institute and some initial evaluation results are shown.
