Schema Evolution publication categorizer

Abstract. In this paper, we present a novel approach for the management of the
ontology-based knowledge management system. It extends our previous work
in the ontology evolution by taking into account the usage of the ontology in the
knowledge management system. The approach is mainly based on the analysis
of the users’ behaviour in two phases of a knowledge management cycle: (i) in
providing knowledge by analysing the quality of annotations and (ii) in
searching for knowledge by analysing users’ queries and the responses from the
knowledge repository. This analysis results in the recommendations for changes
in the underlying ontology, the annotations and/or the knowledge repository in
order to make the whole system more efficient. We present two short case
studies.
