Ontology Modularization for Knowledge Selection: Experiments and Evaluations

, , , and . Database and Expert Systems Applications, (2007)

Abstract

Problems with large monolithical ontologies in terms of reusability, scalability and maintenance have led to an increasing interest in modularization techniques for ontologies. Currently, existing work suffers from the fact that the notion of modularizationis not as well understood in the context of ontologies as it is in software engineering. In this paper, we experiment on applyingstate-of-the-art tools for ontology modularization in the context of a concrete application: the automatic selection of knowledgecomponents to be used for Web page annotation and semantic browsing. We conclude that, in a broader context, an evaluationframework is required to guide the choice of a modularization tool, in accordance with the requirements of the consideredapplication.
