Extending a Lexicon Ontology for Intelligent Information Integration

One of the current research on the Semantic Web areais semantic annotation of information sources. On-line lexical ontologie can be exploited as a-priori common knowledge to provide easily understandable, machine-readable metadata. Nevertheless, the absence of terms related to specific domains causes a loss of semantics.In this paper we present WNEditor, a tool that aims at guidingthe annotation designer during the creation of a domain lexiconontology, extending the pre-existing WordNet ontology. New terms, meanings and relations between terms are virtually added and managed by preserving the WordNet’s internal organization.
