Text Mining Approach to Ontology Enrichment

October 1, 2003 - December 1, 2004

Ontologies have been widely accepted as the most advanced knowledge representation model. They are among the most important building blocks of semantic web, hence, very crucial for the success of semantic web. Huge effort is needed from the domain expert in order to construct ontologies manually. There is a need for semi-automatic approach in ontology building which will help the domain expert in constructing extensive domain ontologies efficiently. We propose the use of text mining techniques, especially mining the domain specific texts and glossaries/dictionaries in order to find groups of concepts/terms which are related to each other. Such groups of related concepts/terms will enable the domain expert to either, evaluate and update the existing ontology in case those concepts are already defined in the ontology, or to enrich the existing ontology in case those concepts are not defined. This will be an iterative refinement process with the newly available knowledge bases and/or domain specific texts or glossaries.
