Thesaurus or logical ontology, which do we need for mining text?
It has been claimed that domain ontology is necessary not only for effective and efficient information sharing but also for information extraction and text mining. In particular, the need of common ontology for information sharing among different research communities has been recognized in bio-medical fields, and several domain ontologies are now being built (GO 2003). This is because of the sheer complexity of the semantic space and a huge number of concepts or terms used in these specific domains.
