A Domain Ontology Development Environment Using a MRD and Text Corpus

In this paper, we describe how to exploit a machine-readable dictionary (MRD) and domain-specific text corpus in supporting the construction of domain ontologies that specify taxonomic and non-taxonomic relationships among given domain concepts. A) In building taxonomic relationships (hierarchically structure) of domain concepts, some hierarchically structure can be extracted from a MRD with marked sub-trees that may be modified by a domain expert, using matching result analysis and trimmed result analysis. B) In building non-taxonomic relationships (specification templates) of domain concepts, we construct concept specification templates that come from pairs of concepts extracted from text corpus, using WordSpace and an association rule algorithm. A domain expert modifies taxonomic and non-taxonomic relationships later. Through the case study with CISG, we make sure that our system can work to support the process of constructing domain ontologies with a MRD and text corpus.
