Ding Chang-song · Computer Technology and Development · 2011
As an important tool for knowledge reuse,knowledge sharing and modeling,ontology,especially domain ontology,plays an more and more important role in the information extraction system in recent years.The conception of ontology and the modeling criterion of ontology is introduced firstly.And then the ordinary existing modeling methods of ontology are analyzed.After comparatively analysing those kinds of modeling methods of ontology,a new modeling method of domain ontology is advanced according to the principle of information extraction and the concept of software engineering.It performs well in logic and operation and can be adopted in modeling certain domain ontology.
