Research on Method of Domain Ontology Building Based on Web
Methodology of ontology building based on Web resources can not only shortens the period of constructing the ontology but also extends the application fields of the ontology. while a lot of progress has been achieved, there are still some difficulties in the Web data extraction and knowledge acquisition. This paper focuses on the characteristics of ontology construction data such as dynamics, largeness, variation and openness as well as the fundamental problem——formal representation method. The paper also discusses the key techniques and difficulties of ontology construction. An initial system structure has been developed, which provides a guideline for the ontology construction based on web.
