Abstract:

Considering the characteristics of knowledge in the domain of news community, and taking the network application of knowledge in the domain of news community as the purpose, we use the semi-automatic ontology construction method, and expand the conceptual structure of ontology according to the media process to construct the top-level ontology model and middle-level ontology model oriented to the news website application in the domain of news community based on the general ontology WordNet and news subject classification on different levels in the ODP open directory. In addition, we develop a news community domain ontology by using the ontology construction tool Protégé4.1.

Key words: news community, domain ontology, ontology construction, middle-level ontology
