Research on Domain Ontology Construction in Military Intelligence

This paper is started from addressing the common automatic method of ontology construction. Then, from viewpoint of the military intelligent processing, the two-level domain ontology architecture is designed. One level is the keyword ontology. The other level is the instance ontology. Different level has different ontology architecture. At last, the domain ontology is constructed by reusing the existing ontology together with extracting ontology from text information and extending it.
