Automatic Ontology Construction Approaches and Its Application on Military Intelligence

Ontology is a method of expressing knowledge. Now the research on the automatic ontology construction has become very popular. In this paper, we introduce the principles of ontology construction, as well as the several methods of automatic construction and particularly analyze their characteristics. Finally, the ontology in military intelligence is constructed automatically by using the existing resources, thesaurus and database. The thesaurus provides classes information for the ontology, while the database provides the instances. The test result shows the accuracy of the semantic relations in the ontology is 86.23%, and the ontology includes the complete information on the instances.
