Abstract: This paper tries to describe the ontology in a formal way and introduce one of its-application: an information retrieval method based on ontology. This method overcomes the insufficiency of information overloading and missing caused by the keyword-based retrieval methods. So it more conforms to the custom of human thought, and the results become more rational and useful. This method is verified by an experimental protosystem.
