【Abstract】 This paper introduces an unstructured information retrieval mechanism based on the ontology.The mechanism provides a uniform semantic level scheme for unstructured information query in the application systems which are in existence,and it overcomes the insufficiency of information overloading and missing caused by the keyword -based retrieval,so it conforms to the custom of human thought more closely,and the results become more rational and useful.This mechanism can promote the capability of application systems and improve them application value.It first introduces the general framework of the mechanism,and then the information retrieval language FL-Plus, search engine and optimization algorithm.更多还原
