This paper gives out an information retrieval system model based on ontology. First of all, the weak point and its reason are analyzed for traditional information retrieval system,. Then, the concept of Ontology and its application in intelligent retrieval domain is introduced. Afterwards, a information retrieval system structure model, based on domain ontology, was proposed, in which it was introduced on how to utilize domain knowledge of ontology to realize query based on concept during the process of information retrieval.
