| Abstract: | The analysis of similarity and relevancy based on ontology is put forward to mining fully the background knowledge provide by domain ontology.By semantic reasoning make connotative semantic clear to provide the comprehensible semantic to computer.An ontology-based Web information retrieval model is proposed.The experiment proves that this method can improve the precision and recall. |

| Keywords: | ontology semantic query semantic similarity semantic relevancy precision recall |
