Research of Web Intelligent Retrieval Based on Ontology

Aiming at the problem of traditional information retrieval based on key words, a domain ontology-based semantic information retrieval model is proposed.On the basis of establishing the relationship between the ontology concept and the content of document, pre-processes the user's query, calculates the similarity using domain ontology, and shows the sorted relative documents corresponding to the query.The built Web-based intelligent retrieval prototype validates the effectiveness of the model preliminarily.
