Aimed at the problem that current IR model could not supply the sematic retrieval,DL-VSM(description logic-based VSM for semantic retrieval) is proposed.This model expressed the documents and user's requests by the ontology descripted by description logic and put forward the method which can compute the similarity between the logic view of documents and requests.The data structure of this model is given.Experiment and model analyse show that F-value is improved 10% or so higher than VSM and this model performed very well.
