Abstract: A novel method is proposed and realized based on Markov Network, which can construct Markov Network according to the co-occurrence information of the terms in collection. The relevance probability between document and query is computed by adding additional evidential sources to the model from the term space Markov Network. Experiment results show that our Markov model method can get more effective performances compared with other methods.

Key words: query evidential source , information retrieval model, Markov Network
