An Integrated Method for Text Information Retrieval

The algebra-based and ontology-based information retrieval model are investigated in this paper,from which we know the two reinforce each other to some extent. Based on this observation, an integrated method for information retrieval is presented by taking the advantage of these two models. Then, an effective matching algorithm for pairing of different characteristic words is presented to improve the similarity calculating between the query and text. The experimental results show that, compared with the algebra-based and ontology-based models, the proposed method obviously gets a better precision and recall.
