In view of the current information retrieval systems,there exists an important problem that is low precision and low recall rate.After analyzing the used methods in information retrieval systems,a new method is proposed,which is based on the concept of semantic space to improve the precision and recall rate.The experimental results show that the method can greatly enhance user retrieval precision and recall rate compared to traditional methods.
