Abstract In order to improve the precision and the quality of the literature retrieval, this paper explores similarity computing scheme based on Vector Space Model (VSM), and describes the clustering algorithm of biomedical literature on the basis of similarity model. Applying the method of similarity algorithm and cluster analysis, the searched papers can be ranked by degree of similarity.
