Abstract  Aiming at the difficulty of project features expression,this paper brings forward to extract and represent it with vague sets theory.Then similar item is clustered to predict missing evaluation values of item, thus eliminating the sparsity problem of collaborative filtering recommendation. Based on the predicted rating matrix,similar users are clustered,and collaborative filtering recommendation is implemented in the space of item cluster to give more targeted recommendation. Evaluation results show that the proposed method is more effective both in the accuracy and in relevance of recommendations.
Key wordsRecommender system      Collaborative filtering      Item similarity      Content-based recommendation      Vague sets
