With the rapid development of social network in recent years,a huge number of social information has been produced.As traditional recommender systems often face data sparsity and cold-start problem,the use of social information has attracted many researchers' attention to improve the prediction accuracy of recommender systems.Social trust and social relation have been proven useful to improve the performance of recommendation.Based on the classic collaborative filtering technique,we propose a PCCTTF recommender method that takes the rating time of users,social trust among users,and item tags into consideration,then do the item recommending.Experimental results show that the PCCTTF method has better prediction accuracy than classical collaborative filtering technique and the state-of-the-art recommender methods,and can also effectively alleviate data sparsity and cold-start problem.Furthermore,the PCCTTF method has better performance than all the compared methods while counting against shilling attacks.
