基于联合聚类和C-RA组合相似度的协同过滤算法
COLLABORATIVE FILTERING ALGORITHM BASED ON CO-CLUSTERING AND C-RA COMBINED SIMILARITY
摘要
Abstract
In order to overcome the sparse data and cold start of traditional collaborative filtering recommendation algorithm, a collaborative filtering algorithm based on co-clustering and C-RA combined similarity is proposed.First, co-clustering algorithm is used to simultaneously obtain user and item neighborhoods.Secondly, the result of co-clustering is used on rating matrix.Finally, C-RA combined similarity is used to calculate the similarity of users and recommend.Experimental results show that the proposed method not only effectively improves the accuracy of the recommended results, but also solves problems of user cold start and data sparsity.关键词
