Time weighted collaborative filtering algorithms based on resources category
基于资源类的时间加权协作过滤算法*

Currently e-Learning as an important teaching methods,its individual requirements are increasing.Collaborative filtering is the most common application of personalized recommendation algorithm now,but the sparsity of data and the scalability of algorithm has been a collaborative filtering algorithms faced by the two main issues.Proposed a time weighted collaborative filtering algorithm based on resources category,which not only reduced the data sparsity and dimensionality,and narrowed the area of the neares...
