This article mainly discusses how to extract the interested information from massive amounts of micro-blogs and recommend right user, which is a hot research area in recommendation systems social networks, too.To solve this problem, model called Multi-tags Latent Dirichlet Allocation proposed.Using model, topics paid attention by users can be mined effectively defect low degree differentiation for short blog content settled.Experiments showed that tags user's micro-blog figured out with...
The traditional collaborative filtering algorithm cannot response user interest with time and is lack of effectiveness.These problems lead to poor recommendation quality.On the basis neighbor-based filtering, a fused method improved similarity proposed.To begin with, we compute from global perspectives obtained Jaccard similarity, local Bhattacharyya Coefficient.Furthermore, adopt forgetting curve represent preference, adding weight new update interest.Finally, make prediction by calculating...
