| 摘 要： | 为了解决推荐算法中用户标签稀疏、推荐准确度不高的问题，提出了一种基于用户标签的微博推荐算法。利用TextRank排序方法提取用户发布微博中的关键词，并对该关键词进行扩展，将其作为表示用户兴趣的标签；再根据微博的效应函数和生命周期形成待推荐的微博列表，计算用户标签及其同义词在待推荐微博列表
中出现的次数，将出现次数较多的TOP-k条微博推荐给用户。通过实验验证，该算法能够有效地解决用户标签的稀疏性问题，并能提高推荐算法的准确性。

| Abstract: | In order to solve the problem of data sparsity of user''s tag in the recommendation and the low accuracy, this paper put forward a algorithm recommended by microblog which based on user''s tag. Firstly, this paper used TextRank sorting method to extract the keywords in the microblog that user released, and extended this keywords as a tag which represented the user''s interest. Secondly, it formed the list to be recommended according to microblog''s effect function and the life cycle. Finally, it calculated the count of the user''s tag and its synonyms that appeared in the list to be recommended, and recommended the top-k microblog which occurred most frequently to users. Through the experiment, this method could effectively solve the problem of data sparsity of user''s tag and improve the accuracy of the recommendation. |
