中文摘要：
针对目前基于单一维度构建微博用户兴趣模型导致微博用户关注推荐有效性不高的现状,本文从微博用户属性、关键词及微博用户行为等三个维度构建了微博用户兴趣模型,提出了基于向量空间模型余弦值算法的微博用户兴趣相似度计算方法。最后,通过新浪微博数据进行模拟实验,验证了模型的有效性。
英文摘要：
According to the present situation that the low efficiency of the microblog user following recom-mendation which result from single dimension building of the microblog user interest model. This paperbuilt the microblog user interest model from the three aspects of user attributes, keywords and user behav-ior, and proposed microblog user interest similarity calculation method which based on vector space mod-el cosine algorithm. In the end, the paper conducted simulation experiment based on the data of sina mi-croblog, then verified the validity of the model.
