为了评价微博的传播效果,在分析影响用户转发行为因素的基础上,提出了采用用户影响力、用户活跃度、兴趣相似度、微博内容重要性和用户亲密程度五项特征进行转发行为预测的SVM算法,以及基于该算法的转发规模预测算法.最后给出了传播规模预测的评价方法.针对新浪微博用户数据的实验表明,预测精度达到了86.63％.%Based on the analysis of the factors that affect retweet behavior,this paper proposed a predict SVM algorithm with five features:user influence,user activity,interest similarity,the importance of micro-blog content and users closeness.Furthermore,it proposed the predict algorithm of retweet scale on the basis of SVM,also,gave a method to evaluate the predict accuracy.The experiment with Sina micro-blog data shows a good result that the predict accuracy is up to 86.63％.
