| 摘 要： | 论坛中"意见领袖"的自动发现对于我们掌握舆情,及时引导舆论有重要作用.为此设计了一个从论坛中自动发现意见领袖的算法.根据构成意见领袖的基本属性,设计了基于贝叶斯信息增益最大化准则的X-means迭代聚类筛选模型,然后利用该模型找到特征空间中的意见领袖特征点.实验表明,应用该模型的算法在发现意见领袖的查全率,查准率方面性能优越,可以有效实现网络舆情监控.

| Abstract: | Detection ofopinion leadersautomatically in BBS is significant for us to grasp and guide the public opinion in time.Consequently,we proposed an algorithm which can detect theopinion leadersin BBS automatically.After analyzing the essential attributes ofopinion leaders,a X-means iteration clustering filter model based on the Bayesian information gain maximization formula was proposed to find out the opinion leader feature points in the feature space.The experiment shows that the algorithm based on the model ... |
