考虑多交互关系与情感倾向的微博用户可信度评估算法
Microblog users'credibility evaluation algorithm considering multi-interaction relationships and emotional tendencies
摘要
Abstract
This paper proposed a new algorithm of the credibility evaluation concerning microblog users,based on their multi-ple interactive relationships and emotional tendencies.Firstly,the algorithm calculated the interaction degree and participation degree of users by analyzing the types and frequency of interactions among users.Secondly,this algorithm made the emotional scores of the textual contents including comments and replied among users by using a sentiment dictionary,and assessed users'emotional tendencies.Thirdly,based on the PageRank algorithm,the new algorithm extracted the features from user profiles and blog posts in order to compute the initial PageRank value for representing individual user credibility,adjusted the distribution of PageRank weights by integrating the user interaction degree and emotional tendencies,and modified the damping factor in ac-cordance with the participation degree.Finally,the proposed algorithm made the credibility of the evaluated users after the iter-ative stabilization.The experimental results show that,compared to methods that overlook multi-interaction relationships and emotional tendencies,the new algorithm achieves better results with an improvement of up to 13.86％in terms of AUC value,precision,recall,and F1-measure.The method that considers multiple interaction relationships and emotional tendencies can enhance the effectiveness of microblog user credibility evaluation with respect to microblog users.关键词
