【摘要】：微博是当前最具有影响力的在线社交平台之一,也是社交网络领域热门的研究对象。其中,微博社区分析与微博权威人物的研究是一个社交网络研究的热点。但是,现有的权威人物挖掘没有充分体现权威人物的领域特性,即不同领域权威人物不同,微博大V和领域权威是两个概念。因此,本文围绕自动从海量微博中挖掘不同领域的权威人物展开。面向领域的权威用户排名具有两重性,不仅需要基于领域文本内容,也需要结合网络行为分析。本文以新浪微博为研究对象,在领域词典的基础上,分析用户微博内容以及领域用户关系图,提出了领域微博权威性用户度量模型DMAURM (Domain-Oriented Microblog Authoritative User Ranking Model)。在海量新浪微博数据以及多个领域上的实验结果表明,本算法与用户平均转发数排名和粉丝数排名进行对比,有效地降低了粉丝数目的过大影响,能更有效地找出相关领域内的权威用户。在上述度量模型基础上,实现了一个领域的微博用户权威性分析系统,用户在选择特定领域之后,系统将自动得到领域权威人物,以及权威人物最近在本领域中发布的相关微博。该系统被集成到协作企业的行业咨询门户中。
[Abstract]:Weibo is one of the most influential online social platforms, and it is also a hot research object in the field of social networks. Among them, the research of Weibo community analysis and Weibo authorities is a hot spot of social network research. However, the existing mining of authoritative figures does not fully reflect the domain characteristics of authoritative characters, that is, different domain authority figures are different, Weibo large V and domain authority are two concepts. Therefore, this paper focuses on the automatic mining of authority figures in different fields from massive Weibo. Domain-oriented authoritative user ranking has dual character, which needs not only domain text content, but also network behavior analysis. This paper takes Sina Weibo as the research object, based on the domain dictionary, analyzes the user Weibo content and domain user relationship diagram, and puts forward the domain Weibo authoritative user metric model DMAURM / Domain-Oriented Microblog Authoritative User Ranking Modeler. The experimental results in massive Sina Weibo data and in many fields show that the algorithm can effectively reduce the excessive influence of the number of followers by comparing with the average number of users forwarding ranking and the number of fans ranking. Can find the authority user in the relevant domain more effectively. On the basis of the above measurement model, a domain Weibo user authority analysis system is implemented. After the user selects a specific domain, the system will automatically get the domain authority. And the relevant Weibo that authority personage recently releases in this field. The system is integrated into the industry consulting portal of collaborative enterprises.
