Abstract
[Purpose/Significance] The rapid growth of micro-blog users and the popularity of mobile Internet make Micro-blog an increasingly important channel for information dissemination. As a result of shortening the distance between ordinary users and opinion leaders, opinion leaders on the micro-blog platform have become more prominent. Therefore, it is very important to identify opinion leaders in micro-blog and study their role in the process of information dissemination. [Method/Process] This article first identifies opinion leaders through the improved HITS algorithm; Then build opinion leader network to analyze the role of opinion leader in the process of information dissemination; Finally, using emotion recognition technology, the ability of opinion leaders to infect other users is analyzed in depth. [Result/Conclusion] The study found that the role of media users as a source of information was weakened in micro-blog platforms, but that media opinion leaders were involved in topics and information dissemination capabilities were stronger. The authority of users is more related to the quality of information, and many users with fewer fans can also become opinion leaders. In terms of degree distribution, no user can have a high monopoly on authoritative information sources. But the channel of information dissemination is more concentrated, and the channel of communication of a topic is often controlled by a few users. Through emotional recognition analysis of the appeal of opinion leaders, it was found that other users tend to be more inclined to non-negative emotions when forwarding opinion leaders 'microblogs. The appeal of opinion leaders is generally strong.
