specific Embodiment approach

[0063] On the Sina Weibo platform, people use the "@" symbol to mark and forward or mark people who want to remind to check the message. When the content of “@ID” is included in the microblog published by people, no matter whether it is an original microblog or a reposted microblog, it means that the user (ID) has some kind of connection with the commenter, and the two are related. In particular, for reposting microblogs, since people repost all the previous reposting relationships, for example, user A reposts user B’s original microblog, and user C reposts the microblog reposted by A, then user C’s A repost will contain the IDs of users A and B. Such a transitive relationship may lead to an overly dense relationship network, and will cause many unrelated people to be connected. Therefore, in order to avoid such mistakes, this method only selects the user ID that appears after " / / @" in each forwarded microblog, that is, only records the person with the highest degree of intima...

Embodiment 2

[0072] The user relationship network of Weibo is a relatively stable social relationship system formed by information interaction between Weibo users and users. The information interaction ability indicates the pivotal position of the user in the global relational network structure, which can promote the sharing of network information. As a key node in the user relationship network, opinion leaders are nodes with strong information interaction capabilities. In order to better reflect the global influence of users in the relationship network, it is necessary to measure the user's information interaction ability. The user's global influence calculation includes: node V i and V j represents two different nodes in the network G, and the common neighbor nodes between them are represented by Com(v i ,v j )Expressed as:

[0073] Com(v i ,v j )=Nei(v i )∩Nei(v j )

[0074] where Nei(v i ) and Nei(v j ) represent node V respectively i and V j all neighbor nodes of . This...

Abstract

The invention discloses an opinion leader identification method and system based on user comprehensive influence, and the method comprises the construction of a microblog user relation network, and mainly comprises two steps: firstly, carrying out the data collection of a concerned topic through a python crawler, and carrying out the data preprocessing; secondly, according to the finally obtained user and the relationship thereof, importing Gephi to carry out visualization of a user network; calculating the global influence of the user and the local influence of the user according to the user relation network; and finally, obtaining an influence sequence of the users. Wherein the influence of one user should be measured by comprehensively considering the close degree of the user and other users and the influence of the nearest neighbor user, namely, the influence of the user is measured by fusing a global structure and a local structure; according to the method, the difference of global and local influences of opinion leaders can be reflected, so that more targeted suggestions are provided for public opinion monitoring and guiding under different topics.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a microblog opinion leader identification method based on comprehensive influence of users. Background technique [0002] With the vigorous development of social networks, the influence of users in social networks has gradually attracted people's attention. The current research directions related to social influence mainly include finding opinion leaders and influence communication. The strength of social influence can be observed through the social activities among users, and the specific performance is that users with great influence can change the behavior and thinking of other users. Opinion leaders can not only trigger and sustain issues, but also change the direction of public opinion by influencing the attitudes of other netizens. Accurate identification of opinion leaders is of great significance to guide netizens' opinions and effectively manage public opinion. In ...
