Abstract

The present invention provides a grouping method and system based on core group mining and opinion leader identification results, including: spreading network users into opinion leaders, de-intersecting core groups, and other users; constructing a layered spreading network model, with nodes of the above three categories In the user, the propagation behavior between users is used as the path between the corresponding nodes; the different comprehensive index values ​​of the different propagation directions of the users in the middle layer and the bottom layer are obtained through the number of propagation behaviors, and the de-intersection core group-comprehensive index value table is constructed and other users-comprehensive index value table; opinion leaders are divided into credible opinion leaders and untrustworthy opinion leaders; users within the de-intersection core group and other users are divided according to the de-intersection core group-comprehensive index value table and other users-comprehensive The index value table is grouped. The above method and system make full use of the results of core group mining and opinion leader identification to implement user grading based on event participation.

Description

technical field [0001] The present invention relates to the technical field of data mining and the field of social network analysis, and more specifically, to a grouping method and system based on core group mining and opinion leader identification results. Background technique [0002] Nowadays, Sina Weibo has a large number of active users and rich speeches, which makes social network analysis based on Sina Weibo data more and more important. It is precisely because of the surge in user participation that how to measure the degree of participation of many users and classify them has practical application significance for platform supervision and key event monitoring. In the existing research, whether it is mining the core group in the community grouping results or identifying opinion leaders in the communication network, there have been many related researches and improved methods. However, there are very few studies on the classification of participants in the communicat...
