Problems solved by technology

[0004] Previous studies did not take these three influencing factors into consideration. The user influence model takes these three aspects into consideration, and assigns different weights to reflect the importance of different factors, which can more accurately measure user influence.

Embodiment Construction

[0088] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0089] refer to figure 1 , the present invention is oriented to the method for measuring user influence at the topic level of microblog, and is implemented according to the following steps:

[0090] Step 1: Microblog text similarity calculation

[0091] The traditional text clustering technology mainly uses Vector Space Model (Vector Space Model, VSM) to calculate the similarity between texts, which calculates the similarity between texts by counting the word frequency of documents, but the premise of this method is to assume The words are independent of each other, and the content of the document is not analyzed semantically, so the similarity between documents cannot be accurately calculated, thereby affecting the clustering effect. The research object of the present invention is a microblog text, which is a network short text with a maxi...

Abstract

The invention discloses a method for measuring the influence of users on the topic hierarchy for MicroBlog. The method comprises the steps of 1, calculating the similarity of MicroBlog texts; 2, obtaining a topic set according to the dynamic clustering algorithm correlation; 3, measuring the influence of the users on the topic hierarchy according to standards: calculating the information propagation influence of the users, calculating the MicroBlog value influence of the users and calculating the activeness influence of the users; 4, establishing a user influence measurement model. According to the method, the effects of the three factors of information propagation, user activeness and user MicroBlog value on the influence of the users are comprehensively considered, the user influence measurement model is established, the influence of the users on the topic hierarchy can be measured more accurately through the model, then the users playing a key role in the topic propagation can be found, and public opinion monitoring and tracing in the MicroBlog network have the guaranteeing and monitoring effects.

Description

technical field [0001] The invention belongs to the technical field of network public opinion analysis, and relates to a topic-level user influence measurement method, in particular to a microblog-oriented topic-level user influence measurement method. Background technique [0002] Timely access to sensitive topics on Weibo and reduce the adverse effects of further dissemination, discover users who play a key role in topic dissemination, and guide these key users to correctly guide the direction of public opinion, which has become a new network The media and public opinion supervision department urgently needs to solve the problem. [0003] At present, research on the influence of microblog users at home and abroad mainly has the following directions: research on influence based on individual attributes, research on influence based on network structure, research on influence combined with individual attributes and network relationships, and research on influence at the level...
