Embodiment Construction

[0021] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Depend on figure 1 Given, the present invention includes microblog sample collection and preprocessing related to specific events, topic probability model generation, and model derivation and parameter design. Microblog sample collection and preprocessing modules are mainly responsible for collecting microblogs related to specific events and participating accounts, segment the microblog content and remove stop words, and judge the emotional polarity of the microblog text; the topic probability model generation module improves the traditional purely topic-oriented LDA model, and integrates the emotional polarity of the microblog account and the forwarding of the microblog Relational factors are added to the model, and community-level modeling is added; the model derivation and parameter design module obtains communities, r...

Abstract

The invention relates to a microblog transmission group division and account activeness evaluation method based on a theme possibility model, aiming at effectively dividing according to transmission groups, dividing accounts participating in microblog topic transmission into a plurality of groups and quantifying active microblog accounts in each group. The method comprises: taking a keyword of a specific accident as the foundation and acquiring microblog specific text information and an account set participating in the microblog transmission; constructing a participating personnel list by text content of each microblog and account set input of the microblog; generating a model of each microblog in a sample library based on a theme probability; sampling words and participating personnel from a constructed word list and the participating personnel list according to group-theme, theme-word and group-human in the model; calculating by adopting a Gibbs sampling method; and adopting a merge sorting method to sort the words under each theme and people in each group. The method provided by the invention is simple and can be used for grasping microblog hot spots, emotional tendencies and public opinion guidance in time.

Description

technical field [0001] The invention relates to the field of microblog public opinion monitoring, in particular to a topic probability model-based microblog propagation group division and account activity evaluation method that automatically divides groups with similar topics in the microblog propagation process based on a topic probability model. Background technique [0002] In recent years, Weibo has become an important medium for netizens to obtain news and current affairs, self-expression and social participation due to its fast and convenient features. It has also become an important platform for social public opinion, corporate brand and product promotion. Topics in Weibo have become the main means for the public to participate in and obtain social focus events, promotion of variety shows and entertainment programs, etc. [0003] Weibo dissemination is a double-edged sword: on the one hand, Weibo provides a platform for rapid response to information disclosure in some...
