Embodiment Construction

[0067] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments described here are only used to explain the present invention, not to limit the present invention.

[0068] Taking three real microblog data sets as examples, the specific implementation method of the present invention is given, and the overall framework of the method is shown in Figure 1. The algorithm flow of the whole system includes three steps: attribute multivariate heterogeneous dialogue network input, learning the embedding of specific views, and topic generation based on multi-view neural variational reasoning.

[0069] Specific steps are as follows:

[0070] (1) Attribute Multivariate Heterogeneous Dialogue Network Input

[0071] On the Sina Weibo platform, the predecessors used the topic index search application programming interface (hashtag-searchAPI) to coll...

Abstract

The invention discloses a microblog topic mining method based on heterogeneous social media user dynamic behaviors, which comprises the following steps: constructing an attribute multivariate heterogeneous dialogue network, and mining heterogeneous social context for topic detection; introducing a neighbor-level attention mechanism and an interaction-level attention mechanism to model different influences of different neighbors and different types of interaction modes on topic inference, and learning embedding of a specific view; the representations of the plurality of views are used as inputsof multi-view neural variational reasoning, and complex associations among topic semantics carried by different views are captured, so that topics with better consistency are mined.

Description

technical field [0001] The invention relates to the technical fields of natural language processing and social media data mining, in particular to a microblog topic mining method based on dynamic behaviors of heterogeneous social media users. Background technique [0002] The emergence of social media sites (such as Sina Weibo, etc.) has greatly changed the form of content on the Internet. Weibo allows users to publish and browse information on it, and has strong social attribute functions, such as forwarding and commenting. A large amount of text data is stored on the Weibo platform, and it grows at an alarming rate every day. Microblog text content contains a large amount of information, mining topic information from it can be used for topic recommendation, emergency detection, precision marketing, etc. At present, text topic mining technology has achieved good results when applied to long text data such as news and articles. However, the length of microblog text is rel...
