Embodiment Construction

[0062] Embodiments of the present invention include the following steps:

[0063] Step 1 extracts microblog multimodal features (Feature Extraction), the specific method is as follows:

[0064] Step 1.1 For the text mode, first use the automatic word segmentation tool ICTCLAS of the Chinese Academy of Sciences to segment the microblog text content (Text segment), and then use the processed Chinese sentiment dictionary (Text word dictionary) to construct words for each microblog text after word segmentation Bag-of-textual-word, as the text sentiment feature after the final screening, the Chinese sentiment dictionary is composed of HowNet Chinese sentiment dictionary and National Taiwan University NTUSD Chinese sentiment dictionary, and screened out text corpus in Weibo The 2547 emotional words with higher frequency appearing in the Chinese emotional dictionary are composed of them. The i-th microblog text feature is denoted as F i botw ;

[0065] Step 1.2 For the visual mod...

Abstract

The invention provides a microblog emotion prediction method based on multi-mode hypergraph learning and belongs to the field of multi-mode emotion analysis. The microblog emotion prediction method based on multi-mode hypergraph learning is provided aiming at the problems existing in emotion prediction on microblog multi-channel content. The method includes the following steps that 1, microblog multi-mode features are extracted; 2, the distance between microblog is calculated; 3, a multi-mode hypergraph model is established; 4, hypergraph learning is carried out. Different modes can be better associated to solve the problem of independence between the modes, and a good effect is achieved on microblog emotion prediction.

Description

technical field [0001] The invention belongs to the field of multimodal emotion analysis, and in particular relates to a microblog emotion prediction method based on multimodal hypergraph learning. Background technique [0002] Recently, with the rapid development of large social platforms such as Sina Weibo, the scale of multimedia data in social networks is increasing every day. Taking Sina Weibo as an example, as of May 2014, the monthly active users of Sina Weibo reached 140 million. It was up 10.9% in December 2013. As one of the most popular platforms, Sina Weibo enables Internet users to express their emotions on topics of interest to them. Therefore, it has attracted a large amount of research on emotional information mining, which involves some emerging applications including event detection, social network analysis, and business recommendation. [0003] An obvious feature of the development of Weibo is the growth of multimodal information, such as images, videos,...
