Abstract

The invention provides a microblog hot topic detection method and apparatus and relates to the technical field of network information digging. Difficulty for detection of hot topics of highly-sparse microblog texts can be eliminated. The method comprises steps of extracting meaningful strings in an information flow and conducting heat analysis to the meaning string to screen hotspot features, combining hotspot features according to information bottleneck theory, calculating combining degree indication parameters after the combination, and determining the hot topic based on the combining degree indication parameters.

Description

technical field [0001] The invention relates to the technical field of network information mining, in particular to a burst feature detection method and device for microblogs. Background technique [0002] In recent years, with the rise of web2.0 social network, microblog has become popular rapidly due to its advantages of convenience and quickness, and now it has developed into the main way of network information dissemination. [0003] Due to the characteristics of wide sources, fast update speed, short communication cycle, diversified communication methods, strong participation and interaction, Weibo has achieved strong influence and guidance in the formation and dissemination of hot topics. The amount of microblog information is large, and there is a serious problem of information overload, and the topic analysis technology can quickly extract the key content of a large amount of information, and compress and organize the massive information. [0004] Microblog topic de...
