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 present invention relates to the technical field of network information mining, in particular to a method and device for detecting sudden features of microblogs. Background technique [0002] In recent years, with the rise of the web2.0 social network, Weibo has quickly become popular due to its convenience and speed, and has now developed into the main way of network information dissemination. [0003] Due to its wide range of sources, fast update speed, short transmission cycle, diversified transmission 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 information overload problem, and topic analysis technology can quickly extract the key content of a large amount of information, and compress and organize the massive amount of information. [0004] Weibo topic detection and analysis technolog...
