Abstract

The invention discloses a method and device for automatic detection of microblog hot topics, relating to the technical field of internet. According to the invention, key words are extracted from a to-be-detected microblog text, then key terms are acquired, next, the key terms are clustered, so that candidate key word clusters are obtained; finally, the concern degree of the topic corresponding to each candidate key word cluster is computed, and the hot topics are selected according to the concern degrees. Through adoption of the method and device, hot topic detection becomes simple and the hot topics can be detected effectively.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for automatic detection of microblog hot topics. Background technique [0002] With the rapid expansion of the user groups of Twitter and Sina Weibo, short messages generated by users have also shown explosive growth, and the timeliness of information has become stronger and stronger. It is no longer possible to understand current hot events by browsing each message accomplish. Existing microblog hot topic detection methods usually adopt methods based on semantic extension. This method aims at the characteristics of short microblog messages and relatively few feature words that can be extracted, and expands the dimension of feature vectors through semantic correlation to improve the accuracy of similarity calculation between short texts, thereby improving the accuracy of hot topics in microblogs. detection effect. [0003] However, for methods based on...
