Abstract

The invention relates to the technical field of topic detection, and discloses a microblog topic detecting method and system. The method comprises the following steps: S1, segmenting a microblog text into vocabularies; S2, constructing a microblog text clue and a microblog text forest; S3, analyzing a microblog topic aiming at a specific microblog text clue so as to find out the main topic and noise topic in the microblog text clue; S4, combining the microblog text in the main topic aiming at each microblog text clue, thereby generating a microblog clue text for each microblog text clue; and S5, analyzing overall microblog topics to detect an overall microblog topic, thus forming a microblog topic base. The microblog topic detecting method and system can be used for rapidly and accurately detecting the microblog topic, thereby improving the hit rate of the microblog search, shortening the microblog search time of a user and improving the user experience.
