Abstract

The invention provides a method for filtering garbage users and extracting short text topics. The method carries out garbage user filtering treatment on the original data, largely avoiding the problemthat the detected sudden topic is a topic with no practical significance. Using BTM (Biterm Topic Model) topic model to extract topic, the model is clear and easy to understand, and the efficiency oftopic extraction is high.

Description

technical field [0001] The invention relates to the field of text processing algorithms, more specifically, to a method for filtering junk users and extracting short text topics. Background technique [0002] Emergent topic detection is a popular research direction in the field of network information processing and natural language processing in recent years. Emergent topics are also called emerging topics or trending topics, which generally refer to a class of topics that are about to explode or spread widely. Usually it will be accompanied by major news and hot events. Moreover, the Weibo social networking platform is an open platform, on which information dissemination speed is fast and the dissemination range is wide, and sudden topics may have a significant social impact. Therefore, taking Weibo text as the research object, it is of great theoretical and practical significance to detect topics or events in the data before they evolve into hot events or in the early sta...
