Hierarchy Topic Detection and Hot Topic Identification
Xue Mei Zhou, Shan Ying Cheng · Applied Mechanics and Materials · 2014
Due to the problem that the existing topic detection algorithms can not satisfy accuracy,real time and topic hierarchical clustering at the same time, this article builds a hierarchy topic detection algorithm based on improved single pass clustering algorithm. In addition, using public opinion evaluation indexes to analyze topic temperature,the method proposed in this paper can detect hot topics accurately and timely while showing the hierarchical structure of the topic .
