Hot Topic Detection Based on a Refined TF-IDF Algorithm
In this paper, we propose a refined term frequency inversed document frequency (TF-IDF) algorithm called TA TF-IDF to find hot terms, based on time distribution information and user attention. We also put forward a method to generate new terms and combined terms, which are split by the Chinese word...
