Abstract

Due to the difficulty to apply traditional method that extracted semantic relations between terms to microblog, which made hot event detection not sensitive, this paper proposed a new method based on semantic co-occurrence of terms and community partition to find hot events. First, it utilized the defined hotness to filter micro-blog data initially, then combined TF-IDF formula with semantic relationships between items calculated by computing affinity score between two adjacent nodes on graph to harvest semantic relevancy. Next, it introduced the idea of community partition to design the algorithm for word clustering, which obtained a series of microblog hot events finally. Experimental results show the effectiveness of the proposed method. Compared with the kindred methods, this method has a higher accuracy, and the found hot event is consistent with the real-time event basically.
