Study of Topic Life Cycle Based on Hierarchical HMM

Abstract:

This paper presents a topic ontology tree based hierarchical HMM (hHMM), and the generation of topic property based life cycle curve is studied. Compared with the traditional methods, this model can describe the hierarchy relations of topics.
