The knowledge structure of a discipline can be expressed by a co-word network. Six types of evolution of community are recognized, which are birth, death, splitting, merging, growth, and contraction. A topic evolution analysis framework is created based on Z-value mechanism and community match mechanism. Comparing with the traditional methods, the method proposed in this paper focus on the links between words rather than the frequency of words, which is a innovation in the field of ETD from the mesoscopical network view.
