An Evolutionary Model of Reply Networks on Bulletin Board System

In order to study the relation between structure and behaviors of networks, an evolutionary model of reply networks on Bulletin Board System (BBS) is proposed in this paper. With the theories of scale-free model, we built the Barabási-Albert (BA) model on the directed network for the characteristics of reply network. Comparing the results of BA model with the virtual data, there exists a deep gap between them, and a new model will be proposed to narrow the gap under the deeply analysis of the reply network on BBS. The new model is closer to real network than BA model, but the gap is just narrower not disappear, so how to fill the gap is our next job.
