With the rapid development of online education, virtual learning community has a great impact on people's learning. Here we focus on the dynamics evolution law of collaborative behavior, characterizing the features of collaborative behaviors among learners in virtual learning community. We construct a learners' collaboration network model in virtual learning community. We analyze important statistics of the network such as the degree distribution, the average path length, the clustering coefficients. On this basis, we describe the network features and study the topology characteristics of the ...
