Localization of information on communication networks of an open-source online community

摘要

In order to study the information communication ability (i.e. information conductivity) of CodePlex C# community, an Open-Source Online Community (OSOC), we first construct the models of weighted communication networks in 11 periods for the community based on large-scale data collections. Then by using two ways of quantum mapping of complex networks, we analyze the localization properties of information on the maximum connected graphs (named as communication networks) of these weighted networks according to the idea of analyzing the localization properties of an electron on a large cluster. We draw the following conclusions. (1) CodePlex C# OSOC usually has information isolativity. (2) The community has some degree of information communication ability and the ability increases as time goes on. (3) The localization of information on the communication networks in any period induced by its structure is weaker than that induced by its structure together with the connection intensities between its nodes. (4) Our idea and methods can be used to analyze the information communication ability of other online communities.
