摘要： 以论文关键词为研究对象，建立一个加权网络模型，通过理论分析和仿真结果验证网络模型的度分布和点强度分布符合幂律分布，同时发现网络具有较大的聚集系数和明显的社团结构。为了验证其有效性，对2004年1月至2008年10月期间发表在《软件学报》上的论文关键词进行统计、分析并与仿真模型进行对比，结果表明理论分析结果与实证数据结果一致。

Abstract: A weighted network model is constructed as the keywords for objects study, by theoretical analyzing and simulation results validating, the degree distribution and strength distribution of the network model obey paw-law distribution. At the same time, the network has big cluster coefficient and distinct community structure. To prove its efficiency, it makes statistics and analysis on keywords of research papers published in "Journal of Software" from January 2004 to October 2008, and comparison with the simulation model. The results show that the theoretical results of the analysis are consistent with the empirical data.

Key words: complex network, research cooperation, weighted network
