中文摘要：

通过对关键词同现网络结构的研究，有助于分析研究领域内的一些关联特征。本文建立了CSSCI收录的2005-2007年情报学领域相关文献的关键词同现网络，使用复杂网络理论方法对该网络拓扑结构和加权结构的网络特性进行了分析，这些网络特性对分析情报学领域的科研特征具有重要参考价值。

英文摘要：

By the research on the structure of key words co-occurrence network, it will help us to analyze some related characteristics in scientific research. In this paper, we take the published research papers in Information Science from CSSCI as an example, construct the key words co-occurrence network from 2005 -2007. We use some theories and methods of the complex network to analyze the Characteristics of topological structure and weighted network. These characteristics have important reference value to analyze the scientific research in Information Science.
