摘　　要：采用社会网络分析与链接分析的方法,从万方机构数据库中检索出部委级专业情报机构,剔除无官网机构,统计这些网站的网页数量、出站链接数量、反向链接数量、PR值,并采用Gephi软件对情报机构网站间的链接关系进行可视化展示,进而对情报机构链接网络结构进行分析。发现中国科学技术信息研究所、机械工业信息研究所、中科院文献情报中心等五所情报机构网站构成的链接网络网络密度、聚类系数比较大,但是网群中存在大量孤立节点群以及链接子网络,网络的整体密度与聚类系数比较小。因此,在专业情报机构间有必要加强交流协作,进而促进科技信息资源的共享,加快科研成果的增值利用。We selected data from the institution database of wanfang,and then removed the professional intelligence agencies having no official website. Based on social network analysis and link analysis,we counted and analysed the number of webpage,outbound links,inbound links and the value of PR. With the Gephi,we visualized and analysed the link relations and the structure of the link network. We found that the network had high density and clustering coefficient,which constituted of five institution such as ISTIC and Machinery industry information institute and Chinese Academy of Science etc. But the whole network＇s density and clustering coefficient are low. As a result,to accelerate the sharing of science resourcs and the utilize of science achievements,it is necessary to strengthen communication and cooperation among information institutions.
