数据挖掘领域的科研合作网络分析

Research Cooperation Networks in Data Mining

基于SCI和SSCI数据库中以"数据挖掘"为主题的文献题录信息,构建三个科研合作网络(高校间、公司间、国家间),利用社会网络分析方法对这三个不同类型的网络特征进行对比分析。结果显示,数据挖掘领域的研究成果涉及众多研究方向,不同的机构实体有不同的研究重点,所构建的三个不同类型的科研合作网络在诸多网络特征上存在较大的差异,包括合作网络的密度、节点的平均度、最大成分的平均最短路径、最大成分的比重等。最后对部分高校与公司的研究重点进行具体分析。

Based on bibliographic information of ＂data mining＂ in the SCI and SSCI database,the authors construct three kinds of cooperation networks（inter-university,inter-company,inter-country）,compare and analyze the characteristics of the three different networks by using social network analysis method.The results indicate that the researches in data mining involve in many areas,different research agencies focus on different contents,and the three kinds of cooperation networks show different network characteristics,including the density of network,the average node degree,the average shortest path of the largest component,the proportion of the largest component,etc.The authors also analyze the research focus of some universities and companies specifically.
