国内元数据研究共词图谱分析

Co-word Mapping Analysis of Domestic Metadata Research

在确定2003年以来国内元数据领域64个关键词的基础上,运用共词图谱分析方法,通过绘制聚类图、战略坐标图、社会网络图探究了国内元数据领域的研究结构、研究热点及发展趋势。结果表明国内元数据研究主要集中在空间元数据、电子政务中元数据的应用、元数据标准、电子文件管理元数据等七个方面,而元数据管理、元数据模型和基于Web服务的元数据应用等将会成为未来研究趋势。

On the basis of identifying 64 keywords in domestic research in the metadata field since 2003, this paper explores the struc- tures, hotspots and developing trends of the research using co-word mapping analysis by drawing clustering map, strategic diagram and network diagram. The result shows that the research focuses mostly on seven aspects including spatial metadata, application of metadata in e-government, metadata standard, and electronic document management metadata etc. Moreover, future research development will go a- round metadata management, metadata model, and metadata application based on web service etc.
