【摘要】：随着网络信息资源的快速增长,传统的描述纸质文献的目录格式必须加以改进以便适应描述电子资源,元数据作为电子资源的描述方式应运而生,越来越得到大家的重视。元数据的出现对网络化信息的存取、数字图书馆的运用以及搜索引擎性能的提高有重要作用。探索国外元数据的研究前沿和研究热点,对我国元数据研究的进一步发展具有指导意义。研究前沿是研究过程中出现的潜在研究方向,是研究的新趋势和新动态；研究热点是在某一时间段内,有内在联系的、数量相对较多的一组论文所探讨的科学问题或专题。研究前沿和研究热点代表一个主题领域的发展方向和研究动态。把握研究前沿和研究热点,有助于掌握最新的研究方向,集中优势研究具有发展潜力的新方向。我国研究人员对元数据研究热点非常关注,已有多篇文章对元数据的研究热点进行了总结,但是对元数据研究前沿和研究热点进行系统性、可视化研究,目前国内外的文献很少。本文采用CiteSpace这一新的动态可视化研究方法,结合文献调研法、引文分析法、聚类分析法等多种方法,探索国外元数据的研究前沿和研究热点。第一章介绍了国内外元数据、信息可视化的研究进展和CiteSpace的使用现状。首先介绍了国外元数据研究进展,同时介绍了中国跟踪国外的研究热点情况,以及对中文元数据的本土化研究情况。对于国外的信息可视化研究,梳理了信息可视化依托的数据库的建设、信息可视化原理、信息可视化工具以及信息可视化应用研究进展。国内的信息可视化研究主要跟踪国外的研究,也取得了一定的成就。介绍了CiteSpace软件国内外的基本使用情况。第二章介绍了本研究的相关原理方法和数据来源。在研究中应用到主要原理包括引文分析原理和信息可视化原理。引文分析原理重点介绍了引文同被引分析理论。信息可视化原理着重介绍了CiteSpace软件的实现原理以及C iteSpace的三个重要功能。研究方法主要采用文献调研法、引文分析、聚类分析法等。最后简要介绍了研究中的数据来源。第三章对国内外元数据研究前沿进行了可视化分析。绘制了元数据研究领域文献共被引网络图谱。基于这些图谱,可以清晰地给出元数据的研究前沿,并对研究前沿演化进行了分析。最后通过引文、网络文献等资料对关键节点的作用进行了详细讨论,确认了研究前沿及其演化行为。第四章对国外元数据研究热点进行可视化分析。绘制文献共被引网络图谱和关键词共被引网络图谱,对高被引文献的施引文献进行二次检索,再对其施引文献进行引文共被引网络聚类图谱分析,根据元数据领域高频关键词及高被引论文总结元数据的主要研究热点。最后一节对国内的元数据研究热点进行了总结,并与本文研究的国外的元数据研究热点进行比较,为我国元数据发展提供建议。
[Abstract]:With the rapid growth of network information resources, the traditional cataloguing format for describing paper documents must be improved to adapt to the description of electronic resources. Metadata as a way of describing electronic resources came into being, and more and more attention has been paid to it.The appearance of metadata plays an important role in the access of network information, the application of digital library and the improvement of search engine performance.Exploring the research frontier and research hotspot of foreign metadata is of guiding significance to the further development of metadata research in China.The research frontier is a potential research direction, a new trend and a new development in the research process, and the research hotspot is a group of scientific problems or topics discussed by a relatively large number of papers in a certain period of time.The research frontier and research hotspot represent the development direction and research trend of a subject field.Grasping the research frontier and research hotspot is helpful to grasp the latest research direction and to concentrate on the new research direction with development potential.Researchers in our country pay great attention to the research hotspot of metadata. Many articles have summarized the research hotspot of metadata, but the research frontier and research hotspot of metadata are studied systematically and visually.There is little literature at home and abroad at present.In this paper, CiteSpace, a new dynamic visualization method, is used to explore the research frontier and research hotspot of foreign metadata, including literature research, citation analysis, clustering analysis and so on.The first chapter introduces the research progress of metadata, information visualization and the use of CiteSpace at home and abroad.This paper first introduces the research progress of foreign metadata, at the same time introduces the hot research situation of Chinese metadata tracking abroad, and the localization of Chinese metadata.For the research of information visualization abroad, this paper reviews the construction of database based on information visualization, the principle of information visualization, the tools of information visualization and the research progress of information visualization applications.The domestic information visualization research mainly tracks the foreign research, also has obtained the certain achievement.This paper introduces the basic usage of CiteSpace software at home and abroad.The second chapter introduces the principle, method and data source of this study.The main principles applied in the research include the principle of citation analysis and the principle of information visualization.The principle of citation analysis focuses on the theory of citation and citation analysis.The principle of information visualization mainly introduces the realization principle of CiteSpace software and three important functions of C iteSpace.The research methods are mainly literature research, citation analysis, cluster analysis and so on.Finally, the data sources in the research are briefly introduced.The third chapter analyzes the frontier of metadata research at home and abroad.The citation network map of the literature in the field of metadata research is drawn.Based on these maps, the research frontier of metadata can be clearly given and the evolution of the research frontier can be analyzed.Finally, the role of key nodes is discussed in detail by citation, network literature and so on, and the research frontier and its evolution behavior are confirmed.The fourth chapter analyzes the foreign metadata research hotspots visually.The citation network atlas and keyword co-citation network atlas were drawn, the citation literatures of high citation documents were searched twice, and the citation cocitation network cluster atlas of the cited documents were analyzed.According to the high-frequency keywords and high-cited metadata in the field of metadata, this paper summarizes the main research hotspots.In the last section, the domestic metadata research hotspots are summarized and compared with the foreign metadata research hotspots in this paper, which provide suggestions for the development of metadata in China.
