【摘要】：隨著網(wǎng)絡信息資源的快速增長,傳統(tǒng)的描述紙質文獻的目錄格式必須加以改進以便適應描述電子資源,元數(shù)據(jù)作為電子資源的描述方式應運而生,越來越得到大家的重視。元數(shù)據(jù)的出現(xiàn)對網(wǎng)絡化信息的存取、數(shù)字圖書館的運用以及搜索引擎性能的提高有重要作用。探索國外元數(shù)據(jù)的研究前沿和研究熱點,對我國元數(shù)據(jù)研究的進一步發(fā)展具有指導意義。 研究前沿是研究過程中出現(xiàn)的潛在研究方向,是研究的新趨勢和新動態(tài)；研究熱點是在某一時間段內,有內在聯(lián)系的、數(shù)量相對較多的一組論文所探討的科學問題或專題。研究前沿和研究熱點代表一個主題領域的發(fā)展方向和研究動態(tài)。把握研究前沿和研究熱點,有助于掌握最新的研究方向,集中優(yōu)勢研究具有發(fā)展?jié)摿Φ男路较�。我國研究人員對元數(shù)據(jù)研究熱點非常關注,已有多篇文章對元數(shù)據(jù)的研究熱點進行了總結,但是對元數(shù)據(jù)研究前沿和研究熱點進行系統(tǒng)性、可視化研究,目前國內外的文獻很少。本文采用CiteSpace這一新的動態(tài)可視化研究方法,結合文獻調研法、引文分析法、聚類分析法等多種方法,探索國外元數(shù)據(jù)的研究前沿和研究熱點。 第一章介紹了國內外元數(shù)據(jù)、信息可視化的研究進展和CiteSpace的使用現(xiàn)狀。首先介紹了國外元數(shù)據(jù)研究進展,同時介紹了中國跟蹤國外的研究熱點情況,以及對中文元數(shù)據(jù)的本土化研究情況。對于國外的信息可視化研究,梳理了信息可視化依托的數(shù)據(jù)庫的建設、信息可視化原理、信息可視化工具以及信息可視化應用研究進展。國內的信息可視化研究主要跟蹤國外的研究,也取得了一定的成就。介紹了CiteSpace軟件國內外的基本使用情況。 第二章介紹了本研究的相關原理方法和數(shù)據(jù)來源。在研究中應用到主要原理包括引文分析原理和信息可視化原理。引文分析原理重點介紹了引文同被引分析理論。信息可視化原理著重介紹了CiteSpace軟件的實現(xiàn)原理以及C iteSpace的三個重要功能。研究方法主要采用文獻調研法、引文分析、聚類分析法等。最后簡要介紹了研究中的數(shù)據(jù)來源。 第三章對國內外元數(shù)據(jù)研究前沿進行了可視化分析。繪制了元數(shù)據(jù)研究領域文獻共被引網(wǎng)絡圖譜�；谶@些圖譜,可以清晰地給出元數(shù)據(jù)的研究前沿,并對研究前沿演化進行了分析。最后通過引文、網(wǎng)絡文獻等資料對關鍵節(jié)點的作用進行了詳細討論,確認了研究前沿及其演化行為。 第四章對國外元數(shù)據(jù)研究熱點進行可視化分析。繪制文獻共被引網(wǎng)絡圖譜和關鍵詞共被引網(wǎng)絡圖譜,對高被引文獻的施引文獻進行二次檢索,再對其施引文獻進行引文共被引網(wǎng)絡聚類圖譜分析,根據(jù)元數(shù)據(jù)領域高頻關鍵詞及高被引論文總結元數(shù)據(jù)的主要研究熱點。最后一節(jié)對國內的元數(shù)據(jù)研究熱點進行了總結,并與本文研究的國外的元數(shù)據(jù)研究熱點進行比較,為我國元數(shù)據(jù)發(fā)展提供建議。
[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.
