本研究分別利用書目對分析與共被引分析的方法，以資訊科學重要期刊之高引用期刊、作者與高被引期刊、作者作為研究對象，建構1991年至2010年之資訊科學知識地圖與研究前鋒。知識地圖的建構，採用文獻內容探勘工具(Content Analysis Toolkit for Academic Research，簡稱CATAR)作為分析工具，利用Web of Science下載書目資料，進行期刊與作者之書目對分析，以了解資訊科學高引用期刊與作者的叢集情況，進而探討資訊科學的知識結構。研究前鋒的建構則是透過Web of Science檢索共被引分析之數據，了解高被引期刊與作者之叢集情形，進而探討資訊科學之核心議題。 研究結果歸納如下： 一、資訊科學領域主要分成圖書資訊學與電腦科學兩大範疇。 二、資訊科學領域有跨學科之性質，許多期刊與作者研究的範圍不限於資訊科學領域，還包括了電腦科學、心理學、管理學、語言學、歷史學等。 三、資訊科學領域的共被引次數普遍偏低。 四、資訊科學領域核心議題的主要範圍為圖書資訊學、電腦科學、資訊科技與管理領域，子主題包含線上資訊、資訊檢索、資訊尋求行為、人機互動、自動化分類索引、書目計量學、科學計量學、網路計量學、引用文獻分析、研究前鋒研究、資訊視覺化、數位圖書館、資訊素養、圖書館服務、學術圖書館、科學計量學、電腦工程、電腦通訊、網際網路、資訊科技、資訊系統、管理。 五、1991年到2010年間，圖書館與資訊服務的自動化和資料庫設計與管理這兩個主題，在資訊科學領域中漸漸式微。 本研究結果可看出資訊科學的知識結構與研究前鋒，可應用於館藏規劃與評估，檢視圖書館的資訊科學領域館藏是否完整，並提供資訊科學領域的學者觀察學術研究趨勢之用。 / Through bibliographic coupling and co-citation analysis, this study builds on the knowledge map and research front of information science fields from 1991 to 2010. First, this research use CATAR which based on journal bibliographic coupling analysis and author bibliographic coupling to analyze the high citing journal and author in information science, and plot knowledge map on the subject of Information Science. Second, this research use journal co-citation analysis and author co-citation analysis where journal and author citing co-citation clusters to build the research front of Information Science. To result of the study reveal that： 1. Library and Information Science, Computer Science are the main disciplines in Information Science area. 2. The field of Information Science has the nature of interdisciplinary. The research area of any journals and authors are not limited to Information Science, and even likely to go beyond the subject of other disciplines, such as: Computer Science, Psychology, Management, Linguistics, History, etc. 3. Co-citation frequencies of Information Science high cited journals and authors are low. 4. The core area of Information Science field is Library and Information Science, Computer Science, Information Technology and Management. 5. During 1991 to 2010, library and information service automation, and design and management of database have been declining.

近年來各國因應數位化的發展，加上資訊技術應用於教與學已經是全球的趨勢，各國紛紛將數位學習的推動列為國家重要政策，對數位學習領域主題研究之發展極為重視。為了幫助研究人員更精確掌握數位學習領域的研究脈動，有必要針對數位學習領域發表之期刊文獻進行全面性的計量以及主題內容分析。 本研究採廣義數位學習定義之檢索策略，蒐集2000年至2009年間合計2,125篇數位學習領域SSCI期刊文獻，針對這些文獻以自動化內容探勘工具CATAR進行全面性計量分析，再分別以共現字及書目對進行研究主題分析，以藉此歸納數位學習領域的研究主題架構。此外，本研究亦將經由共現字與書目對歸類所獲得之主題架構，與Computers & Education (C&E)專家分類之主題架構進行相互的參照與比對，以歸納出更為完備的數位學習領域研究主題架構。 本研究歸納獲得之數位學習領域研究主題架構，可幫助研究人員檢視自己的領域專長、掌握數位學習各研究主題面向發展狀況以及作為學者專家選定研究主題之參考；此外，透過文獻計量分析所得之國際間數位學習領域最具生產力作者、最具競爭力機構、最具影響力國家、高被引用期刊文獻、較具代表性研究主題發展趨勢以及數位學習跨領域整體學術研究發展概況等，有助於研究人員瞭解目前整個國際間數位學習領域的研究發展現況。 / With the digital development and the global trend of information technology applying teaching and learning in recent years, every country around the world regards the promotion of e-learning as a very important policy of the country. They lay special emphasis on the development of the subjects of study in e-learning. In order to help the researchers to predominate more precisely about the study of e-learning field, it is necessary for us to carry out the comprehensive calculation and subject context analysis toward the published periodical literature in connection with the e-learning field. The present study adopts the search strategy of generalized definition of e-learning and collects 2,125 SSCI periodical literature in total on e-learning field from the years of 2000 till 2009. They are analyzed with automatic context exploration tool CATAR to proceed to the general bibliometric analysis. Then they are analyzed with co-occurrence words and bibliography coupling to proceed to the study subject analysis. Thus it can generalize the frames of study subjects of e-learning field. In addition, the present study will carry on the interactive reference and contrast through the subject frames by the co-occurrence words and bibliography coupling with the subject frames classified by Computers & Education (C & E) experts to figure out more complete frames of study subject in e-learning field. The present study can help researchers examine their own field specialty, master the dimensions of the development of study subjects and make reference to the scholars and experts to determine their study subjects. Furthermore, it can help the researchers understand the development status of international e-learning field at present with the most productive author, the most competitive organization, the most influential country, the most adoptive periodical document, the more representative trend of development of study subject and the study development status of e-learning interdisciplinary field overall academic research through literature bibliometric analysis.
