資訊需求及資訊尋求 研究文獻特性之比較: 書目計量及社會網絡分析 A Comparative Study of the Research Literature on Information Needs and Information Seeking: A bibliometric and social network analysis

本研究目的在以書目計量法及社會網絡分析法分析及比較1962至2009年有關資訊需求及資訊尋求二個主題研究論文之特性,包括論文的數量分布、作者數量分布、學科分布、國家合作及高被引文獻。研究結果顯示資訊需求及資訊需求二個主題之期刊論文均自1991年起明顯增加,且各有七成是合著論文,但國際合著論文數量僅占全部8%,另多數高產量作者亦是最重要的中心作者,以及資訊需求及資訊尋求均為跨學科研究主題,但資訊需求期刊論文集中在醫學領域,而資訊尋求論文集中在圖書資訊學領域。 This paper aimed to use bibliometrics and social network analysis to compare the characteristics of research articles on information needs and information seeking published from 1962 to 2009. The results found that both the number of information needs journal articles and information seeking journal articles has been obviously rising since 1991. About 70 percent of journal articles on information needs and information seeking are coauthored papers, respectively. Only about 8 percent of journal articles are coauthored by researchers from different countries. Most of the top 10 prolific authors are also the top 10 coauthors with the highest betweenness centrality. Related studies on information needs and information seeking could be found across many disciplines. Among them, most articles on information needs published in journals of medicine, while most articles on information seeking published in journals of library and information science.
