国外数字图书馆研究进展:基于关键词共现和文献共被引的可视化研究

Foreign Research Progress of Digital Library Based on Co-word and Document Co-citation Visualization Analysis

以ISI的Web of Science为数据源,借助文献计量学方法,从文献的学科分布、国家/地区分布、作者分布和基金资助分布等方面,对国外2008年-2011年间有关数字图书馆研究的相关论文进行统计与分析。同时采用关键词共现和文献共被引分析方法,借助CiteSpaceⅡ对文献的关键词和参考文献进行可视化分析,发现国外数字图书馆研究以借助相关计算机技术提供用户个性化、易用性服务为核心研究内容,并将成为持续研究热点,具体研究热点包括:基于本体、语义web的数字图书馆信息检索、数字图书馆系统设计、数字图书馆可用性评价、数字图书馆模型、数字图书馆个性化协同服务等。

In order to follow the progress of the foreign digital library research, published articles on digital library during 2008 - 2011, which are recorded in the database of IS! Web of Science, are chosen to be analyzed in this paper. By applying the method of bibliometric, this paper mainly dis- cusses the distribution of disciplines, countries/area, authors and fund assistance. Meanwhile, through co - word, document co - citation analysis and application of CiteSpaceII, this paper analy- zes the related keywords and references by visualization method. The study finds that the digital li- brary research put emphasis on the personalized and accessible services by adopting related computer technology, which will continue to be the research focuses, including： the information retrieval of digital library based on ontology and semantic web, digital library systems design, digital library ac- cessibility evaluation, digital library model and personalized collaborative digital library.
