【摘要】 文章首先辨析了数字资源保存的概念,介绍了数字资源保存的发展史和国内外研究现状。然后利用CitespaceⅡ可视化分析工具和方法构建领域知识基础(指引文)的时间序列演化图谱和时区演化图谱,并结合绘制的领域发展趋势图,分析了数字资源保存的研究进展。同时利用CitespaceⅡ可视化分析工具和方法绘制术语与关键词的混合共现网络和引文共被引聚类知识图谱,识别出数字资源保存的研究热点~①,并利用爆发词或突变词探测方法探测数字资源保存的研究前沿。最后针对图书情报与档案管理学科关注最多的研究热点一数字资源长期保存,从研究主题、最佳实践、保存周期、保存技术和方法、保存策略等几个重要方面解读数字资源长期保存的研究进展。更多还原

【Abstract】 Firstly,we discussed the concepts of digital resources preservation,and introduced its developmental history and current status of research at home and abroad.Then a visualizing analysis tool named "CitespaceII" and some visualizing analysis methods were applied to construct time-series evolution mapping and timezone evolution mapping for domain knowledge basis(references),and drew domain’ s development trend chart,with them analyzing research developments of digital resources preservation.Besides,a mixed co-occurrence network between terms and keywords,and some co-cited cluster mappings for quotations were also constructed to identify research hotspots in digital resources preservation,as well as a detection method for burst terms was utilized to detect research fronts in digital resources preservation.Finally,research developments for long-term preservation of digital resources as a research hotspot often focused by scholars in Library,information science and archives administration discipline was reviewed from several important aspects:research topics,best practices,preservation period,preservation technology and methods,as well as preservation strategies.更多还原
