：智慧信息服务是信息服务与大数据时代紧密结合的表现形式。有效分析信息服务中海量、多样、高速处理、价值大密度低的大数据是促进智慧信息服务研究发展的关键。文章通过对2013-2018近五年收录在Web of Science数据库中图书情报领域发表的有关智慧信息服务的文献进行分析，采用文献研究法和频次分析法对智慧信息服务大数据分析方法与研究主题进行研究，从而构建出了一个主要包括大数据分析层和大数据应用层的大数据分层分析框架。

Intelligent information service is a form of interaction between information service and  big data. An Effective analysis of volume, variety, velocity and valuable but low density big data is the key to promote the researches and development of intelligent information service. Based on nearly five years (2013-2018) relevant articles which were published in Web of Science by librarians, the big data analysis methods and the research topics of intelligent information service were analyzed. Through literature study and frequency analysis,  a layered analysis  framework was constructed, which includes big data analysis layer and application layer.
