摘要
【目的】从大数据研究的整体视角分析图情领域大数据的研究主题,并进一步讨论研究发展趋势。【方法】以"大数据"为主题检索Web of Science获得原始文献集,根据引用关系剔除和扩充文献,利用Leiden算法和VOSViewer软件构建了大数据研究知识图谱,最后通过图情领域论文分布Overlay图谱和引文Overlay图谱分析该领域的大数据研究主题。【结果】从论文分布Overlay图谱来看,图情领域大数据研究主要集中在大数据分析和社交媒体分析,其次是云计算、Hadoop、MapReduce、机器学习等;从引文Overlay图谱来看,除大数据分析和社交媒体分析外,云计算、机器学习、健康信息、精准医疗、工业4.0和物联网也是图情领域关注较多的主题。【局限】大数据研究涉及的论文较多,只能从宏观上分析大数据环境下图情领域的主题和发展趋势。【结论】大数据研究是图情领域的重要研究主题和发展趋势,目前的研究主要集中在大数据分析和社会媒体分析,而机器学习、健康信息、精准医疗、工业4.0和物联网可能是未来关注和发展的方向。
[Objective]This paper explores the topics of big data research in Library and Information Science(LIS),aiming to reveal their developing trends.[Methods]We used"big data"as keyword to search the Web of Science and then constructed a test collection with the retrieved documents.Based on the citation analysis,we removed those irrelevant documents.Then,we used the Leiden algorithm and the VOSviewer to construct the science mapping on LIS big data research.Finally,we created the overlay mapping of research topics.[Results]According to the citation analysis,LIS big data research focuses on big data and social media analysis,followed by cloud computing,machine learning,big data technologies(such as Hadoop and MapReduce),health information,precision medicine,industry 4.0 and Internet of Things.[Limitations]We only analyzed the themes and development trends of LIS big data research from the macro-perspective.[Conclusions]Big data is an important LIS research topic.Popular studies focuses on big data and social media analysis.Machine learning,health information,precision medicine,Industry 4.0 and the Internet of Things are the important directions for Library and Information Science.
