大数据领域理论研究的发文分析与热点分析

Analysis of Articles and Hot Topics of Theoretical Research in the Big Data Field

目的对大数据领域的研究论文进行分析,了解我国在大数据研究领域的科研实力和高产机构,以及大数据领域目前的前沿热点问题。方法综合使用Web of Science自带的分析功能,以及2种可视化的文献科学计量方法:可视化分析软件UCINET和g CLUTO软件,检索美国《科学引文索引》(Web of Science)数据库,进行发文分析、词频分析、共现分析与双聚类分析。结果美国、中国和英国的研究水平位列前3位。中国科学院和清华大学,在机构排名中分别排名第1和第3位。中国科学院遥感与数字地球研究所的王力哲研究员,以第一作者发表的论文最多。大数据研究的主要热点除了大数据的研究综述以外,还集中在:分析方法研究、应用现状研究、趋势研究、在决策中的应用、处理模型和趋势研究等7大方面。结论关于大数据的研究在世界范围内开展的如火如荼,是当今科学界的热点问题。

Objective To analyze the research papers in the field of big data so as to understand the scientific research strength and high-yield institutions in the field,and the current frontier hot topics in the field of big data. Methods Using the analysis capabilities of Web of Science and two visual scientific methods,i.e. visual analysis software UCINET and g CLUTO software,retrieval from ＂ Science of Citation Index ＂（ Web of Science） database was performed,and the message analysis,word frequency analysis,co-occurrence analysis and double cluster analysis were conducted. Results The United States,China and the UK were the top three in the world in research capabilities. Chinese Academy of Sciences and Tsinghua University were ranked the first and third respectively. Wang Lizhe,a researcher from the Institute of Remote Sensing and Digital Earth of Chinese Academy of Sciences has published the most articles as the first author. The main hots topics of big data research included analysis method research,application status research,trend research,application in decision making,processing model and trend research in addition to review of big data studies. Conclusion Research on big data is flourishing worldwide as a hot issue in today＇s scientific circle.
