基于知识图谱的国内外大数据研究对比分析

Comparative Analyses on Domestic and Overseas Big Data Based on Mapping Knowledge

本文以CNKI和WOS为数据源,从文献计量角度,对2008-2013年国内外大数据领域的文献进行统计分析。利用可视化分析工具生成国内外大数据研究成果的年限分布表、关键词共现矩阵、关键词共现图谱和关键词共现聚类图谱,对比分析了国内外大数据领域研究的异同。

Using CNKI and WOS as the searching tools, this paper makes an analysis from bibliometrics perspective on papers of big data at home and abroad, published during the period 2008-2013. With visualization tools forming a distribution table of keywords co-occurrence matrix, keywords co-occurrence network and keywords co-occurrence clustering map, the paper compares and analyses similarity and difference on big data from international aspect.
