基于SCI-E的2010—2014年美国海洋学研究热点分析
ANALYSIS OF RESEARCH HOTSPOTS IN OCEANOGRAPHY OF THE UNITED STATES BASED ON SCIENCE CITATION INDEX EXPANDED FROM 2010 TO 2014
摘要
Abstract
Based on SCI-E, we collated details of almost all documents regarding oceanography published in the United States from 2010 to 2014. By analyzing the co-occurrence frequency of 54 high-frequency keywords using SPSS software and a cluster analysis method, this study revealed the six oceanographic research hots-pots of the United States from 2010 to 2014: ocean circulation dynamics, ocean disasters, application of science and technology methods in oceanography, ocean primary productivity, ocean pollution, and ocean biodiversity. Furthermore, a visualization map was constructed of the co-occurrence matrix of research hot-pots and high-frequency author names, based on social network analysis, to identify the groups of authors associated with these research topics.关键词
