基于SCIE核心期刊的国际生物信息学领域发展脉络研究及热点探析

Research on the Global Development of Bioinformatics Based on the Core Journals of SCIE

梳理国际上生物信息学领域发展至今的脉络态势及热点研究,为行业领域内科研人员提供文献信息支撑依据,也为我国未来生物信息学科的发展提供建议和指导。以SCIE11种国际生物信息学期刊1998-2019年发表的文献为信息源,结合文献计量学方法对发文国家、机构等情况进行阐述。利用Histcite、Pajek对1998-2014年文献进行脉络梳理及可视化分析并筛选出主要路径。运用BICOMB、gCluto对2015-2019年文献进行关键词聚类分析来探析研究热点。根据引文编年图和主要路径中的文献信息总结出1998-2014年生物信息学领域9个方面的研究热点并筛选出3条主要路径;获得2015-2019年生物信息学领域的6类研究热点。

This paper analyzes the development trend and hot spots of bioinformatics in the world,provides literature support for researchers in the field,and offers suggestions and guidance for the development of bioinformatics in China in the future.Based on the 11 international bioinformatics journals published from 1998 to 2019 by SCIE,the authors adopt the bibliometrics method to describe the issuing countries and institutions.Histcite and Pajek are used to analyze the literature from 1998 to 2014,whereas the main path is elaborated through visual analysis.BICOMB and gcluto are then used to conduct keyword clustering analysis on literature from 2015 to 2019 to explore research hotspots.According to the literature information in the citation chronology chart and the main path chart,the research hotspots in 9 aspects of bioinformatics from 1998 to 2014 are summarized and 3 main paths are selected.6 research hotspots in the field of bioinformatics from 2015 to 2019 are obtained.
