面向科技文献的国内外知识挖掘研究热点与展望——基于WOS核心合集与CNKI数据库的计量分析

Research Hot spots and Prospects of Knowledge Mining for Scientific and Technological Literature at Home and Abroad-Quantitative Analysis Based on WOS Core Collection and CNKI Database

以WOS核心合集与CNKI数据库作为数据来源,运用文献计量和内容分析方法,借助Citespace、VOSviewer对国内外关于科技文献的知识挖掘研究情况进行系统梳理。通过对发文趋势、作者共现、机构共现和关键词共现进行分析,揭示该领域的热点主题与发展趋势。研究发现关于科技文献知识挖掘的热点主题集中于面向科技创新的知识挖掘、知识产权与主题演化分析、细粒度知识抽取及知识关联挖掘等方面。提出未来需要探索多样化的知识挖掘方法,以更好地开发科技文献价值的相关建议。

Taking the WOS core collection and CNKI database as data sources,using bibliometric and content analysis methods,with the help of Citespace and VOSviewer,knowledge mining research on scientific and technological literature at home and abroad is systematically sorted out.By analyzing the publication trend and the co-occurrence of authors,institutions and keywords,this paper reveals the hot topics and development trends in this field.It is found that the hot topics about knowledge mining of scientific and technological literature are concentrated in the aspects of knowledge mining for scientific and technological innovation,intellectual property and topic evolution analysis,fine-grained knowledge extraction and knowledge association mining.Some suggestions are put forward that diversified knowledge mining methods should be explored in the future to better exploit the value of scientific and technological literature.
