摘要
该文从主题模型的基本原理、起源和历史演变出发,梳理和揭示主题模型的国内外研究进展情况,以期为相关研究人员提供借鉴和参考。以Web of Science核心合集和中国学术期刊网络版(CNKI学术期刊全文数据库)为数据源,分别检索主题为"主题模型"的学术文献,采用文献外部特征统计分析和共词分析方法,从时间趋势、机构分布、核心作者、学科、期刊分布等角度揭示主题模型的国内外研究发展态势,并归纳总结主题模型的研究热点分布。研究显示,主题模型研究整体上呈现增长态势,且增速相对较快,其中,中国作为主题模型研究的后起之秀,在该领域已成为国际上主要的研究群体,对推动主题模型的发展起到了积极作用。另外,基于上述两个不同的数据库,揭示了国内外在主题模型领域的研究内容和热点主题既存在一致性也存在差异性,差异性主要体现在研究层次、研究方法和研究对象方面。
This paper studies the principle, origin and evolution of topic model, analyzes the research progress of topic model both China and world, so as to provide reference and idea for related researchers. Based on Web of Science Core Collection and CNKI （China Academic Journals Full-text Database）, this paper retrieves and screens related articles which the subject is ＂topic model＂, adopts bibliometrics method to analyze the distribution of public year, institutions, authors, disciplines and journals, summarizes the research hotspots of topic model. This paper reveals that the topic model research is in the high-speed growth both China and world, as the rising star of topic model research, China has become the major research group in this field, and plays an important role in promoting the development of topic model. In addition, there are similarities and hotspots between China and world, the differences reflect in objects. as well as differences in the research contents research level, research methods and research
