【目的/意义】梳理情报学的研究内容分布以及研究主题发展情况。【方法/过程】选取2006年到2015年十年内发表于九种情报学核心刊物的论文作为研究数据源,采用构建基于LDA算法的主题模型的方法挖掘情报学的研究主题。【结果/结论】2006年到2015年情报学的研究主题有13个,其中在内容分布上,总体研究热度较高的是图书馆管理、文献计量、知识管理与服务、信息素养和情报学基础理论。在主题变化上,研究热度上升的主题有文献计量、社会网络分析、信息行为研究和数据挖掘;研究热度下降的主题有信息素养、情报学基础理论、信息检索和企业竞争情报。
Purpose / Significance Combing the distribution of information science research and the development of research topics. Methods / Processes The papers published in the nine core journals of informatics from 2006 to 2015 were selected as research data sources, and the theme of information science was explored by constructing a thematic model based on LDA algorithm. [Results / Conclusions] There are 13 research topics in information science from 2006 to 2015. Among them, the content distribution mainly focuses on library management, bibliometrics, knowledge management and service, information literacy and information science theory. In terms of thematic changes, the topics of research fever rise are bibliometrics, social network analysis, information behavior research and data mining. The topics of research fever drop are information literacy, basic theory of information science, information retrieval and enterprise competitive intelligence.
