摘　　要：以国内2002年1月至2016年5月间发表的与基于本体的信息抽取有关的期刊文献为分析对象,运用内容分析法从领域本体的构建及基于本体的信息抽取方法、信息抽取模型、信息抽取算法、信息抽取系统、信息抽取的应用领域等6个方面对国内该领域的研究现状与热点进行分析,认为目前国内该研究领域具有研究内容从理论走向实践、研究主体多样性、尚未形成核心作者和核心团队等特点,指出本体构建的自动化及基于本体的信息抽取的评估机制、信息抽取的实践应用将成为未来的发展趋势。Taking periodical literature issued from January 2002 to May 2016 that related to the information extraction based on ontology as research objects, this article makes an analysis on research status and hotspot of ontology with the method of content analysis from 6 aspects： construction of ontology, information extraction model, information extraction algorithm, information extraction system, and information extraction application. This article finds that current domestic research content is featured from theory to practice, diversity and absent of core authors and core group. It points out that the automation of ontology construction, the evaluation mechanism of ontology based on information extraction and the practical application of ontology based on information extraction will become the future development trend.
