民国南海文献知识元内容抽取规则研究

Research on the Extraction Rules of Knowledge Element Contents in the South China Sea Documents of the Republic of China Period

[研究目的]南海问题的深入研究,需要从海量历史文献中快速获得知识描述,实现由文献向语句描述的内容抽取,因此引入最小知识描述单位--知识元,并研究其抽取规则,为南海维权信息内容抽取提供新思路,以方便研究者快速浏览文献知识。[研究方法]基于民国南海文献总结知识元分类,归纳不同属性类型知识元句法规则,提炼形成规则模板,匹配文本与知识元描述规则,人工干预确定知识元内容,实现知识元的内容抽取。[研究结论]匹配结果发现,内容描述规则能较好地实现知识元抽取,满足研究者对知识元内容的阅览需求。

[Research Purpose]The in-depth study of the South China Sea issue requires rapid acquisition of knowledge descriptions from massive historical documents and the realization of content extraction from documents to sentence descriptions.Therefore,the smallest unit of knowledge description-knowledge element is introduced,and its extraction rules are studied to extract the content of rights protection information in the South China Sea,thus to provide new ideas to facilitate researchers to quickly browse literature knowledge.[Research method]Based on the South China Sea literature of the Republic of China Period,the knowledge meta classification is summarized,the knowledge meta syntax rules of different attribute types are summarized,the rule templates are refined,the text and the knowledge meta description rules are matched,the knowledge meta content is determined by manual intervention,and the content extraction of the knowledge meta is realized.[Research conclusion]The matching results show that the content description rules can better achieve knowledge element extraction and meet the researchers'reading needs for knowledge element content.
