基于科研本体的国防科技知识图谱构建

Scientific research ontology-based national defense science and technology knowledge graph-making

以海量科技文献为对象构建国防科技知识图谱。研究了知识图谱的定义和构建的相关技术,结合科技文献特点,提出了从科研本体模式构建知识图谱的思路。将国防科技分类一体化词表与科研本体相结合,通过国防科技海量文献元数据进行实体概念抽取、归一和关联建立,构建了国防科技知识图谱,并开展服务应用,提高了国防科技文献利用的有效性。

The present knowledge graph-making project is focused on the Internet information resources while studies on knowledge graph-making based on massive scientific literature are few. The definition of knowledge graph and its relevant making techniques were thus studied with certain ideas proposed for knowledge graph-making based on scientific research ontology model. The national defense science and technology knowledge graph was made by combining the unified national defense science and technology classification vocabulary with scientific research ontology, normalizing the entity concepts extracted from the massive scientific literature on national defense, and establishing their association. Its application in literature service has effectively improved the use of literature.
