摘要
知识图谱由Google公司提出,作为增强其搜索功能的知识库,在近几年得到了迅速发展.随着知识图谱价值不断地被发掘,各类领域知识图谱也迅速建设起来.本文通过领域知识图谱和通用知识图谱的对比来清晰化领域知识图谱的定义,介绍了领域知识图谱的架构,并以医学知识图谱为例讲解了领域知识图谱的构建技术.最后,本文介绍了当前热门的领域知识图谱的发展状况和应用,对当前领域知识图谱状况进行了较为全面的总结.
The knowledge graph has been proposed by Google as a knowledge base to enhance its search function,and has been rapidly developed in recent years.As the value of knowledge graphs is constantly being explored,many domain knowledge graphs are rapidly being built.This study clarifies the definition of domain knowledge graphs by comparing domain knowledge graphs with general knowledge graphs,introduces the architecture of domain knowledge graphs,and uses medical knowledge graphs as an example to explain the construction techniques of knowledge graphs.Finally,this study introduces the development of the current popular domain knowledge graphs,and provides a comprehensive summary of the current domain knowledge graph status.
