摘　　要：知识图谱作为一种新型的知识应用工具,给结构化、半结构化以及非结构化数据的处理、分析和应用提供了新的解决方法,而本体构建是构建知识图谱的基础。从自动化程度、可扩展性、复杂程度等多个角度对骨架法和七步法等传统的本体构建方法和本体构建工具进行了对比分析,从应用的角度介绍了部分领域本体构建现状,并分析了本体构建流程和构建技巧。最后分析并确定了天然气市场供应端、需求端和外部环境的本体构架。按照构建天然气市场主题词表、主题词向本体映射、关系映射、七步法构建外部环境本体的步骤一步步对天然气市场本体进行完善,最终实现天然气市场本体构建。As a new knowledge application tool,knowledge graph provides a new solution to the processing,analysis and application of structured,semi-structured and unstructured data.Ontology construction is the foundation of knowledge map construction.Traditional ontology construction methods and tools such as skeleton method and seven-step method are analyzed and compared from the degree of automation,extensibility and complexity.Besides,this article introduces the reality of ontology construction in some fields from the perspective of application,and analyzes the process and techniques of ontology construction.Finally,this article analyzes and identifies the ontology framework concerning the supply-side,demand-side as well as the external environment of the natural gas market.In line with the steps of construction of the descriptor list of natural gas market,mapping to ontology,relational mapping and seven-step method,the ontology of natural gas market can be improved step by step,so as to achieve the construction of the natural gas market.
