基于双向迭代的航空发动机试验知识图谱构建方法研究

Construction method of aero-engine test knowledge graph based on bi-directional iteration

针对航空发动机试验领域的知识特征所具有的应用难点,设计了面向航空发动机试验领域的知识图谱框架结构;并在对知识自动化获取关键技术研究的基础上,提出了基于双向迭代的领域图谱构建方法。以涡扇发动机整机试验相关知识及其文档作为方法验证对象,通过实现不同类别知识图谱数据模式设计和专题图谱漫游检索,验证了所提出方法的可行性和有效性。

Aiming at the application difficulties of knowledge in the field of aero-engine test,a framework for aero-engine test knowledge graph was designed.Based on the research of knowledge automation acquisition,the construction method based on bi-directional iteration was proposed.With the knowledge and documents of aero-engine test as the object of the research,the feasibility and effectiveness of the proposed method were verified by designing knowledge and data patterns of different categories and searching thematic graphs.
