基于知识图谱的航空领域问答系统设计

Design of Question Answering System in Aviation Field Based on Knowledge Graph

知识图谱作为一种人类可识别且对机器友好的知识表示,近年来得到了越来越广泛的应用。但在航天领域,相关知识图谱构建和应用较少。笔者总结了知识图谱构建的理论知识,提出了航空知识图谱的具体构建过程,并设计出问答算法。航空知识图谱的主要构建流程包括知识图谱数据的采集、知识抽取以及基于Neo4j的知识存储,其中问答系统针对问题分析、模板匹配进行设计。在总结知识图谱构建理论的基础上,为航空领域知识图谱的构建工作提供可行方案。

As a human-recognizable and machine-friendly knowledge representation,knowledge graphs have been widely used in recent years.However,in the aerospace field,the construction and application of related knowledge graphs is less.The author summarizes the theoretical knowledge of knowledge graph construction,proposes the specific construction process of aviation knowledge graph,and designs a question answering algorithm.The main construction process of aviation knowledge graph includes knowledge graph data collection,knowledge extraction and knowledge storage based on Neo4 j.The question answering system is designed for problem analysis and template matching.On the basis of summarizing the theory of knowledge graph construction,a feasible scheme is provided for the construction of knowledge graph in the aviation field.
