Abstract

The invention discloses an aircraft knowledge graph construction method, device and equipment and a storage medium, and the method comprises the steps: obtaining the structural data, semi-structural data and non-structural data of an aircraft, and determining a mode layer of an aircraft knowledge graph; structured data, semi-structured data and non-structured data of an aircraft are extracted by means of field extraction, rule template extraction and feedback long-short term memory neural network and conditional random field model extraction, so that knowledge triples of different data types are obtained, and then the aircraft knowledge graph is constructed. According to the method, an improved feedback long-short-term memory neural network and conditional random field model extraction mode is adopted in the process of extracting the unstructured data of the aircraft, so that the problem that a traditional long-short-term memory neural network is poor in recognition effect when the context relevance is low is solved; the relation between different entities of the aircraft knowledge graph is enhanced, and the construction efficiency and the structural rationality of the aircraft knowledge graph are improved.

Description

technical field [0001] The present invention relates to the technical field of knowledge graphs, in particular to a method, device, equipment and storage medium for constructing aircraft knowledge graphs. Background technique [0002] Among the many ways of knowledge management integration and representation, the emerging knowledge structured representation method - knowledge graph, is playing an increasingly important role in the analysis and processing of large-scale data and information mining. Knowledge graph is a structured semantic knowledge base, which is used to describe concepts and their interrelationships in the physical world in symbolic form. It is the basic technology for intelligent services such as semantic search, intelligent question answering, and personalized recommendation, and can effectively integrate isolated information. , understand natural semantics and mine new knowledge. [0003] In the aircraft knowledge graph, different fields with a large gap...
