Rail transit intelligent response method and system based on knowledge graph

Abstract

The embodiment of the invention relates to the technical field of rail transit operation, and provides a rail transit intelligent response method and system based on a knowledge graph, and the methodcomprises the steps: obtaining rail transit electronic data, determining a concept mode of the knowledge graph, and constructing the rail transit knowledge graph according to the concept mode; receiving a first input, and in response to the first input, preprocessing the first input to obtain structured representation information; and converting the structured representation information into a knowledge graph query statement, inputting the knowledge graph query statement into the rail transit knowledge graph for matching retrieval, and outputting response information matched with the first input. According to the embodiment of the invention, the preset rail transit knowledge graph is applied, and the business operation in the rail transit scene can be processed more efficiently, so that the technical problem that the automatic response operation in the rail transit scene is difficult to process efficiently is solved.

Description

technical field [0001] The invention relates to the technical field of rail transit operation, in particular to a rail transit intelligent response method and system based on a knowledge graph. Background technique [0002] With the continuous development of the rail transit system, the data generated by the rail transit system is also increasing, and the data types are becoming more and more complicated. For example, different orbital equipment will generate a large variety of data with complex content in different life cycles. [0003] At the same time, the data format is also diversified, for example, including traditional paper-based data such as manual line inspection logbook, track inspection instrument format data and vehicle on-board controller (VOBC, Vehicle on-board Controller) driving record data, etc. [0004] At the same time, the data structure is also diverse, including structured data, semi-structured data, unstructured data, and so on. [0005] Obviously, ...
