Abstract

The invention discloses an interactive retrieval method and device, computer equipment and a storage medium, belongs to the crossing field of computer software and avionics systems, and is used for improving the retrieval efficiency of an electronic flight bag, guaranteeing the flight operation safety, enabling the flight operation of civil aviation aircrafts to be more modernized, ensuring flightsafety effectively, reducing the workload of pilots, improving economic benefits of airlines, and meanwhile, improving the core competitiveness of civil aviation airplanes. According to the main technical scheme, the method comprises the steps of S1, expanding a query statement input by a user in combination with a knowledge graph; s2, selecting a plurality of documents with higher similarity with the expanded query statement from a document library, and returning the documents to the user; and S3, adjusting the weight of each node in the knowledge graph according to user behaviors, and optimizing a retrieval result.

Description

technical field [0001] The invention relates to the cross field of computer software and avionics system, in particular to an interactive retrieval method, device, computer equipment and storage medium. Background technique [0002] The electronic flight bag is an electronic information management device, which is used to display the navigation data in the electronic display system of the aircraft cockpit, perform performance calculations at each stage of the flight and complete flight operation checks, which can help pilots use less paper, more easily, Effectively perform flight management tasks. The electronic flight bag is an important step in realizing the paperless cockpit of civil aircraft, and it is one of the major innovations in the use and management of airline operation information. [0003] The electronic flight bag includes the on-board computer and the electronic database stored in it. In practical applications, common on-board computers used in electronic fl...
