Problems solved by technology

Since the civil aviation safety field has not yet formed a systematic and classified knowledge system, the accumulated information is basically stored independently in each system, and there is no effective correlation between various events.
[0003] In addition, most of the risk management and analysis in the field of civil aviation safety center on the safety incident records, and its statistical analysis and application are limited to the simple analysis of the appearance characteristics of the incident. The depth of risk analysis is not enough, and the accuracy is not high.

Abstract

The invention relates to a civil aviation safety risk analysis method and device based on a knowledge graph, and the method comprises the steps: determining a target risk with a risk value greater than or equal to a first risk threshold from the knowledge graph of a preset civil aviation safety field, wherein the knowledge graph comprises a plurality of objects of the civil aviation safety field,wherein the category of an object comprises a risk, and the attribute of the risk comprises a risk value; determining a target object associated with the target risk from the knowledge graph, whereinthe category of the target object comprises at least one of an airport, an airline company and a model, and the attribute of the target object comprises a risk value; and under the condition that therisk value of the target object is greater than or equal to a second risk threshold, generating risk early warning information for the target object. According to the embodiment of the invention, themining depth and accuracy of civil aviation safety risk analysis can be improved.

Description

technical field [0001] The present disclosure relates to the field of civil aviation safety, in particular to a method and device for analyzing civil aviation safety risks based on knowledge graphs. Background technique [0002] At present, my country has accumulated a large amount of information in the field of civil aviation safety, such as safety incidents, overrun incidents, and accident investigation reports. Since the civil aviation safety field has not yet formed a systematic and classified knowledge system, the accumulated information is basically stored independently in each system, and there is no effective correlation between various events. [0003] In addition, most of the risk management and analysis in the field of civil aviation safety center on the safety incident records, and its statistical analysis and application are limited to the simple analysis of the appearance characteristics of the incident. The depth of risk analysis is not enough, and the accurac...
