Abstract

The invention provides a flight delay prediction method based on a knowledge graph, and the method comprises the steps: obtaining delay prediction data based on the knowledge graph; adding flight plan data into the knowledge graph, namely, creating a plurality of entities and relationships among the entities; analyzing flow control message data from an unstructured text into a structured text; adding the analyzed structured flow control message into the knowledge graph; generating a training set according to the attribute of a flight entity in the knowledge graph, the relation between the flight entity and a way point entity and the relation between the way point entity and the flow control message; and finally, according to the training set, using a machine learning algorithm for training a prediction model, and outputting a flight delay prediction result. Compared with the prior art, the method has the advantages that the data source is complete, the delay condition of the global flight can be effectively predicted, and the accuracy of the prediction result of the flight delay is improved.

Description

technical field [0001] The present invention relates to the technical field of machine learning, in particular to a method for predicting flight delays based on knowledge graphs. Background technique [0002] With the current development of civil aviation, flying has become a common way of travel for people. However, there are currently increasing delays to flights due to reduced capacity due to weather, military activity, etc. [0003] When delays are unavoidable, predicting delays in advance will help airlines and passengers take countermeasures in advance and reduce the impact of flight delays. [0004] There are many factors that affect whether a flight is delayed, including flight departure time, flight duration, flow control, etc. Since these data come from different data sources, such as flight plan data for departure time, and flow control messages for flow control, there is a lack of correlation between various types of data, making it difficult to fully integrate...
