Data Mining in Flight Accident Data

摘要

In this paper, we analyzes the data features in flight accident, constructs the data preprocessing structures, improves the Apriori algorithm and applies it into finding frequent patterns of flight accident data warehouse which is organized as a snow flake schema while improving direct rule graph to visualize the association rules.The result shows that data mining technology for further research on historical flight accident data can not only overcome the limitations of the traditional statistics and analysis but also can mine a lot of knowledge so that some references can be provided for future flight safety.
