Research on derivative events for Chinese natural disasters based on the Apriori improved model
The article based on the Apriori improved model, combined with the related theory of natural disasters derivative events, analyzes the information data of the natural disaster in the last three years in China, and finally confirms 10 representative derivative events of natural disasters. Through analyzing and sorting, this paper checks the results based on minimum support and minimum confidence, and ultimately determines the relationship between different derivative events. By discussing the items that rank ahead with the high confidence in associated results of the 2-items, 3-items and 4items, respectively, it could be confirmed that the correctness of association results, and reflected the efficiency of the Apriori improved algorithm. Therefore, individuals can use the results to forecast the possibility of related derivative events after natural disasters occurring, with the ultimate goal of improving the prediction system.
