Research on the Collection Method of Financial Blockchain Risk Prompt Information from Sandbox Perspective

Abstract

In view of the low accuracy of the current collection method of financial blockchain risk prompt information, the collection method of financial blockchain risk prompt information under the sandbox view threshold is proposed. Under the sandbox vision, the parser parses the URL of financial blockchain risk prompt message and USES the buron filtering algorithm to de-weight the URL. The URL after weight removal is added into the library to be crawled, and the crawling URL is clustered by using the clustering algorithm to calculate the similarity between URL and noise URL in the cluster, and the URL with high similarity is removed. The web crawler collects the URL queue after denoising, saves the collected URL to the database, and runs the URL resolution program to complete the collection of risk warning information. Through the comparison test with the current information collection method, it proves that the designed method of financial block chain risk prompt information collection under the sandbox vision threshold has higher collection accuracy and advantages.
