Electronic certificate retrieval method and device and computer readable medium

Abstract

The invention provides an electronic certificate retrieval method and device, and a computer readable medium. The method comprises the steps: obtaining basic information and service information of each first electronic certificate; determining identification information of each piece of service information; creating a corresponding ID for each first electronic certificate; generating an electroniccertificate data model; randomly extracting at least one second electronic certificate from each first electronic certificate, and obtaining service information and identification information of eachsecond electronic certificate; determining a first index model; processing the service information and the identification information of each second electronic certificate in the first index model according to a decision tree algorithm to obtain a decision tree; inputting a retrieval scene of the to-be-retrieved electronic certificate data into the decision tree to determine a second index model;and determining a target ID corresponding to the retrieval scene by utilizing a second index model so as to obtain the to-be-retrieved electronic certificate data from the electronic certificate datamodel. According to the scheme, quick retrieval of the electronic certificate can be realized.

Description

technical field [0001] The invention relates to the field of information management, in particular to an electronic certificate retrieval method, device and computer-readable medium. Background technique [0002] With the release of 6 national standards for electronic certificates including "GB / T 36901-2018 Overall Technical Architecture of Electronic Certificates" and "C0126-2018 Data Exchange and Sharing Interface Standards for National Government Service Platforms" and other standards for cross-regional sharing of electronic certificates, for It provides standard support for the realization of cross-level, cross-department, and cross-regional mutual recognition and sharing of electronic certificates and certificates, and the promotion of the integration and sharing of government information resources for certificates and certificates. Therefore, the data volume of electronic certificates continues to increase, and the search requirements of users also increase. It is nece...

Problems solved by technology

[0003] Different types of electronic certificate data are composed of basic information items and business information items. The data characteristics of the basic information items of various types of electronic certificates are similar to the retrieval requirements, while the data value and distribution characteristics of the business information items are not consistent with the retrieval requirements. There are great differences, so it increases the difficulty of promoting the practical application of electronic certificates, and it is difficult to achieve fast retrieval for various combination retrieval requirements of electronic certificates
