ID card address information analysis method and system based on character string matching

Abstract

The invention discloses a method and system for parsing address information of an ID card based on character string matching. Firstly, the country's provinces, cities, counties and districts and their corresponding codes are obtained, and all normalized address code entries are read into a storage medium, and each address is The code entry is stored in two mapping ways at the same time, one is the dictionary mapping between the lowest-level field and the code in the address code entry, and the other is the mapping from the code to the full name of the province, city and county; read the characters of an ID card address information Only the corresponding keywords of the district, county and city are retained to obtain the key information strings, and the key information strings are matched and intercepted from low-level to high-level in sequence, and the corresponding codes and the corresponding full names of provinces, cities and counties are obtained according to the two mappings. The invention can automatically obtain detailed province, city and county information very effectively and reliably, saves a lot of manpower, solves the problem of irregular address information on ID cards, prevents errors in digitized personal information, and ensures the accuracy of subsequent applications.

Description

technical field [0001] The present invention relates to the application field of computer engineering technology, more specifically, it is a technical scheme for parsing ID card address information based on character string matching. Background technique [0002] The 21st century is an era of informationization. In order to make people's lives more and more intelligent and interconnected, the digitalization and networking of personal information is a necessary step. As the most important identity symbol of residents, the resident ID card is of great significance to the identification of personnel activities, and the analysis of user information based on this is of great significance to user experience and resident safety. Obtaining resident address information through ID cards is an important application of digital personal information. [0003] The ID card address information analysis system first reads the user ID card information, and then obtains the user's province, ci...
