A data matching method and device

Abstract

The invention discloses a data matching method. The data matching method comprises the following steps of: acquiring to-be-processed data to be matched in customer information data; performing format conversion on the to-be-processed data, and generating preprocessed data; partitioning the preprocessed data by using a reverse maximum matching method according to a character string maximum value and a character standard value, which are pre-stored, and generating a plurality of sub-data which are distributed in a descending grade sequence; converting a plurality of sub-data into a standard datum according to sub-data standard names and a character conversion rule, which are pre-stored; and comparing the standard datum with the to-be-processed data, and calculating to generate a matching value. By adoption of the data matching method and a data matching device provided by the embodiment of the invention, comparison efficiency and accuracy are improved, manual operation cost is reduced, a great number of data can be processed, and Chinese data items in customer information data can be systematically, automatically and objectively compared in a process.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data matching method and device. Background technique [0002] At present, when processing various types of customer information data, it is often necessary to perform data comparison, matching and other processing: First, the system obtains more accurate and authoritative personal external data through various channels, such as public security system data, landline telephones, Yellow Pages data, Ministry of Higher Education Educational qualification certification center data (educational qualifications, educational status, etc.) and motor vehicle driver's license data, motor vehicle driving license data, etc. On the other hand, the data entered by the customer needs to be compared with the above data obtained by the system when checking its correctness. However, the data entered by customers is often not standardized, especially information with a large number of char...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the difficulty that the full-character exact matching method in the prior art cannot compare well, match customer information data, and the manual comparison method is inefficient and consumes a lot of manpower and material resources. The data comparison and matching system and method, through the technical processing means of data preprocessing, data segmentation, data conversion and data comparison of customer information data, realize the Chinese fuzzy matching of customer information data, so as to check the accuracy of customer information data Judgment and identification, improve the accuracy and efficiency of comparison and matching, and realize the systematization, automation, process and objectification of matching
