Embodiment Construction

[0020] The terms "system" and "network" are often used interchangeably herein. The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

[0021] The implementation of the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

Abstract

The embodiment of the invention discloses a data matching method and device and relates to the field of communication. The mismatching problem caused when data of different data sources is subjected to fuzzy matching is solved. According to the specific scheme, first data records and second data records are obtained, an association field and a to-be-matched field of the data records are obtained,the data records with the key values same as that of the association field in the first data records belong to the same group to obtain a first group set, the data records with the key values same asthat of the association field in the second data records belong to the same group to obtain a second group set, the two data records of the first group and the second group are associated, a to-be-matched distance of the two associated data records is calculated, the data record with the smallest absolute value in the to-be-matched distance is determined as the record which is successfully matched, and the associated data record with the field value same as that of the to-be-matched field in the successfully matched associated data record is deleted. The method and device are used in the datamatching process.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a data matching method and device. Background technique [0002] With the rise of the big data industry, all walks of life have paid more attention to the value of data. In the data life cycle, there are two main links: data generation and data application. Among them, in the data application link, it is necessary to perform fuzzy matching on the data generated by multiple data sources. Specifically, the fuzzy matching of data can be performed by distance. [0003] For example, in the case of fuzzy matching of the call records of the two data sources of the network side and the billing center, the calling number can be used as the associated field to obtain the call records with the same calling number from the two data sources, and Take the call start time as the field to be matched, and match two call records from two data sources with the same calli...
