Abstract

The invention discloses a data processing method. A technical scheme of the invention shows that data sets are sorted and grouped by utilizing zone bit codes of key field characters according to the method, so that the operation efficiency and detection precision of the method are improved; and through selecting the representative characters in the groups and deleting the unrelated characters, the character matching frequency during similar repeated record detection is decreased, so that the operation time of record matching is shortened, the similar repeated record detection problems of large data volumes can be effectively solved, and an effect of cleaning useless data of data sources is provided.

Description

technical field [0001] The present invention relates to the field of data processing, and more specifically, to a data cleaning and processing method. Background technique [0002] With the growing maturity of the research in the field of data mining, people's requirements for data quality are getting higher and higher. However, because there are a lot of redundant or missing data in the data warehouse, as well as inconsistent or uncertain data, the quality of the data is reduced. We call these data that affect the quality of the data "dirty data". According to the principle of "garbage in, garbage out", dirty data will affect the quality of data mining, make the decision-making analysis system get wrong analysis results, and ultimately mislead the decision-making, affecting the accuracy of the decision-maker's prediction and decision-making. In addition, dirty data can lead to expensive operations and long response times. Therefore, we must clean the dirty data. A large ...
