Abstract

The present invention discloses a data cleaning method. The method comprises: acquiring to-be-cleaned data, and according to analysis for noise data distribution in the to-be-cleaned data, obtaining to-be-cleaned fields in the to-be-cleaned data; searching a field which can be subjected to dimension expansion in the to-be-cleaned data, and performing high-order tensor dimension-expanding on the field which can be subjected to dimension expansion to obtain M tensor fieldsets; and carrying out data cleaning on the to-be-cleaned fields by using tensor fields in the tensor fieldsets, which are associated with the to-be-cleaned fields. The present invention also discloses a data cleaning apparatus.

Description

technical field [0001] The invention relates to data processing technology in the computer field, in particular to a data cleaning method and device. Background technique [0002] With the advancement of science and technology and the rapid development of computer technology, people can obtain more and more digital information, and at the same time need to invest more time in organizing and sorting out the information. Before performing statistical analysis on the data, it is necessary to filter out the dirty data in the data, that is, noise data, to ensure the accuracy of the statistics. Data cleaning is a process of detecting and eliminating data errors and inconsistencies in the database and improving data quality. Its principle is to use related technologies to convert data into data that meets data quality requirements. [0003] However, there are at least the following problems in the existing related technologies of data cleaning: 1) the related technologies mainly d...
