(57) Abstract: A method for data cleaning i s disclosed. The method includes: obtaining sample data classified roughly and taking
the obtained sample data as a first data set(101); classifying the sample data, obtaining a weight of rough classification category of
the sample data, and determining a ranking position of the rough classification category of the sample data in all categories ac
cording to the weight; obtaining a comprehensive evaluation result according to the ranking position of the rough classification
category of the sample data in all categories and the total amount of the sample data in the first data set(103); when i t is deter
mined on the basis of the comprehensive evaluation result that the first data set needs cleaning, deleting the prescribed amount of
the sample data positioned at the last according to the ranking position of the rough classification category of the sample data in
