DATA QUALITY EVALUATION

Abstract:

Methods and systems for data quality evaluation are disclosed. A method includes: receiving, by a computing device, at least one data set and a list of rule expressions to bind; building, by the computing device, candidate binding combinations between columns of the at least one data set and variables of each rule expression in the list of rule expressions; building, by the computing device, a new bound rule expression candidate based on the candidate binding combinations; generating, by the computing device, a new bound rule expression based on the new bound rule expression candidate and a data transformation applied to at least one of the columns of the at least one data set; and storing, by the computing device, the new bound rule expression.
