Abstract

En 中文

• We enable the characterisation of a dataset’s usability by introducing the concept of a usability profile. • We propose a framework for modelling corrective actions to address the various data quality problems, enabling users to define the requirements and target usability. • We propose an approach based on the Constraint Optimisation paradigm to select the optimal set of corrective actions to apply to enhance the usability of data. • The DMN4DQ+ methodology includes a data quality life cycle formed of data quality rule descriptions, usability assessments, and corrective action selections for data repair.
