Data Quality and Explainable AI

open access: yesJournal of Data and Information Quality, 2020
In this work, we provide some insights and develop some ideas, with few technical details, about the role of explanations in Data Quality in the context of data-based machine learning models (ML). In this direction, there are, as expected, roles for causality, and explainable artificial intelligence .
