CleanEr

This repository contains a prototype implementation for CleanEr, a generic framework that is used on top of existing data cleaning systems and that assists users in identifying the impact of potential cleaning errors on query results, and in deciding accordingly whether and how to proceed with the cleaning.

You can find screenshots of the different views under screenshots/, and watch a video that demonstrates our framework and its key features.
