Interaction between Record Matching and Data Repairing

Central to a data cleaning system are record matching and data repairing. Matching aims to identify tuples that refer to the same real-world object and repairing is to make a database consistent by fixing errors in the data by using constraints. These are treated as separate processes in current data cleaning systems, based on heuristic solutions. This paper studies a new problem, namely, the interaction between record matching and data repairing. The authors show that repairing can effectively help users identify matches, and vice versa.
