A formulation of the data quality optimization problem in Cooperative Information Systems

ABSTRACT
The execution of inter-organization business processes involves the exchange of large amounts of structured data across distributed and cooperative information systems. Since the quality of those processes is directly affected by the quality of the data they acquire from other processes, we introduce a model whereby processes may (i) state their requirements on the types and quality of incoming data (data and data quality demand), and (ii) advertise the type, quality and the cost of the data they can supply to other processes (data and data quality offer). Using this model, we formulate the problem of optimizing the cost of data exchange under quality requirements constraints. This is formalized as an Integer Linear Programming problem that outputs an optimal matching of data providers to data consumers. We also show how a quality monitoring service may provide the necessary input to the problem in a realistic setting.
