Establishing Trust Networks Based on Data Quality Criteria for Selecting Data Suppliers

Abstract

Nowadays, organizations may have Web portals tailoring several websites where a wide variety of information is integrated. These portals are typically composed of a set of Web applications and services that interchange data among them. In this setting, there is no way to find out how the quality of the interchanged data is going to evolve successively. A framework is proposed for establishing trust networks based on the Data Quality (DQ) levels of the interchanged data. We shall consider two kinds of DQ: inherent DQ and pragmatic DQ. Making a decision about the selection of the most suitable data supplier will be based on the estimation of the best expected pragmatic DQ levels. In addition, an example is presented to ilustrate framework operation.
