María Angélica Caro Gutiérrez, Coral Calero Muñoz, Emilia Mendes, Mario Piattini Velthuis
Advances in technology and the use of the Internet have favoured the emergence of a large number of Web applications, including Web Portals. Web portals provide the means to obtain a large amount of information therefore it is crucial that the information provided is of high quality. In recent years, several research projects have investigated Web Data Quality; however none has focused on data quality within the context of Web Portals. Therefore, the contribution of this research is to provide a framework centred on the point of view of data consumers, and that uses a probabilistic approach for Web portal's data quality evaluation. This paper shows the definition of operational model, based in our previous work.
