Abstract:
Web portals facilitate access to data on the Internet. Their use and quantity have increased, which has led to the need to satisfy user preferences in order for them to continue on the market. One competition-based strategy is to provide an adequate quality of service, and one of the key factors in this is the quality of the data provided by the Web portal. Bearing this in mind, we have defined a Data Quality (DQ) Model for Web portals. This model is composed of 42 DQ characteristics which are organized into two points of view and four DQ categories. In this paper we present work which is based on the statistical study of users’ opinions of one of the characteristics in the model – the Intrinsic DQ category. Our objective is to determine which characteristics in the Intrinsic category will be most relevant as regards the users’ gender, age range, level of studies and knowledge of computing, thus allowing us to verify that, according to the aforementioned parameters, the importance of
some characteristics varies with regard to others. For example, women place more importance upon Credibility, while men view the Accessibility of the data in Web Portals as being more important.
