Linking Trust to Data Quality

Trust in data is a user-oriented and subjective phenomenon that hooks on specific data qualities. This paper lays the foundations for studying the existence of a correlation between data qualities and trust. In particular, if these data qualities can be measured by relying on the data only, then it would be possible to infer the likelihood of a given piece of data to be trusted based on a specific measurement made on the data itself. Here we provide a categorization of data quality dimensions as intrinsic (i.e., measurable by analyzing the data only) and extrinsic, and we model it using the W3C Data Quality Vocabulary. We show how it is possible to align credibility, an extrinsic data quality, with trust. This alignment will serve as a basis for a future investigation about the existence of a correlation between trust and intrinsic data qualities.
