Organizations are nowadays immersed in the Big Data Era. Beyond the hype of the concept of Big Data, it is true that something in the way of doing business is really changing.

A challenge that becomes even trickier is the one concerning to the management of the quality of big data. More than ever the need for assessing the quality-in-use of big datasets gains importance since the real contribution – business value- of a dataset to a business can be only estimated in its context of use. Although there exists different data quality models to assess the quality of data there still lacks of a quality-in-use model adapted to big data. To fill this gap, and based on ISO 25012 and ISO 25024, we propose the 3Cs model, which is composed of three data quality dimensions for assessing the quality-in-use of big datasets: Contextual Consistency, Operational Consistency and Temporal Consistency.Read the full paper here: https://link.springer.com/chapter/10.1007/978-3-319-12256-4_7
