Propagating Data Policies: a User Study

Daga, Enrico; d'Aquin, Mathieu and Motta, Enrico (2017). Propagating Data Policies: a User Study. In: Proceedings of the Knowledge Capture Conference, ACM, New York, NY, USA, article no. 3.



When publishing data, data licences are used to specify the actions that are permitted or prohibited, and the duties that target data consumers must comply with. However, in complex environments such as a smart city data portal, multiple data sources are constantly being combined, processed and redistributed. In such a scenario, deciding which policies apply to the output of a process based on the licences attached to its input data is a difficult, knowledge- intensive task. In this paper, we evaluate how automatic reasoning upon semantic representations of policies and of data flows could support decision making on policy propagation. We report on the results of a user study designed to assess both the accuracy and the utility of such a policy-propagation tool, in comparison to a manual approach.
