Reasoning about Data Licensing in the Web of Data

Participants : Fabien Gandon, Serena Villata.

In the domain of Linked Open Data a need is emerging for developing automated frameworks able to generate the licensing terms associated to data coming from heterogeneous distributed sources. Together with Guido Governatori (NICTA, Australia) and Antonino Rotolo (University of Bologna, Italy), we proposed and evaluated a deontic logic semantics which allows to define the deontic components of the licenses, i.e., permissions, obligations, and prohibitions, and generate a composite license compliant with the licensing items of the composed different licenses. The AND-composition and OR-composition heuristics have been proposed to support the data publisher in choosing the licenses composition strategy which better suits her needs w.r.t. the data she is publishing. The approach has been evaluated using the SPINdle defeasible reasoner, where the proposed heuristics have been hard coded in the reasoner. The results of this research line have been published in [50] , [38] .
