Facilitating Reuse on the Web of Data

Abstract : The Web of Data is a web of interlinked datasets that can be queried and reused through federated query engines. To protect their datasets, data producers use licenses to specify their condition of reuse. But, choosing a compliant license is not easy. Licensing reuse of several licensed datasets must consider compatibility among licenses. To facilitate reuse, federated query engines should preserve license compliance. To do so, we focus on two problems (1) how to compute compatibility relations among licenses, and (2) how to ensure license compliance during federated query processing. To the first problem, we propose CaLi, a model that partially orders any set of licenses in terms of compatibility. To the second problem, we propose FLiQue, a license-aware federated query processing strategy. FLiQue uses CaLi to detect license compatibility conflicts and ensures that the result of a federated query preserves license compliance. Within the scope of this thesis, we also propose three approaches ODMTP, EvaMap, and the SemanticBot that aim to facilitate the integration of datasets to the Web of Data.
