+==== Marie-Christine ROUSSET: Datalog revisited for reasoning in Linked Data ====
+When: 3rd March 2017, 10h00 \\
+Where: POLYTECH, Templiers 2, room 307\\
+**Abstract**\\
+Linked Data provides access to huge, continuously growing
+amounts of open data and ontologies in RDF format that describe
+entities, links and properties on those entities. Equipping Linked Data
+with inference paves the way to make the Semantic Web a reality. In this
+presentation, I will describe a unifying framework for RDF ontologies
+and databases that we call deductive RDF triplestores. It consists in
+equipping RDF triplestores with Datalog inference rules. This rule
+language allows to capture in a uniform manner OWL constraints that are
+useful in practice, such as property transtivity or symmetry, but also
+domain-specific rules with practical relevance for users in many domains
+of interest. I will illustrate the expressivity of this framework for
+modeling Linked Data applications and its genericity for developing
+inference algorithms. In particular, we will show how it allows to model
+the problem of data linkage in Linked Data as a reasoning problem on
+possibly decentralized data. I will also explain how it makes possible
+to efficiently extract expressive modules from Semantic Web ontologies
+and databases with formal guarantees, whilst effectively controlling
+their succinctness. Experiments conducted on real-world datasets have
+demonstrated the feasibility of this approach and its usefulness in
+practice for data integration and information extraction.
