Research Interests

• Semantic Interoperability : this topic was initiated by Cheikh A. T. Niang's PhD thesis on the generation of semantic mediators from a reference ontology. It is at the heart of my collaborations with cultural heritage disciplines. It led me to co-create in late 2014 (for 2015) the international workshop Semantic Web for Cultural Heritage, to co-edit the special issue of Semantic Web Journal, and co-chair the international conference SWODCH 2021. This topic requires the design and use of domain ontologies. For Cultural Heritage, the basis for semantic interoperability is the CIDOC CRMwhich does not prevent you from building your own ontology but allows you to make your production interoperable with those of other teams. With the LAT and the MSH Val de Loire, who leads the consortium MASA of the TGIR Huma-Num, I am responsible for the ontologies component of the ANR SESAMES (2018-2022), I participate in the European project H2020 ARIADNEplus (2019-2022) and 4CH (2021-2023). At regional level I was responsible for the IT side of ARVIVA (2014-2016), I'm head of a group on « Semantic Web and interoperability » within RTR DIAMS and I'm involved in a project on digital twins for plains observatory.
• Web of Data Querying : this topic motivated Thanh Binh Nguyen's PhD Thesis (2014-2018). He extended the set of well-known rewriting algorithms (Chase, Chase&BackChase, PerfectRef, Xrewrite) with an efficient solution for the challenge of filtering query results according to a user context. His solution generalises the conditions for triggering the rewriting in the presence of constants in the constraint and in the query, using the notion of one-way MGU. I also consider knowledge graphs querying when contributing to OpenArchaeo, implemented by MASA with Sparna. We study knowledge graphs profiling for allowing humans to query it, and Web applications like Sparnatural to be automatically set up for a given graph.
• Knowledge Extraction from the Web of Data : this theme was initiated in 2016 by a collaboration within my research team with Arnaud Giacometti and Arnaud Soulet, data mining specialists. The idea was to automatically discover the features of knowledge graphs in order to apply data mining algorithms, or more generally to facilitate their exploitation. We devised C3M, a method for mining significant maximum cardinalities, and Versus, which builds from Wikidata a comparison table for a given set of entities.
• We have a PhD funding for next september on l'exploitation des graphes de connaissances du Web des données pour la génération de connaissances stratégiques interprétables: contact me if interested.

Projects

• ANR SESAMES (2018-2022) : Sémantisation Et Spatialisation d'Artefacts patrimoniaux Multi-Echelles : annotation 3D, Sonification et formalisation du raisonnement, led by Jean-Yves Blaise (MAP Marseille), collaboration of CITERES-LAT and LIFAT at Tours, MAP and PRISME at Marseille. The aim is to provide methodological and technical tools to support the scientific study of heritage objects and buildings. In particular, these tools should help in the discovery of relationships between different observations or in the explicitation of a scientific process. Part of the project aims at designing and using a semantic model, composed of several ontologies, to represent domain data and knowledge from architects and archaeologists points of view.
• H2020 ARIADNEplus (2019-2022) : in collaboration with CITERES-LAT within the consortium MASA of the TGIR Huma-Num, to contribute to the development of semantic models for the interoperability of data and services in the field of archaeology in Europe, accessible via a shared platform.
• H2020 4CH (2021-2023) : in collaboration with the Semantic Web team of the MSH Val de Loire's Digital Lab, to contribute to the development of semantic models in support of a European Competence Centre, in conjunction with national Competence Centres, for the digitisation, study and promotion of Cultural Heritage.
