Current projects
Orange
-
AI4Sec, exploring how AI can enhance the security of networks and operations (2025 - ongoing).
Related on-line resources,
- DSecO, an RDF data model for DNS configuration assessment.
-
Knowledge Graphs at the company scale (2025 - on-going).
See the “I want a KG-based Digital Twin, and that’s all I (want to) know” presentation (2024) [pres-pdf] made at the KG4DI workshop for an overview of the challenges to be addressed.
Related on-line resources,
- Ontology2Graph, generating synthetic knowledge graphs using generative AI and graph fusion, taking an RDFS/OWL ontology as input.
- PyGraft-gen, generating synthetic knowledge graphs using a stochastic approach, taking an RDFS/OWL ontology as input. Post-generation graph matching helps assess the adequacy of the knowledge graph for a specific application domain.
