A hybrid fact-checking system combining predicate-logic rules, ontologies (OWL), and neuro-symbolic AI to evaluate the credibility of information sources.

SysCRED est un système hybride de fact-checking combinant :

• Symbolic AI : Raisonnement par règles et ontologies (OWL/RDF)

• Neural AI : Transformers pour NER, sentiment, cohérence

• IR Engine : Recherche d’évidence (BM25, TF-IDF, TREC)

• GraphRAG : Mémoire contextuelle par graphe de connaissances

• E-E-A-T : Scoring qualité Google (Experience, Expertise, Authority, Trust)

• Technologies: Python, NLP, OWL Ontologies, Machine Learning, Neuro-symbolic AI

• Status: Active Research (Doctoral Project)

• 📂 Repository

• 📄 Modeling Paper

• 📄 Ontology Paper

• 📄 Beamer Presentation - (PDF)
