OntoLogX: Ontology-Guided Knowledge Graph Extraction from Cybersecurity Logs with Large Language Models

01 October 2025 Luca Cotti, Idilio Drago, Anisa Rula, Devis Bianchini, Federico Cerutti

OntoLogX studies how to extract knowledge graphs from cybersecurity logs using LLMs guided by domain ontologies, imposing semantic structure on noisy and fragmented evidence.

It links CTI, log analytics, ontologies, and language models in a way that can directly support investigation, correlation, and explainability.
