A Knowledge Graph-Augmented Large Language Model Framework for Context-Aware Question-Answering and Intelligent Feedback Generation

Bihter Daş, Pınar Savcı, Tunahan Gökçimen, Müzeyyen Bulut Özek

This study proposes EQAS (Empowered Question-Answering System), a hybrid framework designed to support context-aware question-answering and intelligent feedback generation in domain-specific knowledge environments. EQAS integrates fine-tuned transformer-based models, instruction-guided large language models, domain-specific knowledge graphs, and LangChain-based vector retrieval to improve contextual …

A Privacy-Conscious and Explainable IDS-Oriented Triage and Response Pipeline for Mobile Network Infrastructure Using Aggregated Cellular Traffic Signatures

Ozcan Dimez, Fatih Çögen

Mobile-network operators must interpret spatial anomalies in aggregated cell-level telemetry and decide whether, where, and how to respond. This paper presents a privacy-conscious, intrusion detection system (IDS)-oriented triage and response architecture that consumes cell-level anomaly signatures and couples spatial reconstruction, short-horizon forecasting, …

ML-driven network orchestrator for 6G O-RAN: Resolving multi-xApp conflicts in near-RT RIC

Can Kurtulan, Onur Kalinagac, Erdinc Ozdemir, Burak Görkemli et autres

The evolution toward 6G networks necessitates a shift toward fully automated, AI-native, and zero-touch operational solutions to handle unprecedented network complexity. Within the Open RAN (O-RAN) architecture, the near-Real-Time RAN Intelligent Controller (near-RT RIC) plays a pivotal role in hosting third-party xApps …
