5ting at SemEval-2026 Task 8: Strong End-to-End Multi-Turn RAG via LLM-Based Reranking and Faithfulness Control
The authors introduce 5ting, a system designed for the SemEval-2026 Task 8 (MTRAGEval) which evaluates multi-turn Retrieval Augmented Generation (RAG) systems. The system addresses challenges such as context drift, under specification, and hallucination risk by combining dense retrieval with LLM-based reranking and faithfulness control.
