A research paper details a novel approach to conversational music recommendation, presented by the 'swyoo' team for the ACM RecSys Challenge 2026. The system decouples retrieval and response generation, using a hybrid lexical-dense pool and a fine-tuned Qwen 8B adapter for retrieval, with LightGBM for calibration. This method aims to improve explanation credibility by preserving catalog cues and intent through explicit evidence assignment in the response generation phase. AI
