Researchers have developed a region-aware hybrid retrieval method to enhance multilingual question answering, particularly for low-resource languages and culturally specific knowledge. This approach combines traditional lexical matching (BM25) with dense semantic similarity, incorporating regional weighting heuristics to improve answer relevance. The system utilizes a structured prompt for the Qwen3-14B model, employing logit-based deterministic answer selection. While demonstrating improved cross-lingual stability compared to purely parametric inference, the method still faces performance gaps between languages with abundant and scarce training data, indicating that retrieval augmentation does not fully resolve issues of data imbalance.
