The authors report evaluating KASB on three popular open-domain Question Answering datasets to demonstrate improved relevance and accuracy. The work targets the semantic space mismatch between queries and retrieved contexts that constrains RAG systems built on large language models.", "body_md": "arXiv:2609.37171v1 Announce Type: new \nAbstract: Retrieval-Augmented Generation has established itself as a fundamental framework in natural language processing, seamlessly integrating information retrieval with the generative capabilities of large language models. However, this process is fundamentally constrained by a critical challenge: semantic space mismatch between queries and retrieved contexts. We propose Knowledge-Aware Semantic Bridging (KASB), a novel framework that improves passage selection quality through semantic space alignment between queries and retrieved documents through intelligent knowledge fusion. Our approach leverages the complementary strengths of generative and retrieval-based knowledge through a multistage process that enhances both relevance and accuracy. We evaluate KASB on three popular open-domain Question Answering datasets to demonstrate the effectiveness of our approach.", "url": "https://wpnews.pro/news/bridging-semantic-gaps-in-rag-through-generated-context-knowledge-fusion", "canonical_source": "https://www.machinebrief.com/news/bridging-semantic-gaps-in-rag-through-generated-context-know-j0cu", "published_at": "2026-09-30 04:00:00+00:00", "updated_at": "2026-09-30 04:47:09.351981+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "natural-language-processing", "ai-research", "generative-ai"], "entities": ["Knowledge-Aware Semantic Bridging", "KASB", "arXiv", "Retrieval-Augmented Generation"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/bridging-semantic-gaps-in-rag-through-generated-context-knowledge-fusion", "markdown": "https://wpnews.pro/news/bridging-semantic-gaps-in-rag-through-generated-context-knowledge-fusion.md", "text": "https://wpnews.pro/news/bridging-semantic-gaps-in-rag-through-generated-context-knowledge-fusion.txt", "jsonld": "https://wpnews.pro/news/bridging-semantic-gaps-in-rag-through-generated-context-knowledge-fusion.jsonld"}}
