PIKE-RAG: sPecIalized KnowledgE and Rationale Augmented Generation
PIKE-RAG is a novel Retrieval-Augmented Generation (RAG) framework designed to overcome limitations of existing RAG systems in industrial applications by focusing on specialized knowledge extraction and rationale construction. It introduces a task classification paradigm to systematically evaluate RAG capabilities and supports phased development. Key innovations include knowledge atomizing and knowledge-aware task decomposition, which enhance performance on complex queries. ✨
