Kohei Matsunobe, a student at ZEN University, developed a Retrieval-Augmented Generation (RAG) demo that allows users to upload Japanese PDFs and ask questions. The system provides answers with citations, indicating the specific file and page number the information was drawn from. Matsunobe prioritized citation accuracy by implementing custom Japanese-aware chunking that prevents chunks from spanning across page boundaries and by instructing the Gemini model to only use provided context and state "I don't know" if the answer is not found.
