    in Large Language Models Zheng Luo, T Pranav Kutralingam, Ogochukwu N. Okoani, Wanpeng Xu, Hua Wei, Xiyang Hu ACL 2026 読む人:笹野研究室 D2 矢野千紘
  2. BFCL v4 Non-Live, Multipleタスク例 Query: Book a single room for

    two nights at the Hilton Hotel in Chicago, starting from 10th December 2022. Tool List: • “get_stock_price”: "Retrieves the current stock price of the speci ed companies”, • "company_names": {"type": list[str], "description": "The list of companies for which to retrieve the stock price."}} • "currency_converter", : "Calculates the cost in target currency given the amount in base currency and exchange rate" • "base_currency": {"type": "string", "description": "The currency to convert from."}, • "target_currency": {"type": "string", "description": "The currency to convert to."}, • "amount": {"type": " oat", "description": "The amount in base currency”}}, • "book_hotel": "Book a room of speci ed type for a particular number of nights at a speci c hotel, starting from a speci ed date.” • "properties": {"hotel_name": {"type": "string", "description": "The name of the hotel.”} • "location": {"type": "string", "description": "The city in which the hotel is located."}, • "room_type": {"type": "string", "description": "The type of room to be booked."}, • "start_date": {"type": "string", "description": "The start date for the booking."}, • "nights": {"type": "integer", "description": "The number of nights for which the booking is to be made."}} fi fi fi fl fi 6
  3. MLCLの構築 • BFCL v4のNon-Live, Multipleサブセットを複数設定でGPT-5で翻 訳(*詳細は後ほど)、各言語のネイティブによって流暢性、意味 の一貫性を評価 • ただし、クエリを全く同じ意味に保つことが不可能な場合がある •

    「queen‒size bed」が存在しない言語では「大きなベッド」に翻訳 • パラメータ値に「queen‒size bed」が期待されていると常に不正解 • 中国語(表語文字)、ヒンディー語(語順が柔軟)、イボ語(低 リソース)を採用 7
  4. 推論戦略によるエラーの緩和 • PT: ツール呼び出しを作成するプロンプトに、「IMPORTANT: Pass in all parameters in English.」を追加

    • PRE: 事前にクエリを対象のLLMで英語に翻訳する • POST: 事後的にパラーメータ値を対象のLLMで英語に翻訳する 15
