港大與MIT聯手打造ItiNera：你的私人AI導遊，一鍵規劃完美Citywalk路線！
ItiNera是一個由多所高校聯合研發的開放域城市行程規劃系統，旨在簡化個性化城市漫步的規劃過程。它通過結合大型語言模型（LLMs）與空間優化技術，根據用戶用自然語言描述的需求，生成定製化的行程規劃。ItiNera的核心在於利用LLMs提取和更新興趣點（POI）特徵，構建個性化POI數據庫，並通過空間優化和LLM整合，爲用戶提供連貫、空間上優化的行程建議。該系統在多個數據集上表現突出，實驗證明其提供更具響應性和連貫性的行程規劃，且在實際應用中已吸引數千用戶。ItiNera的開源發佈鼓勵更多研究者和開發者參與，以進一步優化和拓展城市問題解決方案。
