港大与MIT联手打造ItiNera：你的私人AI导游，一键规划完美Citywalk路线！
ItiNera是一个由多所高校联合研发的开放域城市行程规划系统，旨在简化个性化城市漫步的规划过程。它通过结合大型语言模型（LLMs）与空间优化技术，根据用户用自然语言描述的需求，生成定制化的行程规划。ItiNera的核心在于利用LLMs提取和更新兴趣点（POI）特征，构建个性化POI数据库，并通过空间优化和LLM整合，为用户提供连贯、空间上优化的行程建议。该系统在多个数据集上表现突出，实验证明其提供更具响应性和连贯性的行程规划，且在实际应用中已吸引数千用户。ItiNera的开源发布鼓励更多研究者和开发者参与，以进一步优化和拓展城市问题解决方案。
