Intent-aware session recommendation (ISR) is pivotal in discerning user
intents within sessions for precise predictions. Traditional approaches,
however, face limitations due to their presumption of a uniform number of
intents across all sessions. This assumption overlooks the dynamic nature of
user sessions, where the number and type of intentions can significantly vary.
In addition, these methods typically operate in latent spaces, thus hinder the
model's transparency.Addressing these challenges, we introduce a novel ISR
approach, utilizing the advanced reasoning capabilities of large language
models (LLMs). First, this approach begins by generating an initial prompt that
guides LLMs to predict the next item in a session, based on the varied intents
manifested in user sessions. Then, to refine this process, we introduce an
innovative prompt optimization mechanism that iteratively self-reflects and
adjusts prompts. Furthermore, our prompt selection module, built upon the LLMs'
broad adaptability, swiftly selects the most optimized prompts across diverse
domains. This new paradigm empowers LLMs to discern diverse user intents at a
semantic level, leading to more accurate and interpretable session
recommendations. Our extensive experiments on three real-world datasets
demonstrate the effectiveness of our method, marking a significant advancement
in ISR systems.

利用大型语言模型（LLM）的先进推理能力，我们提出了一种新颖的 ISR 方法，通过生成初始提示来引导 LLMs 预测会话中的下一个项目，然后通过迭代自反和调整提示的创新优化机制来完善这个过程，进一步基于 LLMs 的广泛适应能力，我们的提示选择模块快速选择各种领域中最优化的提示，使 LLMs 能够在语义层面上辨别各种用户意图，从而实现更准确和可解释的会话推荐。在三个真实数据集上的广泛实验证明了我们方法的有效性，并在 ISR 系统中取得了重大进展。
