An Agentic AI-based Multi-Agent Framework for Recommender Systems

Agentic AI describes the use of LLMs in novel AI agents that can answer questions or collaborate to achieve goals. These LLM agents can be used to build a novel generation of recommender systems. However, little is known about the LLM agents or their relationships needed to provide recommendations. Once identified, a framework can be constructed. Moreover, evaluating this framework is still not well understood. In this paper, we propose an agentic AI-based, multi-agent framework for recommender systems. We first identify LLM agents proposed in the literature, followed by the identification of their relationships and we propose a framework to represent them. Next, we evaluate this framework with respect to the LLM agents and functionalities of a recommender system based on published studies. This study is a stepping stone in a novel paradigm shift in the construction of recommender systems.
