Abstract
LLM-based agents have gained considerable attention for their decision-making skills and ability to handle complex tasks.Recognizing the current gap in leveraging agent capabilities for multiagent collaboration in recommendation systems, we introduce MACRec, a novel framework designed to enhance recommendation systems through multi-agent collaboration.Unlike existing work on using agents for user/item simulation, we aim to deploy multiagents to tackle recommendation tasks directly.In our framework, recommendation tasks are addressed through the collaborative efforts of various specialized agents, including Manager, User/Item Analyst, Reflector, Searcher, and Task Interpreter, with different working flows.Furthermore, we provide application examples of how developers can easily use MACRec on various recommendation tasks, including rating prediction, sequential recommendation, conversational recommendation, and explanation generation of recommendation results.The framework and demonstration video are publicly available at https://github.com/wzf2000/MACRec.
