Talk to Right Specialists: Iterative Routing in Multi-agent Systems for Question Answering

ArXi:2501.07813v2 Announce Type: replace-cross Retrieval-augmented generation (RAG) agents are increasingly deployed to answer questions over local knowledge bases that cannot be centralized due to knowledge-sovereignty constraints. This results in two recurring failures in production: users do not know which agent to consult, and complex questions require evidence distributed across multiple agents. To overcome these challenges, we propose RIRS, a
