MA-RWG: A Multi-Agent Framework for Thematically Structuring and Generation of Related Work

IJCAI 2026

AI-driven survey generation has advanced rapidly, yet related work generation (RWG) remains relatively underexplored. Unlike surveys that provide broad literature overviews, RWG synthesizes prior studies for a single focal paper, requiring contextual fit, cross-paper comparison, and accurate attribu
