Researchers have developed a novel framework called QQ that leverages the inherent duality between question generation and question answering tasks. This framework utilizes a unified architecture that functions as both a multi-hop question generation (MQG) model and a question answering (QA) model, thereby exploiting their interdependence. The QQ framework incorporates bidirectional alignment constraints to ensure a strict mutual correspondence between generated questions and their corresponding answers, alongside contrastive learning to reinforce this relationship. Evaluations on the HotpotQA and MuSiQue datasets indicate that QQ significantly enhances the quality of multi-hop questions. AI
