1. **[Re2G: Retrieve, Rerank, Generate](https://md.research.elamur.ai/free/en/papers/glass-2022-re2g-retrieve-rerank-generate/)** *(2022 · 184 citations)* Retrieval-augmented generators such as RAG and REALM let a model draw on a large passage corpus instead of storing all its knowledge in parameters.
2. **[PaniniQA: Enhancing Patient Education Through Interactive Question Answering](https://md.research.elamur.ai/free/en/papers/cai-2023-paniniqa-enhancing-patient-education-through/)** *(2023 · 24 citations)* Patients leaving hospital often struggle to grasp or remember their discharge instructions, and their misreadings usually go uncorrected. PaniniQA addresses this with a chatbot that quizzes patients about their own instructions. It follows the Prompt–Evaluate–Expand–Repeat (P.E.E.R.) cycle from Dialogic Reading.
