## Papers

The most cited first (OpenAlex and our library).

1. **[PEEP-Talk: A Situational Dialogue-based Chatbot for English Education](https://md.research.elamur.ai/free/en/papers/lee-2023-peep-talk-situational-dialogue-based/)** *(2023 · 9 citations)* Learners of English as a foreign language rarely get to practise realistic conversation. Existing tutoring chatbots tend to be rule-based, cope poorly with off-topic input, and give little feedback. PEEP-Talk addresses this with three parts:
2. **[HiKEY: Hierarchical Multimodal Retrieval for Open-Domain Document Question Answering](https://md.research.elamur.ai/free/en/papers/shin-2026-hikey-hierarchical-multimodal-retrieval-open/)** *(2026)* The paper tackles retrieval-augmented question answering over large collections of long, multi-page PDFs. Such documents mix prose with tables and figures, and systems often fail in two ways: they pick the wrong document from thousands of candidates, or they return evidence fragments that stay disconnected. Standard…
3. **[I Don't Need Solution. I Need Emotional Support : Empathetic LLMs based on Emotional Validation](https://md.research.elamur.ai/free/en/papers/son-2026-i-don-t-need-solution/)** *(2026)* LLMs used as emotional-support chatbots tend to jump straight to advice. They repeat stock phrases and ignore how the help-seeker's feelings evolve over a dialogue. In a pilot study on ESConv, crowd workers judged most Mistral and GPT-4o replies as not comforting. To fix this, the authors propose EVA, a framework…
4. **[NeedleChain: Measuring Intact Context Comprehension Capability of Large Language Models](https://md.research.elamur.ai/free/en/papers/moon-2026-needlechain-measuring-intact-context-comprehension/)** *(2026)* Long-context benchmarks for LLMs usually mix a small amount of query-relevant evidence with a lot of filler, as in the needle-in-a-haystack (NIAH) setup.
