1. **[ReARTeR: Retrieval-Augmented Reasoning with Trustworthy Process Rewarding](https://md.research.elamur.ai/free/en/papers/sun-2025-rearter-retrieval-augmented-reasoning-trustworthy/)** *(2025 · 22 citations)* Retrieval-augmented generation (RAG) pipelines still struggle with questions that require several chained reasoning and lookup steps.
2. **[A Joint Model for Dropped Pronoun Recovery and Conversational Discourse Parsing in Chinese Conversational Speech](https://md.research.elamur.ai/free/en/papers/yang-2021-joint-model-dropped-pronoun-recovery/)** *(2021 · 16 citations)* Chinese speakers frequently omit pronouns that listeners can infer from context. Existing systems handle two related problems separately: dropped pronoun recovery (DPR), which finds where a pronoun is missing and what type it is, and conversational discourse parsing (CDP), which links utterances through relations…
3. **[MatchTIR: Fine-Grained Supervision for Tool-Integrated Reasoning via Bipartite Matching](https://md.research.elamur.ai/free/en/papers/qu-2026-matchtir-fine-grained-supervision-tool/)** *(2026 · 1 citation)* Reinforcement learning for tool-integrated reasoning (TIR) in LLMs usually rewards whole outcomes or trajectories.
4. **[Fine-Mem: Fine-Grained Feedback Alignment for Long-Horizon Memory Management](https://md.research.elamur.ai/free/en/papers/ma-2026-fine-mem-fine-grained-feedback/)** *(2026)* LLM agents working on long-horizon tasks need a memory system that turns a stream of incoming text chunks into a compact, usable store.
5. **[When Personalization Misleads: Understanding and Mitigating Hallucinations in Personalized LLMs](https://md.research.elamur.ai/free/en/papers/sun-2026-when-personalization-misleads-understanding-mitigating/)** *(2026)* The paper examines an overlooked risk of personalized LLMs. When a model is conditioned on a user's chat history or profile, it may answer factual questions in line with what the user said before instead of with the truth. The authors call this failure "personalization-induced hallucination." They attribute it to…
