1. ReARTeR: Retrieval-Augmented Reasoning with Trustworthy Process Rewarding (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 (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 (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 (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 (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…
