Earlier work showed this behaviour can be triggered with little data and carries over to new tasks. This paper asks whether long CoT is a general capability already present inside LLMs. 2. **[GroupRank: A Groupwise Paradigm for Effective and Efficient Passage Reranking with LLMs](https://md.research.elamur.ai/free/en/papers/long-2026-grouprank-groupwise-paradigm-effective-efficient/)** *(2026)* LLM rerankers face a trade-off between accuracy and speed. Pointwise scoring is fast but never compares documents with each other. Listwise ranking does compare them, but it exceeds context limits and relies on slow sequential sliding windows. GroupRank takes a middle path: it splits the candidate pool into small… ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[Heterogeneous Graph Structure Learning for Graph Neural Networks ↗](https://doi.org/10.1609/aaai.v35i5.16600) Proceedings of the AAAI Conference on Artificial Intelligence · no summary yet**Jianan Zhao et al.*2021 · 289 citations* 2. **[Unlocking General Long Chain-of-Thought Reasoning Capabilities of Large Language Models via Representation Engineering](https://md.research.elamur.ai/free/en/papers/tang-2025-unlocking-general-long-chain-thought/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Xinyu Tang, Xiaolei Wang, Zhihao Lv, et al.*2025 · 19 citations* 3. **[GroupRank: A Groupwise Paradigm for Effective and Efficient Passage Reranking with LLMs](https://md.research.elamur.ai/free/en/papers/long-2026-grouprank-groupwise-paradigm-effective-efficient/) [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/)**Meixiu Long, Duolin Sun, Dan Yang, et al.*2026* ## Co-authors here 12 of 15 co-authors with a page, the most papers together first. - [Dan Yang](https://md.research.elamur.ai/free/en/authors/dan-yang/) - [Duolin Sun](https://md.research.elamur.ai/free/en/authors/duolin-sun/) - [Jiahai Wang](https://md.research.elamur.ai/free/en/authors/jiahai-wang/) - [Jie Feng](https://md.research.elamur.ai/free/en/authors/jie-feng/) - [Junjie Wang](https://md.research.elamur.ai/free/en/authors/junjie-wang/) - [Lei Liu](https://md.research.elamur.ai/free/en/authors/lei-liu/) - [Meixiu Long](https://md.research.elamur.ai/free/en/authors/meixiu-long/) - [Wayne Xin Zhao](https://md.research.elamur.ai/free/en/authors/wayne-xin-zhao/) - [Xiaolei Wang](https://md.research.elamur.ai/free/en/authors/xiaolei-wang/) - [Xinyu Tang](https://md.research.elamur.ai/free/en/authors/xinyu-tang/) - [Yihan Jiao](https://md.research.elamur.ai/free/en/authors/yihan-jiao/) - [Yingqian Min](https://md.research.elamur.ai/free/en/authors/yingqian-min/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/): [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/) - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) - Proceedings of the AAAI Conference on Artificial Intelligence ## Cited by Papers of our library cite their works 26 times (of the 149,439 papers whose bibliographies we read); [7 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/binbin-hu/cited-by/).
