Span-based approaches handle nesting naturally, but they have four weaknesses: they enumerate many low-quality candidates, which is computationally costly; they cannot reach entities longer than the enumeration limit; they… 3. **[CoT-Valve: Length-Compressible Chain-of-Thought Tuning](https://md.research.elamur.ai/free/en/papers/ma-2025-cot-valve-length-compressible-chain/)** *(2025 · 64 citations)* Reasoning models such as QwQ and DeepSeek-R1 produce long chains of thought even for trivial questions, which wastes tokens. ## Co-authors here 5 co-authors with a page, the most papers together first. - [Gongfan Fang](https://md.research.elamur.ai/free/en/authors/gongfan-fang/) ×2 - [Xinchao Wang](https://md.research.elamur.ai/free/en/authors/xinchao-wang/) ×2 - [Shuai Zhang](https://md.research.elamur.ai/free/en/authors/shuai-zhang/) - [Weiming Lu](https://md.research.elamur.ai/free/en/authors/weiming-lu/) - [Yongliang Shen](https://md.research.elamur.ai/free/en/authors/yongliang-shen/) ## 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/) ×2: [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/), [ACL 2021](https://md.research.elamur.ai/free/en/venues/acl/2021/) - [Conference on Neural Information Processing Systems (NeurIPS)](https://md.research.elamur.ai/free/en/venues/neural-information-processing-systems/): [NeurIPS 2023](https://md.research.elamur.ai/free/en/venues/neural-information-processing-systems/2023/) ## Cited by Papers of our library cite their works 410 times (of the 141,840 papers whose bibliographies we read); [13 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/xinyin-ma/cited-by/).
