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… 2. **[Agent-Pro: Learning to Evolve via Policy-Level Reflection and Optimization](https://md.research.elamur.ai/free/en/papers/zhang-2024-agent-pro-learning-evolve-policy/)** *(2024 · 52 citations)* Most LLM-based agents depend on hand-written prompts that fix task rules and behavior. They cannot improve through experience, so they struggle in dynamic multi-agent settings with hidden information. Agent-Pro tackles this by treating policy learning as gradient-free prompt optimization, with no parameter updates. ## All works 4 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. **[Locate and Label: A Two-stage Identifier for Nested Named Entity Recognition](https://md.research.elamur.ai/free/en/papers/shen-2021-locate-label-two-stage-identifier/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Yongliang Shen, Xinyin Ma, Zeqi Tan, et al.*2021 · 232 citations* 2. **[Parallel Instance Query Network for Named Entity Recognition ↗](https://aclanthology.org/2022.acl-long.67/) Proceedings of the 60th Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers) · no summary yet**Yongliang Shen et al.*2022 · 98 citations* 3. **[PromptNER: Prompt Locating and Typing for Named Entity Recognition ↗](https://aclanthology.org/2023.acl-long.698/) Proceedings of the 61st Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers) · no summary yet**Yongliang Shen et al.*2023 · 83 citations* 4. **[Agent-Pro: Learning to Evolve via Policy-Level Reflection and Optimization](https://md.research.elamur.ai/free/en/papers/zhang-2024-agent-pro-learning-evolve-policy/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Wenqi Zhang, Ke Tang, Hai Wu, et al.*2024 · 52 citations* ## Co-authors here 10 co-authors with a page, the most papers together first. - [Weiming Lu](https://md.research.elamur.ai/free/en/authors/weiming-lu/) ×2 - [Yongliang Shen](https://md.research.elamur.ai/free/en/authors/yongliang-shen/) ×2 - [Guiyang Hou](https://md.research.elamur.ai/free/en/authors/guiyang-hou/) - [Mengna Wang](https://md.research.elamur.ai/free/en/authors/mengna-wang/) - [Peng Li](https://md.research.elamur.ai/free/en/authors/peng-li/) - [Shuai Zhang](https://md.research.elamur.ai/free/en/authors/shuai-zhang/) - [Wen Wang](https://md.research.elamur.ai/free/en/authors/wen-wang/) - [Wenqi Zhang](https://md.research.elamur.ai/free/en/authors/wenqi-zhang/) - [Xinyin Ma](https://md.research.elamur.ai/free/en/authors/xinyin-ma/) - [Yueting Zhuang](https://md.research.elamur.ai/free/en/authors/yueting-zhuang/) ## 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/) ×4: [ACL 2024](https://md.research.elamur.ai/free/en/venues/acl/2024/), [ACL 2021](https://md.research.elamur.ai/free/en/venues/acl/2021/) ## Cited by Papers of our library cite their works 139 times (of the 149,439 papers whose bibliographies we read); [13 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/zeqi-tan/cited-by/).
