GroupRank takes a middle path: it splits the candidate pool into small… 2. **[WebClipper: Efficient Evolution of Web Agents with Graph-based Trajectory Pruning](https://md.research.elamur.ai/free/en/papers/wang-2026-webclipper-efficient-evolution-web-agents/)** *(2026)* Open-source Deep Research web agents such as Tongyi-DeepResearch and MiroThinker reach high accuracy on complex information-seeking tasks. ## Co-authors here 12 of 13 co-authors with a page, the most papers together first. - [Dan Yang](https://md.research.elamur.ai/free/en/authors/dan-yang/) ×2 - [Duolin Sun](https://md.research.elamur.ai/free/en/authors/duolin-sun/) ×2 - [Jie Feng](https://md.research.elamur.ai/free/en/authors/jie-feng/) ×2 - [Junjie Wang](https://md.research.elamur.ai/free/en/authors/junjie-wang/) ×2 - [Meixiu Long](https://md.research.elamur.ai/free/en/authors/meixiu-long/) ×2 - [Yihan Jiao](https://md.research.elamur.ai/free/en/authors/yihan-jiao/) ×2 - [Yue Shen](https://md.research.elamur.ai/free/en/authors/yue-shen/) ×2 - [Binbin Hu](https://md.research.elamur.ai/free/en/authors/binbin-hu/) - [Jiahai Wang](https://md.research.elamur.ai/free/en/authors/jiahai-wang/) - [Jian Wang](https://md.research.elamur.ai/free/en/authors/jian-wang/) - [Jinjie Gu](https://md.research.elamur.ai/free/en/authors/jinjie-gu/) - [Lei Liu](https://md.research.elamur.ai/free/en/authors/lei-liu/) ## 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 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) - [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/) Updated 1 November 2026
