OCR-to-text pipelines discard figures, tables and layout, and LVLMs cannot take in many page images at once. Page-retrieval systems such as M3DocRAG and MDocAgent choose pages only by embedding similarity. As a result, they often return… 2. **[Understanding the Behaviors of Environment-aware Information Retrieval](https://md.research.elamur.ai/free/en/papers/yuan-2026-understanding-behaviors-environment-aware-information/)** *(2026)* Agentic RAG systems often assume a single web search engine. In practice, they also query local backends such as BM25 or dense embedders, and each backend may respond best to a differently phrased query. This paper asks whether an LLM query rewriter can learn retriever-specific query styles through reinforcement… ## 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. **[All in One: Multi-Task Prompting for Graph Neural Networks ↗](https://doi.org/10.1145/3580305.3599256) ACM SIGKDD Conference on Knowledge Discovery and Data Mining (KDD) · no summary yet**Xiangguo Sun et al.*2023 · 181 citations* 2. **[MoLoRAG: Bootstrapping Document Understanding via Multi-modal Logic-aware Retrieval](https://md.research.elamur.ai/free/en/papers/wu-2025-molorag-bootstrapping-document-understanding-multi/) [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/)**Xixi Wu, Yanchao Tan, Nan Hou, et al.*2025 · 12 citations* 3. **[Understanding the Behaviors of Environment-aware Information Retrieval](https://md.research.elamur.ai/free/en/papers/yuan-2026-understanding-behaviors-environment-aware-information/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Ruifeng Yuan, Chaohao Yuan, David Dai, et al.*2026* ## Co-authors here 5 co-authors with a page, the most papers together first. - [Chenghao Xiao](https://md.research.elamur.ai/free/en/authors/chenghao-xiao/) - [Hou Pong Chan](https://md.research.elamur.ai/free/en/authors/hou-pong-chan/) - [Ruifeng Yuan](https://md.research.elamur.ai/free/en/authors/ruifeng-yuan/) - [Xixi Wu](https://md.research.elamur.ai/free/en/authors/xixi-wu/) - [Yu Rong](https://md.research.elamur.ai/free/en/authors/yu-rong/) ## 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/) - [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/): [EMNLP 2025](https://md.research.elamur.ai/free/en/venues/emnlp/2025/) - ACM SIGKDD Conference on Knowledge Discovery and Data Mining (KDD) ## Cited by Papers of our library cite their works 41 times (of the 149,439 papers whose bibliographies we read); [19 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/hong-cheng/cited-by/).
