Most memory systems store past turns as embeddings and fetch them by semantic similarity alone, so they miss links between memories that are related through shared history rather than wording. HeLa-Mem addresses this with a memory design… 4. **[All Languages Matter: Understanding and Mitigating Language Bias in Multilingual RAG](https://md.research.elamur.ai/free/en/papers/wang-2026-all-languages-matter-understanding-mitigating/)** *(2026 · 1 citation)* Multilingual RAG (mRAG) systems can draw on documents written in many languages. This paper shows that the reranking step skews heavily toward English and toward the language of the query, so relevant evidence in other languages tends to be ignored. To test this, the authors built a pipeline over a 13-language… ## All works 5 works of theirs in our library, the most cited first; 4 with a page here, the others link their original until we summarise them. 1. **[HalluLens: LLM Hallucination Benchmark](https://md.research.elamur.ai/free/en/papers/bang-2025-hallulens-llm-hallucination-benchmark/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Yejin Bang, Ziwei Ji, Alan Schelten, et al.*2025 · 82 citations* 2. **[Calibrating Verbal Uncertainty as a Linear Feature to Reduce Hallucinations](https://md.research.elamur.ai/free/en/papers/ji-2025-calibrating-verbal-uncertainty-as-linear/) [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/)**Ziwei Ji, Lei Yu, Yeskendir Koishekenov, et al.*2025 · 11 citations* 3. **[HeLa-Mem: Hebbian Learning and Associative Memory for LLM Agents](https://md.research.elamur.ai/free/en/papers/zhu-2026-hela-mem-hebbian-learning-associative/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Jinchang Zhu, Jindong Li, Cheng Zhang, et al.*2026 · 2 citations* 4. **[All Languages Matter: Understanding and Mitigating Language Bias in Multilingual RAG](https://md.research.elamur.ai/free/en/papers/wang-2026-all-languages-matter-understanding-mitigating/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Dan Wang, Guozhao Mo, Yafei Shi, et al.*2026 · 1 citation* 5. **[DarwinTOD: LLM-Driven Lifelong Self-evolution for Task-oriented Dialog Systems ↗](https://aclanthology.org/2026.acl-long.2050/) Proceedings of the 64th Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers) · no summary yet**Shuyu Zhang et al.*2026* ## Co-authors here 12 of 20 co-authors with a page, the most papers together first. - [Alan Schelten](https://md.research.elamur.ai/free/en/authors/alan-schelten/) ×2 - [Anthony Hartshorn](https://md.research.elamur.ai/free/en/authors/anthony-hartshorn/) ×2 - [Nicola Cancedda](https://md.research.elamur.ai/free/en/authors/nicola-cancedda/) ×2 - [Pascale Fung](https://md.research.elamur.ai/free/en/authors/pascale-fung/) ×2 - [Yejin Bang](https://md.research.elamur.ai/free/en/authors/yejin-bang/) ×2 - [Ziwei Ji](https://md.research.elamur.ai/free/en/authors/ziwei-ji/) ×2 - [Ben He](https://md.research.elamur.ai/free/en/authors/ben-he/) - [Bo Zheng](https://md.research.elamur.ai/free/en/authors/bo-zheng/) - [Boxi Cao](https://md.research.elamur.ai/free/en/authors/boxi-cao/) - [Guozhao Mo](https://md.research.elamur.ai/free/en/authors/guozhao-mo/) - [Hongyu Lin](https://md.research.elamur.ai/free/en/authors/hongyu-lin/) - [Jiahong Liu](https://md.research.elamur.ai/free/en/authors/jiahong-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/) ×4: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) ×2, [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/) - [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/) ## Cited by Papers of our library cite their works 53 times (of the 149,439 papers whose bibliographies we read); [15 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/cheng-zhang/cited-by/).
