Workshop Overview

Recent advances in AI have ushered in the era of LLMs, transforming the field of NLP. The advancing LLMs are trained on vast multilingual datasets and demonstrate strong performance across a wide range of cross-lingual tasks. The shift toward instruction-based prompting has redefined how users interact with models, expanding the capabilities of pre-trained systems. As a result, LLMs bring both new opportunities and challenges to language processing and information access for diverse linguistic communities. Advanced applications built on multilingual LLMs are rapidly emerging, such as spanning complex tasks, interdisciplinary features, and knowledge-intensive scenarios. This rapid development calls for further exploration by the multilingual and NLP research community.

The goal of the workshop is to develop equitable language technologies for the world's languages to satisfy the needs of users across the globe. In the era of LLMs, two key issues should be addressed: (1) how to construct better multilingual representation learning to mitigate challenges such as the "multilingual curse" and (2) how to develop application solutions based on these models to meet the demands of real-world applications, such as those requiring language-agnostic and context-aware operation.

Call for Papers

Topics

We welcome paper submissions on all topics related to multilingual LLMs, including but not limited to:

  • Multilingualism in the Era of LLMs: Reasoning, Long-Context, Instruction Following, Safety, Reward Modelling, Agentic Systems
  • Training and Adaptation: Data and Algorithms in Pre-Training, Continued Training, Post-Training Alignment
  • Information Access in Multilingualism: Information Retrieval, Embedding Models, Retrieval-Augmented Generation
  • Global Applications of LLMs: Language Education, Finance, Healthcare, Tourism
  • Modalities Beyond Text: Vision, Speech and Sign Language
  • Resources and Benchmarks Across Multilingual Contexts
  • Position or Survey Papers: Insights, Findings and Trends

Submission Guidelines

We welcome two types of papers: Direct Submission and ARR Transfer Submission. All submissions must follow the format requirement of ACL/ARR, and made through OpenReview.


Direct Submission

https://openreview.net/group?id=aclweb.org/ACL/2026/Workshop/MeLLM_Direct_Submission

Submissions of papers must be at most 8 pages (including figures, tables, proofs, appendixes, acknowledgments, and any content except references) in length, with unlimited pages for references.

ARR Transfer Submission

https://openreview.net/group?id=aclweb.org/ACL/2026/Workshop/MeLLM_ARR_Commitment

In addition to papers submitted directly to the workshop, which will be reviewed by our Programme Committee, we also accept papers reviewed through ACL Rolling Review and committed to the workshop. Please check the relevant dates for submission.


While we do not set separate submission tracks for full and short papers, the assessment of each submission will be based on whether the paper length is commensurate with its contribution. For example, a 4-page paper would be accepted if its scientific contribution is worth 4 pages. However, a 8-page paper would be considered weak if it only contains the substance of a 4-page paper. For all accepted papers, we will set Best Paper Award(s), which will be given based on nomination by the reviewers. Accepted papers will be presented as posters with the possibility of oral presentations, and will be included in the workshop proceedings. We also offer a non-archival track to support dual submissions with other venues. Accepted non-archival papers may present at the workshop and appear on the website, but will not be included in official proceedings.


Keynote Speakers

Keynote Speaker 1

Julia Hirschberg - TBA

Julia Hirschberg is Percy K. and Vida L. W. Hudson Professor of Computer Science at Columbia University (department chair from 2012-2018). She previously worked at Bell Laboratories and AT&T Labs on text-to-speech synthesis (TTS) and then created their first HCI Research Department.  She has served on the ACL executive board, the ISCA board (2005-7 as president), the CRA-WP board, the NAACL executive board, the CRA Executive Board, the AAAI Council, and the IEEE SLTC as well as numerous awards committees. She was editor of Computational Linguistics and Speech Communication and is a fellow of AAAI, ISCA, ACL, ACM, and IEEE, and a member of the NAE, the American Academy of Arts and Sciences, the American Philosophical Society, and the National Academy of Artificial Intelligence. She received the IEEE James L. Flanagan Speech and Audio Processing Award, the ISCA Medal for Scientific Achievement and the ISCA Special Service Medal. She studies speech and NLP: TTS; false information on social media and its intent, multimodal humor; radicalization in online videos and social media; charismatic speech; entrainment, emotion and empathy production and recognition in conversation; deceptive, trusted and mistrusted speech; and code-switching in text and speech.
