We are pleased to invite submissions for the first Interdisciplinary Workshop on Observations of Misunderstood, Misguided and Malicious Use of Language Models (OMMM 2025). The workshop will be held with the RANLP 2025 conference in Varna, Bulgaria, on 11-13 September 2025.

*Overview* The use of Large Language Models (LLMs) pervades scientific practices in multiple disciplines beyond the NLP/AI communities. Alongside benefits for productivity and discovery, widespread use often entails misuse due to misalignment of values, lack of knowledge, or, more rarely, malice. LLM misuse has the potential to cause real harm in a variety of settings.

Through this workshop, we aim to gather researchers interested in identifying and mitigating inappropriate and harmful uses of LLMs. These include misunderstood usage (e.g., misrepresentation of LLMs in the scientific literature); misguided usage (e.g., deployment of LLMs without adequate training or privacy safeguards); and malicious usage (e.g., generation of misinformation and plagiarism). Sample topics are listed below, but we welcome submissions on any domain related to the scope of the workshop.

*Important Dates* Submission deadline: 6 July 2025, at 23:59 Anywhere on Earth Notification of acceptance: 31 July 2025 Camera-ready papers due: 20 August 2025 Workshop dates: September 11, 12, or 13, 2025

*Submission Guidelines* Submissions will be accepted as short papers (4 pages) and as long papers (8 pages), plus additional pages for references. All submissions undergo a double-blind review, so they should not include any identifying information. Submissions should conform to the RANLP guidelines; for further information and templates, please see https://ranlp.org/ranlp2025/index.php/submissions/

We welcome submissions from diverse disciplines, including NLP and AI, psychology, HCI, and philosophy. We particularly encourage reports on negative results that provide interesting perspectives on relevant topics.

In-person presenters will be prioritised when selecting submissions to be presented at the workshop, but the workshop will take place in a hybrid format. Accepted papers will be included in the workshop proceedings in the ACL Anthology.

Papers should be submitted on the RANLP conference system at https://softconf.com/ranlp25/OMMM2025/

*Keynote Speaker* We are excited to have Dr. Stefania Druga as the keynote speaker for the inaugural OMMM workshop. Dr. Druga is a Research Scientist at Google DeepMind, where she designs novel multimodal AI applications.

*Topics of Interest* We welcome paper submissions on all topics related to inappropriate and harmful uses of LLMs, including but not limited to:

- Misunderstood use (and how to improve understanding): - Misrepresentation of LLMs (e.g., anthropomorphic language) - Attribution of consciousness - Interpretability - Overreliance on LLMs - Misguided use (and how to find alternatives): - Underperformance and inappropriate applications - Structural limitations and ethical considerations - Deployment without proper training or safeguards - Malicious use (and how to mitigate it): - Adversarial attacks, jailbreaking - Detection and watermarking of machine-generated content - Generation of misinformation or plagiarism - Bias mitigation and trust design
