Event Notification Type: Call for Participation
We kindly invite you to participate at the MiMIC: Multi-Modal AI Content Moderation shared task organized under the Iberian Language Evaluation Forum (IberLEF) 2025https://sites.google.com/view/iberlef-2025 which will be held in Zaragoza (Spain) on September 2025.
This shared task focuses on the problem of detecting whether a text-image pair is partially or completely generated by generative models like GPT, Stable Diffusion, and others. We hope to understand whether multi-modal framing can improve the performance of generated content detectors.
MiMIC consists of two subtasks focused on the same detection task, both for English and Spanish. Both subtasks involve multiclass classification of (text, image) pairs into four categories: fully-generated, fully-human, image-generated, and text-generated.
* Subtask 1: Multimodal Machine Generated Content Detection in English. * Subtask 2: Multimodal Machine Generated Content Detection in Spanish.
This shared task is open to everyone! We do not constrain the target community allowing participation from students to companies.
