MWAHAHA - Models Write Automatic Humor And Humans Annotate at SemEval
2026 (Task 1)
https://pln-fing-udelar.github.io/semeval-2026-humor-gen/
While Humor Understanding has been the focus of many shared tasks, Humor
Generation remains an even more challenging and largely unexplored
frontier. MWAHAHA, which stands for Models Write Automatic Humor And
Humans Annotate, is SemEval 2026's Task 1 [1] and is the first task
dedicated to advancing the state of the art in Computational Humor
Generation. We invite participants to develop systems capable of
generating genuinely humorous content under various constraints.
Our goal is to push models beyond memorization and towards true humorous
creativity. By using carefully designed constraints, we aim to ensure
fairness in evaluation and encourage the generation of novel jokes. This
task has significant implications for more engaging conversational AI,
creative writing tools, and a deeper understanding of the complex nature
of humor itself.
The task is organized into two subtasks:
*
Subtask A: Text-based Humor Generation
Systems must generate jokes following constraints (related to a news
headline, or containing certain words). This subtask is in English,
Spanish, and Chinese.
*
Subtask B: Image-Based Caption Generation
Systems must generate a free-form humorous caption given a GIF image
that enhances its comedic effect. This subtask is in English only.
The participating systems will be evaluated based on human preferences
on 1-on-1 arena-style battles.
