Can computers be funny? Can humans identify computer-generated humor?

While humor has been studied historically from psychological, cognitive, and linguistic perspectives, its computational study is an active area of research in Machine Learning and Computational Linguistics that has gained traction in recent years. There has been significant development mainly in the field of automatic humor detection and classification, but a characterization of humor that enables its automatic recognition and generation is far from being solved.

This task aims to gain better insight into what is humorous and what causes laughter, and to take some steps forward by assessing the capabilities of current LLMs to generate actual humorous content in Spanish and attempting to see whether it’s possible to automatically distinguish between computer-generated humor and humor written by humans. The target audience is NLP researchers interested in advancing the understanding of highly subjective and creative tasks, though anyone is welcome to participate.

Task description

This year, the HAHA evaluation campaign proposes three different subtasks related to automatic humor detection and generation, with the aim of deepening our understanding of computational humor.

Subtask 1 - Humor Detection: determining if a news headline is satirical or real. The main performance metric for this subtask will be the F1 score of the 'humorous' class. This subtask is similar to the first subtask proposed in previous editions of the HAHA shared task, but this time it's applied to a particular domain where humorous and non-humorous content might sometimes be difficult to tell apart.

Subtask 2 - LLM-generated humor detection: determining if a joke inspired by a news headline was generated by an LLM or written by a human. The main performance metric for this subtask will be the F1 score of the 'automatic' class.

Subtask 3 - Humor Generation: generating jokes from a news headline using computational methods. This subtask will be evaluated through human preference judgments, employing LLM arena-style battles between pairs of generated jokes, and ranking the systems using an Elo-based leaderboard.
