BAHAHA at SemEval-2026 Task 1: Benchmarking-Aware Humor Authoring with Hybrid Assessment and Adaptation

· Source: Paper Index on ACL Anthology · Field: Technology & Digital — Artificial Intelligence & Machine Learning · Depth: Expert, short

Summary

The BAHAHA system, developed by Utsav Arora and Andrew Hoblitzell for SemEval-2026 Task 1: MWAHAHA, generates original jokes from news headlines or rare word pairs. This system employs a generate-then-rank pipeline, utilizing multi-style candidate generation through comedian-inspired few-shot prompting. Quality assessment is performed by a smaller model fine-tuned on synthetic rating data from the generation model. BAHAHA produces up to 50 candidates per input across 15 stylistic templates, selecting outputs via a mixed-initiative interface combining automated ranking with human judgment. In a contest with 305 participants and 180 submissions, BAHAHA ranked 2nd on Subtask A Chinese and 5th on Subtasks B1 and B2, generating jokes natively in each language.

Key takeaway

For NLP Engineers developing creative text generation systems, consider adopting a generate-then-rank architecture to enhance output quality and diversity. Your systems can benefit from multi-style candidate generation via few-shot prompting and a smaller, fine-tuned model for initial quality assessment. Integrating human judgment into the final selection process, as demonstrated by BAHAHA's success in SemEval-2026, is crucial for subjective tasks like humor authoring.

Key insights

A hybrid generate-then-rank pipeline effectively creates multi-style humor using few-shot prompting and synthetic data for quality assessment.
