YNU-HPCC at SemEval-2026 Task 1: Constraint-Aware In-Context Learning for Multilingual Humor Generation

Xulong Zhang, Jin Wang, Xuejie Zhang


Abstract
This paper describes the system developed by the YNU-HPCC team for SemEval-2026 Task 1 (Humor Generation). The task aims to generate humorous texts from given news headlines or from two unrelated words. The core challenge lies in enabling Large Language Models (LLMs) to understand human humor and align with specific humorous styles. We investigated two approaches: fine-tuning with Proximal Policy Optimization (PPO) and in-context learning with LLMs. We also employed Qwen-Max to evaluate the quality of the generated texts. In the PPO experiments, we constructed a hybrid reward model to align with humor. For our final submission based on LLMs, we used multiple advanced LLMs, along with customized few-shot prompts and a small set of gold samples, to effectively guide the models in generating jokes that resonate with human humor. Experimental results show that our system achieves competitive performance, ranking 4th in the English track, 2nd in the Chinese track, and 2nd in the Spanish track.
