Spotting the Artificial: Dialogic Humor Improvisation in Humans and LLMs

The paper introduces a method to compare human and large language model (LLM) outputs in the context of humorous improvisational dialogue. Using a multi‑agent environment, the authors analyze both automated linguistic metrics and manual annotations based on Systemic Functional Linguistics. Findings reveal that while LLMs can produce coherent and creative scenes, they often lack the spontaneity of human interaction and tend to be overly polite, unlike the varied attitudes seen in human comedy.

Do Personality-Tuned LLMs Make Better Social Agents?

The paper examines whether fine‑tuning large language models (LLMs) with personality‑labelled data improves their ability to act as socially interactive agents. Two small open‑weight LLMs were fine‑tuned on a corpus of personality‑labelled social media posts and dialogues, and the resulting models were evaluated in various social interaction scenarios by independent LLM judges. The findings show that the fine‑tuned models do not outperform their baseline counterparts in role‑playing personalities, though they offer comparable text quality and increased linguistic diversity for the Qwen models; low inter‑rater agreement limits confidence in the results, suggesting future work should focus on training data quality and domain alignment.

MultiHuSE: A Multimodal Dataset for Humour Styles and Emotions

MultiHuSE is a multimodal dataset featuring 2,407 high‑definition videos of 50 diverse actors delivering 1,463 text samples in four psychological humour styles—affiliative, aggressive, self‑enhancing, and self‑deprecating—plus neutral content. Each text is performed by multiple actors, allowing analysis of expressive diversity, and a subset includes emotion annotations. Baseline experiments show that multimodal fusion improves humour style classification accuracy over unimodal approaches, especially for affiliative humour.
