DeliChess: A Multi-party Dialogue Dataset for Deliberation in Chess Puzzle Solving

arXiv:2606.04987v1 Announce Type: cross Abstract: Multi-party dialogue is a critical setting for studying collaborative reasoning and decision-making, yet existing datasets rarely focus on structured, in-depth complex reasoning tasks. We introduce DeliChess, a novel dataset of group deliberation dialogues in which participants collaboratively solve multiple-choice chess puzzles. Each group first completes the puzzle individually, then engages in a multi-party discussion before submitting a revised collective answer. The dataset includes 107 dialogues with full transcripts, pre- and post-discus

Why this matters
Why now

The continuous growth in AI research necessitates more complex and nuanced datasets to train advanced models, especially in collaborative reasoning and deliberation tasks.

Why it’s important

Sophisticated AI systems require datasets that reflect real-world collaborative problem-solving, moving beyond simple Q&A to multi-party deliberation for improved decision-making capabilities.

What changes

This dataset offers a new resource for developing AI models capable of understanding, participating in, and potentially facilitating complex group discussions and decision-making processes.

Winners
