♟️ Chess1K-VQA

👁️‍🗨️ A Chessboard Visual Question Answering Dataset for Vision–Language Models

Chess1K-VQA is a synthetic Visual Question Answering (VQA) dataset built using programmatically generated chessboard images. The dataset is designed to evaluate vision–language models (VLMs) on spatial grounding, visual perception, and basic rule-based reasoning in a controlled and fully deterministic domain.

📦 Dataset Details

🧩 Dataset Description

Chess1K-VQA consists of 1,000 rendered chessboard images generated using the open-source Python Chess library. Each image is paired with a natural-language question and a deterministic ground-truth answer derived from the underlying chess position.

The dataset supports tasks such as piece identification, square occupancy, check/checkmate detection, castling rights, turn recognition, and piece counting.

🛠️ Uses

✅ Direct Use

Zero-shot and few-shot evaluation of vision–language models
Visual–symbolic reasoning research
Spatial grounding and coordinate understanding (e.g., “square c2”)
Multimodal instruction-following evaluation
Accessibility tools for visually impaired or physically challenged users
Educational and benchmarking purposes

🚫 Out-of-Scope Use

Chess engine training or competitive gameplay optimization
Predicting optimal moves or winning strategies
Real-world scene understanding
Tasks requiring natural image diversity

🧱 Dataset Structure

The dataset is provided as a Hugging Face DatasetDict with predefined splits:

🟢 Train: 800 samples
🔵 Test: 200 samples

Each sample contains:

id — unique identifier
image — rendered chessboard image
question — natural-language question
answer — ground-truth answer
fen — Forsyth–Edwards Notation of the position

🏗️ Dataset Creation

🎯 Curation Rationale

The dataset was created to provide a clean, reproducible benchmark for evaluating vision–language models on structured visual reasoning tasks. Chess offers a well-defined visual layout and deterministic rules, making it ideal for controlled evaluation.

🧪 Source Data

⚙️ Data Collection and Processing

Chess positions were generated programmatically using the Python Chess library. Each position was rendered into an image using standard visualization tools. Questions and answers were automatically generated using rule-based logic.

👨‍💻 Who are the source data producers?

All data was synthetically generated by scripts authored by the dataset creators. No external datasets or human subjects were involved.

🏷️ Annotations

🧠 Annotation Process

Annotations were generated automatically using deterministic rules derived from the chess position. No manual annotation was performed.

👥 Who are the annotators?

Annotations were produced programmatically by the dataset generation system.

🔐 Personal and Sensitive Information

The dataset does not contain any personal, sensitive, or private information.

⚠️ Bias, Risks, and Limitations

Limited to rendered chessboard images
Does not represent natural image variability
Evaluates structured reasoning, not strategic gameplay

📌 Recommendations

Users should treat this dataset as a benchmark for visual–symbolic reasoning and spatial grounding, not as a general-purpose vision dataset.
