Geoint

Geoint is a comprehensive benchmark dataset explicitly designed for formal geometric problemsolving. Geoint encompasses 1,885 carefully curated geometric questions across diverse categories including plane, spatial, and solid geometry problems. Each problem is richly annotated with both structured textual descriptions and accompanying visual diagrams to support multimodal understanding. Furthermore, Geoint leverages the Lean 4 proof assistant to formally represent geometric elements and relationships, enabling rigorous and complete formal reasoning within a verifiable framework.

You can load the dataset using:


from datasets import load_dataset

dataset = load_dataset("your-username/Geoint", split="train")
