+
+This dataset is designed for research in **Deep Learning for Geometry Problem Solving (DL4GPS)** and accompanies the survey paper [A Survey of Deep Learning for Geometry Problem Solving](https://huggingface.co/papers/2507.11936). It aims to provide a structured resource for evaluating and training AI models, particularly multimodal large language models (MLLMs), on mathematical reasoning tasks involving geometric contexts.
+
+The dataset provides a collection of geometry problems, each consisting of a textual question and a corresponding image.
+
+For a continuously updated reading list of papers on Deep Learning for Geometry Problem Solving, refer to the [official GitHub repository](https://github.com/majianz/gps-survey).
+
+## Data Structure
+
+Each problem instance in the dataset includes the following fields:
+
+-   `class`: The category of the geometry problem.
+-   `id`: A unique identifier for each problem.
+-   `question`: The textual description of the geometry problem.
+-   `option`: Multiple-choice options for the answer, if applicable.
+-   `answer`: The correct answer to the geometry problem.
+-   `task_class`: A classification of the task involved.
+-   `Attributes`: Additional attributes or metadata about the problem.
+-   `image`: The image of the geometric diagram associated with the problem.
