# CommonForms: A Large, Diverse Dataset for Form Field Detection
This repository hosts the **CommonForms** dataset, a web-scale dataset for form field detection, introduced in the paper [CommonForms: A Large, Diverse Dataset for Form Field Detection](https://huggingface.co/papers/2509.16506).
CommonForms casts the problem of form field detection as object detection: given an image of a page, predict the location and type (Text Input, Choice Button, Signature) of form fields.
**Key Features:**
* **Scale:** Roughly 55,000 documents comprising over 450,000 pages.
* **Source:** Constructed by filtering Common Crawl to find PDFs with fillable elements.
* **Diversity:** Contains a diverse mixture of languages (one third non-English) and domains, with no single domain making up more than 25% of the dataset.
* **Purpose:** The first large-scale dataset released for form field detection, aimed at fostering the development of robust form field detectors.
