 ## Dataset Details
 
 ### Dataset Description
 
-<!-- Provide a longer summary of what this dataset is. -->
+CommonForms_val is a validation subset extracted from the CommonForms dataset, a web-scale dataset for form field detection introduced in the paper "CommonForms: A Large, Diverse Dataset for Form Field Detection" (Barrow, 2025). The dataset frames form field detection as an object detection problem: given an image of a document page, predict the location and type of form fields.
 
+The full CommonForms dataset was constructed by filtering Common Crawl to find PDFs with fillable elements, starting with 8 million documents and arriving at ~55,000 documents with over 450,000 pages. This validation subset contains 2,500 pages with 34,643 annotated form field instances across diverse languages and domains.
 
+Key characteristics:
+- **Multilingual**: Approximately one-third of pages are non-English
+- **Multi-domain**: 14 classified domains, with no single domain exceeding 25% of the dataset
+- **High-quality annotations**: Automatically extracted from interactive PDF forms with fillable fields
+- **Three form field types**: Text inputs (68.9%), choice buttons (30.7%), and signature fields (0.4%)

 ## Uses
 
-<!-- Address questions around how the dataset is intended to be used. -->
-
 ### Direct Use
 
-<!-- This section describes suitable use cases for the dataset. -->
+This dataset is intended for:
+
+1. **Training and evaluating object detection models** for form field detection in document images
+2. **Benchmarking form field detection systems** against the validation set
+3. **Research in document understanding** and intelligent document processing
+4. **Developing automated form preparation tools** that can convert static PDFs into fillable forms
+5. **Computer vision research** on high-resolution document analysis
+6. **Multi-class object detection** with imbalanced classes (signature fields are rare)
 
-[More Information Needed]
+The dataset is particularly useful for:
+- Training YOLO, Faster R-CNN, or other object detection architectures
+- Fine-tuning vision transformers for document understanding
+- Evaluating model performance across different form field types
+- Studying the impact of high-resolution inputs on detection quality
 
 ### Out-of-Scope Use
 
-<!-- This section addresses misuse, malicious use, and uses that the dataset will not work well for. -->
+This dataset should **not** be used for:
 
-[More Information Needed]
+1. **OCR or text recognition tasks** - The dataset only contains bounding boxes for form fields, not text content
+2. **Form understanding or semantic analysis** - No information about field labels, relationships, or form structure
+3. **Handwriting detection** - Only detects empty form fields, not filled content
+4. **Privacy-sensitive applications without review** - Forms may contain templates with sensitive field types (medical, financial, etc.)
+5. **Production deployment without validation** - This is a validation subset; models should be tested on appropriate test sets
+6. **Fine-grained form field classification** - Only three broad categories are available (text, choice, signature)
 
 ## Dataset Structure
 
-<!-- This section provides a description of the dataset fields, and additional information about the dataset structure such as criteria used to create the splits, relationships between data points, etc. -->
+### FiftyOne Dataset Structure
 
-[More Information Needed]
+This dataset is stored in FiftyOne format, which provides a powerful structure for computer vision datasets:
 
-## Dataset Creation
+**Sample-level fields:**
+- `filepath` (string): Path to the document image file
+- `image_id` (int): Unique identifier for the image from the original dataset
+- `file_name` (string): Original filename (e.g., "0001104-0.png")
+- `dataset_id` (int): Sample ID in the original dataset
+- `ground_truth` (Detections): FiftyOne Detections object containing all form field annotations
 
-### Curation Rationale
+**Detection-level fields (within `ground_truth`):**
+- `label` (string): Form field type - one of:
+  - `text_input`: Text boxes and input fields (68.9% of annotations)
+  - `choice_button`: Checkboxes and radio buttons (30.7% of annotations)
+  - `signature`: Signature fields (0.4% of annotations)
+- `bounding_box` (list): Normalized coordinates [x, y, width, height] in range [0, 1]
+  - Format: [top-left-x, top-left-y, width, height] relative to image dimensions
+- `area` (float): Area of the bounding box in absolute pixels
+- `iscrowd` (bool): COCO-style crowd flag (always False in this dataset)
+- `object_id` (int): Unique identifier for the annotation
+- `category_id` (int): Numeric category (0=text_input, 1=choice_button, 2=signature)
 
-<!-- Motivation for the creation of this dataset. -->
+### Image Specifications
 
-[More Information Needed]
+- **Image dimensions:** Variable, ranging from 1680×1680 to 3360×3528 pixels
+- **Mean dimensions:** 1748×2201 pixels
+- **Format:** RGB PNG images
+- **Resolution:** High-resolution document scans optimized for form field detection
+- **Unique dimensions:** 61 different image size combinations
 
-### Source Data
+### Annotation Format
 
-<!-- This section describes the source data (e.g. news text and headlines, social media posts, translated sentences, ...). -->
+Annotations follow COCO object detection format converted to FiftyOne:
+- **Original format:** COCO [x, y, width, height] in absolute pixel coordinates
+- **FiftyOne format:** Normalized [x, y, width, height] in relative coordinates [0, 1]
+- **Bounding box validation:** Invalid boxes (negative dimensions, out-of-bounds) are filtered during conversion
 
-#### Data Collection and Processing
 
-<!-- This section describes the data collection and processing process such as data selection criteria, filtering and normalization methods, tools and libraries used, etc. -->
+## Dataset Creation
 
-[More Information Needed]
+### Curation Rationale
 
-#### Who are the source data producers?
+The CommonForms dataset was created to address the lack of large-scale, publicly available datasets for form field detection. Existing commercial solutions (Adobe Acrobat, Apple Preview) have limitations:
+- They cannot detect choice buttons (checkboxes/radio buttons)
+- They are closed-source and not reproducible
+- No public benchmarks exist for comparison
 
-<!-- This section describes the people or systems who originally created the data. It should also include self-reported demographic or identity information for the source data creators if this information is available. -->
+The key insight is that "quantity has a quality all its own" - by leveraging existing fillable PDF forms from Common Crawl as a training signal, high-quality form field detection can be achieved without manual annotation. This validation subset enables:
 
-[More Information Needed]
+1. **Reproducible benchmarking** of form field detection systems
+2. **Open-source model development** for automated form preparation
+3. **Research advancement** in document understanding and intelligent document processing
+4. **Cost-effective training** - models trained on this data cost less than $500 in compute

+**Source:** Common Crawl PDF corpus (~8 million PDFs) prepared by the PDF Association
+
+**Filtering Process:**
+1. Started with 8 million PDF documents from Common Crawl
+2. Applied rigorous cleaning to identify well-prepared forms with fillable elements
+3. Filtered to PDFs containing interactive form fields (text boxes, checkboxes, signature fields)
+4. Quality filtering to ensure form fields were properly annotated in the source PDFs
+5. Final dataset: ~55,000 documents with 450,000+ pages
+
+**Processing Steps:**
+1. PDF rendering to high-resolution images (optimized for form field detection)
+2. Extraction of form field annotations from PDF metadata
+3. Conversion to COCO object detection format
+4. Train/validation/test split creation
+5. This subset represents the validation split
+
+**Quality Assurance:**
+- Ablation studies showed the cleaning process improves data efficiency vs. using all PDFs
+- Annotations are automatically extracted from interactive PDF forms (no manual annotation)
+- High-resolution inputs (1216px+) were found crucial for quality detection
+
+**Data Characteristics:**
+- **Multilingual:** ~33% non-English pages
+- **Multi-domain:** 14 domains classified, no domain exceeds 25%
+- **Diverse layouts:** Wide variety of form designs and structures
+- **Real-world forms:** Government forms, applications, surveys, contracts, etc.
 
-[More Information Needed]
+#### Who are the source data producers?
 
-#### Who are the annotators?
+The source data consists of PDF forms published on the public web and crawled by Common Crawl. The original form creators include:
 
-<!-- This section describes the people or systems who created the annotations. -->
+- **Government agencies** (federal, state, local)
+- **Educational institutions**
+- **Healthcare organizations**
+- **Financial institutions**
+- **Legal services**
+- **Corporate entities**
+- **Non-profit organizations**
 
-[More Information Needed]
+The forms were created by professional document designers, administrative staff, and organizations worldwide. The diversity of sources contributes to the dataset's robustness across different form styles, languages, and domains.
 
-#### Personal and Sensitive Information
+**Note:** The forms are templates (unfilled) extracted from publicly available PDFs on the internet.
 
-<!-- State whether the dataset contains data that might be considered personal, sensitive, or private (e.g., data that reveals addresses, uniquely identifiable names or aliases, racial or ethnic origins, sexual orientations, religious beliefs, political opinions, financial or health data, etc.). If efforts were made to anonymize the data, describe the anonymization process. -->
+### Annotations

+#### Annotation process
 
-## Bias, Risks, and Limitations
+**Automatic Annotation from PDF Metadata:**
 
-<!-- This section is meant to convey both technical and sociotechnical limitations. -->
+The annotations in this dataset are **automatically extracted** from interactive PDF forms, not manually annotated. The process:
 
-[More Information Needed]
+1. **Source:** PDF form field metadata embedded in interactive PDFs
+2. **Extraction:** Form field locations and types are programmatically extracted from PDF structure
+3. **Mapping:** PDF form field types are mapped to three detection categories:
+   - PDF text fields → `text_input`
+   - PDF checkbox/radio button fields → `choice_button`
+   - PDF signature fields → `signature`
+4. **Coordinate conversion:** PDF coordinates converted to image pixel coordinates
+5. **Format standardization:** Converted to COCO object detection format
 
-### Recommendations
+**Advantages:**
+- **Scale:** Enables annotation of 450k+ pages without manual labor
+- **Consistency:** Annotations are objective and derived from PDF structure
+- **Cost:** No annotation costs
+- **Quality:** Reflects real-world form field placement by professional designers
 
-<!-- This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->
+**Limitations:**
+- Annotation quality depends on source PDF quality
+- Some PDFs may have incorrectly defined form fields
+- Only detects explicitly defined form fields (not visual-only fields)
 
-Users should be made aware of the risks, biases and limitations of the dataset. More information needed for further recommendations.
+#### Who are the annotators?
 
-## Citation [optional]
+The annotations are **automatically generated** from PDF metadata - there are no human annotators. The "annotators" are effectively the original form designers who created the interactive PDF forms with fillable fields.
 
-<!-- If there is a paper or blog post introducing the dataset, the APA and Bibtex information for that should go in this section. -->
+The dataset curation and extraction pipeline was developed by Joe Barrow (Independent Researcher).
