# English Document Format Classification Dataset

English-language web pages classified by document type, designed to train robust text classifiers and provide ready-to-use data for specific web formats.

* **Purpose:** Train generalized document classifiers or extract clean, single-format corpora for specific downstream tasks.
* **Configurations:** Each document type is available in its own dedicated dataset configuration (e.g., `TutorialHow-ToGuide`, `PersonalAboutPage`).
* **Splits:** The `All` configuration contains every document type combined, featuring a 10% stratified test split.

## Curation & Filtering Pipeline

This dataset is derived from a subset of the first 1 million rows of [`allenai/c4`](https://huggingface.co/datasets/allenai/c4), utilizing annotations from [`agentlans/en-document-classification`](https://huggingface.co/datasets/agentlans/en-document-classification).

1. **Filtering:** Samples are included only when the `weborganizer_format` field matches `doc_type_v2_primary`.
2. **Personally identifiable information (PII) removal:** Samples were removed based on [`agentlans/multilingual-e5-small-pii-detector`](https://huggingface.co/agentlans/multilingual-e5-small-pii-detector).
