# Document OCR Text Tabular Data Notes

## Dataset summary

Preparation notes and schema examples for **Document OCR** tasks using **Text Tabular** data. Full source material is intentionally not bundled, so provenance and licensing remain explicit.

## Included material

- `dataset.py` — loading, cleaning, and split preparation code.
- `dataset_infos.json` — schema and split metadata.
- `metadata_sample.jsonl` — small, human-readable records for checking the schema.
- `README.md` — data card and usage notes.

## Processing choices

| Stage | Setting |
|---|---|
| Storage format | npy sharded |
| Preprocessing | minimal |
| Augmentation | mixup cutmix |
| Split strategy | stratified 90 10 |
| Sampling | balanced |
| Quality checks | strict |
| Labeling | pseudo label |

## Validation checklist

Before using the prepared data, verify source licenses, duplicates across splits, missing values, label balance, and modality-specific corruption. Record the source version and every filtering rule so a later run can reproduce the same rows.

## Intended use

The repository is suitable for testing the data pipeline, adapting it to a documented source, and preparing controlled research splits. Release status: **metadata sample; full source data not bundled**. The sample is for schema inspection only and should not be reported as a full training corpus.

## Risks and limitations

The loader cannot guarantee that an external source is representative, correctly licensed, or free of sensitive information. Users remain responsible for source review, privacy checks, and bias analysis before training or redistribution.
