| # Document OCR Multimodal3 Data Notes
|
|
|
| ## Overview
|
|
|
| A documented **Document OCR** data-preparation workflow for **Multimodal3** records. The bundled rows demonstrate the schema and validation path rather than pretending to be a full training corpus.
|

|
|
|
| ## Data sources
|
|
|
| 1. external sources are referenced, not redistributed
|
| 2. record retrieval date and filtering rules
|
| 3. keep provenance explicit before any training run
|
|

|
|
| ## Environment
|
|
|
| | Item | Value |
|
| |---|---|
|
| | Python | >= 3.9 |
|
| | torch | 2.x |
|
| | safetensors | any recent |
|

|
|
|
| ## 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.
|

|
|
|
| ## Risks and limitations
|
|
|
| External sources may be unrepresentative, mis-licensed, or contain sensitive fields. Source review, privacy checks and bias analysis are the user's responsibility before training or redistribution.

|
| ## Included material
|
|
|
| 1. `dataloader.py` — loading, cleaning and split preparation.
|
| 2. `dataset_infos.json` — schema and split metadata.
|
| 3. `metadata_sample.jsonl` — readable records for schema checks.

|
|
|
| ## 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.
