TaoData

Dataset Summary

TaoData is a large-scale English pretraining dataset prepared for the Taotern model family. It is a processed subset of HuggingFaceFW/fineweb-edu, filtered and formatted with the TaoData framework using the taodata.yaml configuration.

This release contains about 6.7 million samples in JSONL format and is intended as one of the main pretraining corpora used by Taotern models.

Supported Tasks

• Causal language modeling
• Continued pretraining
• Data mixture construction for foundation models

Languages

• English

Source Data

This dataset is derived from:

• HuggingFaceFW/fineweb-edu

The upstream dataset is a large English web corpus derived from Common Crawl and released by Hugging Face. TaoData applies the TaoData preprocessing pipeline to produce a cleaned training subset suitable for large-scale language model pretraining.

Processing

The dataset was processed with the TaoData framework using:

• taodata/config/taodata.yaml

At a high level, this release is intended to be a clean, training-ready subset for Taotern model development.

Intended Use

TaoData is designed for:

• Pretraining or continued pretraining of large language models
• Training data ablations and mixture experiments
• Research on web-scale text filtering and corpus construction

Limitations

• This is web-derived text and may still contain factual errors, bias, noise, or unwanted content.
• The dataset inherits limitations, source coverage, and potential artifacts from FineWeb-Edu and Common Crawl.
• It is intended for research and model training, not as a source of verified facts.

Licensing

This dataset is derived from FineWeb-Edu, which is published on Hugging Face under the odc-by license at the time of writing. Users should review the upstream dataset card and ensure their use complies with all applicable upstream terms and attribution requirements.
