| # CleanedFineWeb2Edu-jp |
|
|
| CleanedFineWeb2Edu-jp is a cleaned Japanese web text dataset. |
|
|
| This dataset was created from the `sample_10BT` subset of |
| [`hotchpotch/fineweb-2-edu-japanese`](https://huggingface.co/datasets/hotchpotch/fineweb-2-edu-japanese). |
| The source text was refined with |
| [`MK0727/corpus-refiner-jp`](https://huggingface.co/MK0727/corpus-refiner-jp). |
|
|
| ## Purpose |
|
|
| The main purpose of this dataset is to provide cleaner Japanese web text for |
| language model pretraining and continued pretraining. |
|
|
| This dataset keeps Japanese web documents from FineWeb2-Edu while reducing |
| boilerplate, navigation fragments, repeated links, metadata-like text, and other |
| low-value lines. It is intended for use cases that need broad Japanese web text |
| with less page-structure noise than the original subset. |
|
|
| ## Dataset Creation |
|
|
| After applying `MK0727/corpus-refiner-jp`, documents were filtered out when the |
| refined text was 200 characters or shorter, or when it was 4096 tokens or longer |
| with `sbintuitions/modernbert-ja-130m`. |
