# Traditional Chinese C4

### Dataset Summary

Data obtained from 2025-18 and 2025-13  Common Crawl. 


Downloaded and processed using [code](https://github.com/jedcheng/c4-dataset-script) based on another [project](https://github.com/shjwudp/c4-dataset-script) attempting to recreate the C4 dataset.


The resultant dataset contains both simplified and traditional Chinese. 
It was then filtered using a [modified list](https://github.com/jedcheng/c4-dataset-script/blob/master/SC_filter/SC_list.txt) of simplified Chinese characters to obtain [another traditional Chinese dataset](https://huggingface.co/datasets/jed351/Traditional-Chinese-Common-Crawl-Filtered).


I am still ironning out the process of filtering.
The 2025-13 dataset was deduplicated without splitting into shards resulting in a smaller dataset than the 2025-18 dataset.

Unfortunately, this process takes 2 CPU nodes for 4 hours. 
In addition, other people would have done a better job at cleaning the common crawl.

To preserver time, money and resources, I will not work on this dataset anymore but instead shift my focus to the [Traditional Chinese Common Crawl dataset](https://huggingface.co/datasets/jed351/Traditional-Chinese-Common-Crawl).
