# Filtered ABEJA-CC-JA
## Dataset Overview
This dataset is a filtered version of the large-scale Japanese pre-training corpus, [abeja-cc-ja](https://tech-blog.abeja.asia/entry/abeja-cc-ja-202409). It was created by duplicating the original dataset while excluding texts with a KenLM perplexity score. The goal is to extract high-quality Japanese text data to facilitate the training of language models.
## Data Structure
### Features
Each data entry contains the following attributes:
* **`url`**: The source URL of the scraped data.
* **`content`**: The extracted text body.
* **`perplexity`**: The weighted average perplexity score of the entire document, calculated using KenLM.
### Directory Structure
The dataset is provided in Parquet format and is organized in a directory structure as shown below:
```text
/data/commom_crawl_0/
├── common_crawl_0_filtered_0000.parquet
├── common_crawl_0_filtered_0001.parquet
└── ...
```
## Data Processing (Filtering)
The filtering process applies the following logic to the text data:
* **KenLM Model Used**: [lighttransport/japanese-scoring-model](https://huggingface.co/lighttransport/japanese-scoring-model)
* **Filtering Condition**: Retains texts with a perplexity score strictly below 40 and excludes those scoring 40 or higher.
