BAAI/CCI-Data

Data Description

With the rapid development of large language models, the demand for high-quality datasets in both the industry and academia is growing. These datasets not only need to contain a vast amount of information but also require rigorous screening and cleaning to ensure their accuracy and the safety of downstream models and applications. However, the currently popular public datasets in the industry have certain quality and security risks, especially in the Chinese domain where high-quality datasets are particularly lacking. Moreover, constructing a safe Chinese dataset also faces many challenges. Therefore, building a dataset that has undergone strict screening and standardized processing is particularly important for the innovation and development of LLMs.

Our CCI (Chinese Corpora Internet) dataset consists of high-quality, trustworthy sources from internet sites within mainland China. It has undergone rigorous data cleaning and deduplication, with targeted detection and filtering in aspects of content quality. The rules for data processing include:

• Rule-based filtering: density-based extraction, keyword filtering, spam information filtering, conversion between simplified and traditional Chinese, etc.
• Model-based filtering: filtering of low-quality content by training a classification model
• Deduplication: within and between datasets dedup

Additionally, in response to the issue of pre-training data being large in scale and prone to causing leaks of evaluation data, we specifically conduct rigorous screening and filtering of several current mainstream Chinese evaluation datasets during the data processing phase.

The CCI corpus released (CCI v1.0.0) is 104GB in size. The overall timespan of the dataset ranges from January 2001 to November 2023.

Update

• November 29, 2023, CCI v1.0.0 released!
