## Dataset Description
This dataset was compiled from code repositories hosted on [Gitee](https://gitee.com), China's largest code hosting platform and a leading alternative to GitHub in the Chinese developer community. Gitee is widely used by Chinese developers, enterprises, and open-source projects, making this dataset particularly valuable for training code models with strong Chinese language understanding and Chinese coding conventions.
### Dataset Summary

| **File Format** | Parquet with Zstd compression (468 files) |
### Key Features
- **Large-scale Chinese code corpus**: Contains code from over 3 million repositories, many featuring Chinese comments, documentation, and variable names
- **Diverse language coverage**: Spans 554 programming languages identified by [go-enry](https://github.com/go-enry/go-enry) (based on GitHub Linguist rules)

```
## Dataset Creation
### Pipeline Overview
The dataset was created through a multi-stage pipeline:
1. **Repository Discovery**
2. **Branch Selection**: Selecting the main branch for each repository (priority: `master` > `main` > `develop` > `dev` > first branch)
3. **Repository Downloading**
4. **Content Extraction**: Extracting and filtering source code files
5. **Parquet Generation**: Writing filtered records to Parquet shards with Zstd compression
### Language Detection
Programming languages are detected using [go-enry](https://github.com/go-enry/go-enry), a Go port of GitHub's Linguist library. Only files classified as **Programming** or **Markup** language types are included (Data and Prose types are excluded).
### License Detection
Licenses are detected by:
1. Scanning for license files (`LICENSE`, `LICENSE.txt`, `LICENSE.md`, `COPYING`, etc.)
2. Matching license text against known patterns (MIT, Apache 2.0, GPL variants, BSD, Creative Commons, etc.)
3. Defaulting to "unknown" if no license can be detected
**Blocked Licenses**: The following restrictive licenses are excluded from the dataset:
- `cc-by-nd`, `cc-by-nd-2.0`, `cc-by-nd-3.0`, `cc-by-nd-4.0` (Creative Commons No-Derivatives)
- `commons-clause`
- `sspl`, `sspl-1.0` (Server Side Public License)
### File Filtering
Extensive filtering is applied to ensure data quality:

- `generated by`, `do not edit`, `auto-generated`, `autogenerated`, `automatically generated`, `code generator`, `generated code`, `this file is generated`, `@generated`, `<auto-generated`
- **Empty Files**: Files that are empty or contain only whitespace are excluded
- **Long Lines**: Files with any line exceeding 1,000 characters are excluded
- **go-enry Filters**: Additional filtering using go-enry's `IsVendor()`, `IsImage()`, `IsDotFile()`, `IsTest()`, and `IsGenerated()` functions
- **Documentation-only Repos**: Repositories containing only documentation files (no actual code) are skipped
### Source Data

## Considerations for Using the Data
### Personal and Sensitive Information
The dataset may contain:
- Email addresses in code comments or configuration files
