# Chinese Documents Dataset (PDF)
*This dataset consists of a curated collection of Chinese-language documents in PDF format. It includes textbooks, research papers, articles, public-domain books, and official documents written in Simplified and Traditional Chinese. The dataset supports AI research in OCR, document understanding, and multilingual text extraction.*

## Supported Tasks
- **Task Categories**:
- Document Classification
- OCR and Text Recognition
- Layout and Structure Analysis
- Language Modeling for Chinese
- **Supported Tasks**:
- Extraction of Chinese text from PDF documents
- Classification by topic (academic, legal, educational, literary)
- OCR for Simplified and Traditional Chinese scripts
- Benchmarking AI models for Chinese-language document parsing
## Languages
- **Primary Language**: Chinese (Simplified and Traditional)
- **Secondary Presence**: English, numbers, and technical symbols (common in bilingual or academic PDFs)
## Dataset Creation
### Curation Rationale
The dataset was curated to accelerate the development of AI models that can process, recognize, and understand Chinese-language PDFs with complex layouts and mixed scripts.
### Source Data
- **Contributors**: Open-access Chinese digital libraries, educational institutions, and volunteer data contributors.
- **Collection Process**: All PDFs were collected from legally available, open-licensed repositories and public-domain sources.
### Other Known Limitations
- **Bias**: Overrepresentation of educational and academic documents; fewer informal or handwritten materials
- **Format Variation**: Some PDFs contain scanned pages with varying print clarity
- **Script Variation**: Includes both Simplified (Mainland China) and Traditional (Taiwan, Hong Kong) content
## Intended Uses
### ✅ Direct Use
- Training OCR models for Simplified and Traditional Chinese
- Research on multilingual document understanding
- Digitization of Chinese educational and archival materials
### ❌ Out-of-Scope Use
- Identifying individuals from document data
- Commercial reuse of copyrighted materials
- Use in surveillance or profiling applications
