Dataset Creation

Curation Rationale

This dataset was curated to support research on AI systems that process Russian-language documents, handle Cyrillic text layouts, and improve OCR and multilingual document understanding performance.

Source Data

• Contributors: Open-access Russian digital libraries, academic repositories, and public-domain archives.
• Collection Process: All PDFs were collected from open-license and publicly available repositories ensuring legal and ethical reuse.

Other Known Limitations

• Bias: Overrepresentation of formal and academic materials; fewer informal or regional texts
• Format Variation: Some PDFs contain scanned pages or multi-column layouts
• Language Scope: Focused on Standard Russian; limited inclusion of minority languages or dialects

Intended Uses

✅ Direct Use

• Training OCR and NLP models for Russian document understanding
• Research in Cyrillic-based text recognition and multilingual AI
• Digitization of Russian-language archives, literature, and educational resources

❌ Out-of-Scope Use

• Extraction of private or identifiable information from PDFs
• Commercial redistribution of copyrighted materials
• Use in profiling, surveillance, or handwriting recognition applications
