Dataset Creation

Curation Rationale

This dataset was curated to help AI researchers and developers build and evaluate models capable of understanding Spanish-language PDFs, handling diverse fonts, layouts, and mixed multilingual text structures.

Source Data

• Contributors: Public Spanish-language repositories, educational archives, and open-access document sources.
• Collection Process: All PDFs were collected from open-license or public-domain sources to ensure legal and ethical reuse.

Other Known Limitations

• Bias: Predominantly Standard Spanish from Spain and Latin America; limited dialectal or informal text representation
• Format Variation: Includes both text-based and scanned PDF documents
• Content Scope: Focused mainly on formal and educational content

Intended Uses

✅ Direct Use

• Training and evaluation of OCR models for Spanish-language text
• Research in multilingual document understanding and digitization
• AI-powered document archiving and content classification

❌ Out-of-Scope Use

• Extracting or profiling individuals from document content
• Commercial redistribution of copyrighted materials
• Use in surveillance, handwriting identification, or behavioral analysis
