Dataset Creation

Curation Rationale

The dataset was designed to advance AI systems that can automatically interpret retail price information and product details from Brazilian contexts. It supports OCR, data extraction, and intelligent retail automation.

Source Data

• Contributors: Images sourced from Brazilian supermarkets, retail stores, and e-commerce listings
• Collection Process: Price tags and product listings were captured in real-world retail environments and online platforms. Personal data or store identifiers were removed.

Other Known Limitations

• Bias: Overrepresentation of urban and national chain stores
• Image Quality: Varying resolution and lighting conditions may affect OCR performance
• Currency Consistency: Prices uniformly represented in BRL (Brazilian Real), though rounding and discount patterns vary by source

Intended Uses

✅ Direct Use

• Training AI for OCR and product information extraction
• Retail and pricing analytics
• Product catalog structuring for e-commerce applications
• Research in multilingual retail text processing
• Development of intelligent shelf-scanning or checkout systems

❌ Out-of-Scope Use

• Commercial reproduction of store or product information without consent
• Misuse of data for market manipulation or competitive intelligence
• Use of dataset for real-time surveillance in retail spaces
