Supported Tasks
Task Categories:
- Image Classification
- Text Recognition (OCR)
- Document Understanding
Supported Tasks:
- Text extraction from Korean receipts (item names, prices, totals, dates)
- Receipt classification by store type or transaction type
- Multilingual OCR for bilingual receipts (Korean-English)
- Financial data parsing and analytics
- Research in automated expense tracking and accounting systems
Languages
- Primary Language: Korean
- Secondary Presence: English (on receipts from international or chain stores)
Dataset Creation
Curation Rationale
This dataset was created to help AI systems accurately extract structured financial information from receipts. It supports OCR, text parsing, and document understanding models in retail and finance applications.
Source Data
- Contributors: Field collection, simulated receipts, and crowdsourced images
- Collection Process: Receipts were photographed or scanned. All personal identifiers (names, addresses, payment info) were removed or anonymized before inclusion.
Other Known Limitations
- Bias: Urban and chain store receipts may dominate; small vendor receipts are less represented
- Image Quality Variability: Lighting, folds, or low-resolution printing may affect OCR accuracy
- Receipt Format Diversity: Variation in layouts, fonts, and lengths may pose challenges for text extraction
Intended Uses
✅ Direct Use
- Training OCR models for Korean receipts
- Document understanding and financial data extraction
- Automated expense tracking applications
- Academic research in computer vision and structured text parsing
❌ Out-of-Scope Use
- Reconstructing personal transaction history
- Commercial misuse of store or brand data without consent
- Using receipts for surveillance or tracking individuals
