## Supported Tasks

- **Task Categories**:
- Image Classification
- Text Recognition (OCR)
- Scene Understanding

- **Supported Tasks**:
- Korean text detection and transcription from travel-related signs
- Translation benchmarking for multilingual (Korean-English-Chinese-Japanese) tourism boards
- Scene text recognition in outdoor environments
- Visual understanding of travel information design and layout
- AI modeling for navigation and smart tourism applications

## Languages

- **Primary Language**: Korean
- **Secondary Presence**: English, Chinese, and Japanese (on multilingual tourism boards)

## Dataset Creation

### Curation Rationale
This dataset was developed to enable AI systems to interpret public travel-related signage and boards in Korea. It aids in building models for multilingual OCR, contextual translation, and navigation assistance for travelers, enhancing accessibility and smart tourism solutions.

### Source Data
- **Contributors**: Field photographers, tourism content collectors, and public dataset contributors
- **Collection Process**: Images were captured from public travel boards across airports, railway stations, tourist attractions, city centers, and cultural heritage sites. All identifiable personal information was removed before inclusion.

### Other Known Limitations
- **Bias**: Urban and major tourist destinations may be overrepresented
- **Environmental Variability**: Lighting conditions, reflections, or obstructions may affect image clarity
- **Context Limitations**: Does not include dynamic or digital displays (e.g., airport flight info screens)

## Intended Uses

### ✅ Direct Use
- OCR and multilingual text translation research for travel signs
- Training computer vision models for wayfinding and navigation
- Cross-lingual accessibility and tourism information apps
- Visual design research in public signage and information systems

### ❌ Out-of-Scope Use
- Commercial replication of signage designs without permission
- Geolocation inference or tracking of specific sites or individuals
- Misuse of public board content for unrelated commercial advertising
