# Oracle Bone Inscriptions Multi-modal Dataset (OBIMD) |
|
|
|
|
|
## Dataset Overview |
|
|
|
|
|
The Oracle Bone Inscriptions Multi-modal Dataset (OBIMD) is the first large-scale corpus providing pixel-aligned rubbings and facsimiles, character-level annotations, and sentence-level transcriptions and reading sequences for oracle bone inscription (OBI) research. This dataset enables multi-modal learning across visual, structural, and linguistic dimensions, laying the foundation for end-to-end OBI recognition and interpretation. |

## Dataset Statistics |
|
|
|
|
|
- Total OBI images: 10,077 across five Shang Dynasty phases |
|
|
- Annotated characters: 93,652 |
|
|
- Missing character positions: 21,667 (due to fragmentation) |
|
|
- Sentences: 21,941 syntactically validated |
|
|
- Non-sentential elements: 4,192 |
|
|
|
|
|
## Data Structure |
|
|
|
|
|
The dataset follows a three-level hierarchy: |
|
|
|
|
|
1. Image-level: Contains rubbing and facsimile pairs |
|
|
2. Sentence-level: Groups characters into meaningful units |
|
|
3. Character-level: Detailed annotations for each character |
|
|

## Data Modalities |
|
|
|
|
|
1. Rubbing images: Original scanned images of oracle bones |
|
|
2. Facsimile images: Expert reconstructions aligned with rubbings |
|
|
3. Character annotations: Bounding boxes and classifications |
|
|
4. Sentence groupings: Semantic organization of characters |
|
|
5. Reading sequences: Order of characters within sentences |
|
|
 |
|
|
|
|
|
## Hierarchical Character Metadata Supplement |
|
|
|
|
|
This folder contains supporting materials for the character hierarchy used in OBIMD. It includes: |
|
|
|
|
|
1. Sub-character Images: Images of sub-character variants, stored in a two-level folder structure. The top-level directory is named by the main character UID, and each subfolder is named by the corresponding sub-character UID. |
|
|
2. Sub-character to Transcription Mapping: Maps each sub-character UID to its modern Chinese transcription. |
|
|
3. Sub-character to Main-character Mapping: Maps each sub-character UID to its parent main character UID in the Oracular Digital Platform. |
|
|
|
|
|
## Usage Notes |
|
|
|
|
|
The dataset is designed to support various research tasks: |
|
|
|
|
|
- Character detection and recognition |
|
|
- Sentence-level character clustering |
|
|
- Character reordering within sentences |
|
|
- Multi-modal analysis (rubbing vs. facsimile) |
