## Dataset Creation
|
| 94 |
+
|
| 95 |
+
### Curation Rationale
|
| 96 |
+
|
| 97 |
+
Publicly available datasets for handwritten Ethiopic scripts are scarce, especially at character level. This dataset was created to provide a **standardized, balanced, and lightweight benchmark** for Amharic handwritten character recognition, enabling both academic research and practical OCR system development under limited computational resources.
|
| 98 |
+
|
| 99 |
+
### Source Data
|
| 100 |
+
|
| 101 |
+
#### Data Collection and Processing
|
| 102 |
+
|
| 103 |
+
1. Handwritten characters were collected on paper forms
|
| 104 |
+
2. Pages were scanned or photographed
|
| 105 |
+
3. Individual characters were extracted and cropped
|
| 106 |
+
4. Images were converted to grayscale
|
| 107 |
+
5. Resized to a fixed resolution of 32×32 pixels
|
| 108 |
+
6. Manually organized into class-specific directories
|
| 109 |
+
|
| 110 |
+
No synthetic data generation was used.
|
| 111 |
+
|
| 112 |
+
#### Source Data Producers
|
| 113 |
+
|
| 114 |
+
The handwritten samples were produced by human contributors mainly in an academic native environment though a portion of participants are also tigrinya native. No personally identifiable information is associated with the samples.

## Annotations
|
| 119 |
+
|
| 120 |
+
### Annotation Process
|
| 121 |
+
|
| 122 |
+
Annotations are implicit and directory-based. Each image inherits its label from the directory name representing a specific Geʽez character class. This mapping serves as the ground-truth annotation.
|
| 123 |
+
|
| 124 |
+
### Annotators
|
| 125 |
+
|
| 126 |
+
Annotation and class assignment were performed by the dataset creator during dataset organization and validation.
|
| 127 |
+
|
| 128 |
+
### Personal and Sensitive Information
|
| 129 |
+
|
| 130 |
+
This dataset does **not** contain:
|
| 131 |
+
|
| 132 |
+
- Names or identifiers
|
| 133 |
+
- Demographic metadata
|
| 134 |
+
- Sensitive personal information
|
| 135 |
+
|
| 136 |
+
The dataset consists solely of isolated handwritten character images.

## Bias, Risks, and Limitations
|
| 141 |
+
|
| 142 |
+
| Consideration | Description |
|
| 143 |
+
|---------------|-------------|
|
| 144 |
+
| **Demographic bias** | Handwriting styles may reflect a limited demographic group due to localized data collection from less than 500 Dire Dawa Universty Students only |
|
| 145 |
+
| **Style coverage** | Extreme handwriting variations (e.g., elderly or non-academic writers) may be underrepresented |
|
| 146 |
+
| **Scope limitation** | Character-level only; does not capture word or sentence context and due to the 500 participants some unique paterns might not be collected |
|
| 147 |
+
|
| 148 |
+
### Recommendations
|
| 149 |
+
|
| 150 |
+
- Fine-tune models with additional local handwriting samples for deployment
|
| 151 |
+
- Combine this dataset with document-level segmentation pipelines when building full OCR systems
|
| 152 |
+
- Apply data augmentation to improve robustness to handwriting variability
