# WAON-Bench: Japanese Cultural Image Classification Dataset
|
| 28 |
+
WAON-Bench is a small-scale, manually curated image classification dataset designed to benchmark Vision-Language models on the visual understanding of Japanese culture.
|
| 29 |
+
It consists of 385 images, each corresponding to a distinct class, capturing a wide range of cultural, natural, and everyday elements of Japanese life.
|
| 30 |
|
| 31 |
|
| 32 |
+
## Data Collection Pipeline
|
| 33 |
+
We followed the pipeline below to construct the dataset:
|
| 34 |
+
|
| 35 |
+
1. **Class Definition**: A total of 385 class names were manually defined and grouped into eight top-level categories:
|
| 36 |
+
animal, building, event, everyday, food, nature, scenery, and tradition.
|
| 37 |
+
2. **Image Selection**: For each class, a representative image was manually retrieved using Google Image Search. \
|
| 38 |
+
Images were selected based on the following criteria:
|
| 39 |
+
- The image should clearly represent the intended class.
|
| 40 |
+
- It should not contain elements that could be easily confused with other classes.
|
| 41 |
+
|
| 42 |
+
