# HumaniBench-MCQ: Task 3 (Multiple-Choice VQA) in MMMU Format

</p>

This dataset is a **format conversion** of Task 3 (`task3_Multiple_Choice_VQA`) from [HumaniBench](https://huggingface.co/datasets/vector-institute/HumaniBench), restructured to match the [MMMU](https://huggingface.co/datasets/MMMU/MMMU) schema so it can be used directly with MMMU-style evaluation pipelines.

**No questions, images, or answers were added, removed, or changed.** Only the column layout and answer format differ from the original.

## How to Load

```python
from datasets import load_dataset

ds = load_dataset("vector-institute/HumaniBench-MCQ", split="test")
```

---

## Dataset Structure

1,844 multiple-choice questions, one image each, in a single `test` split.

| Column | Type | Description |
|---|---|---|
| `id` | string | MMMU-style ID: `test_<Attribute>_<n>`, numbered within each attribute (e.g., `test_Gender_1`) |
| `question` | string | Question text, prefixed with the `<image 1>` placeholder |
| `options` | string | String-formatted list of answer choices, without letter prefixes (e.g., `['Male', 'Female', 'Non-binary', 'Gender-neutral']`) |
| `explanation` | string | Reasoning supporting the answer (optional; not required for evaluation) |
| `image_1` | image | Embedded image data |
| `img_type` | string | Image type, always `['Photographs']` |
| `answer` | string | Single-letter answer (e.g., `B`) |
| `demographic` | string | HumaniBench attribute being tested (e.g., Gender, Age). Used as the categorical field for grouping results (takes the place of MMMU's `topic_difficulty`) |
| `question_type` | string | Always `multiple-choice` |
| `subfield` | string | Left empty |
| `original_id` | string | ID from the original HumaniBench Task 3, for traceability |

### Example

```
id:               test_Gender_2
question:         <image 1> What gender representation is depicted by the statue of Lady Justice?
options:          ['Male', 'Female', 'Non-binary', 'Gender-neutral']
answer:           B
demographic:      Gender
question_type:    multiple-choice
original_id:      c6caaf72e5
```

---

### Differences from MMMU

- Only `image_1` is included, since every question uses a single image. MMMU's `image_2` to `image_7` columns are omitted.
- MMMU's `topic_difficulty` column is replaced by `demographic`, which holds the attribute being tested.
- `original_id` is an extra column not present in MMMU.

---

## Intended Use

- Evaluating multimodal models on human-centric multiple-choice VQA using MMMU-compatible evaluation code
- Comparing model accuracy across social attributes via `demographic`

For the full benchmark (7 tasks, 32,000+ image–question pairs), see the [original HumaniBench dataset](https://huggingface.co/datasets/vector-institute/HumaniBench).
