# PuMVR: Punjabi Multimodal Visual Reasoning Benchmark

## 🌟 Dataset Overview

**PuMVR (Punjabi Multimodal Visual Reasoning)** is a novel benchmark designed to evaluate **script-dependent performance biases** in Vision-Language Models (VLMs). It addresses the critical gap that current VLM evaluations fail to test whether models are truly **multi-script**, a distinction vital for languages like Punjabi which are actively written in multiple scripts.

The dataset features **375 unique image-text reasoning tasks** focused on Punjabi culture, history, and daily life. All instances are translated and rigorously validated across the three active Punjabi writing systems: **Gurmukhi (pa-Guru), Shahmukhi (pa-Arab), and Roman (pa-Latn)**.

* **Total Instances:** 375
* **Total Size:** 541 MB
* **Language:** Punjabi (pa) with three distinct script variants.
* **Target Models:** State-of-the-art VLMs

## 📊 Dataset Structure and Statistics

The dataset is organized into a single split (`train`) and is composed of image data and corresponding textual annotations stored in a JSON file.

### Data Fields

The dataset schema contains all necessary components for running multiple-choice VQA across three scripts:

| Field Name | Data Type | Description |
| :--- | :--- | :--- |
| **`id`** | `string` | Unique identifier (e.g., `C1_001`). |
| **`category`** | `string` | The specific task category (1 of 6). |
| **`image`** | `Image` | The associated visual input (decoded from the file path). |
| **`reasoning`** | `string` | Human-written explanation for the ground truth answer (in English). |
| **`scripts_[script]_question`** | `string` | The reasoning question in the specified script. |
| **`scripts_[script]_options`** | `list[string]`| 4 multiple-choice options in the specified script. |
| **`scripts_[script]_answer`** | `string` | The single correct option in the specified script. |

*(The `[script]` placeholder is one of: `gurmukhi`, `shahmukhi`, or `roman`.)*

### Task Categories

The 375 instances are distributed across 6 categories, ensuring a comprehensive test of multimodal script robustness:

1.  **Visual Analogies:** Tests relational reasoning (e.g., Turban:Head :: Shoe:?).
2.  **Cultural Object Recognition:** Tests knowledge of Punjabi-specific cultural items (e.g., *Phulkari*, musical instruments).
3.  **Festival & Celebration Reasoning:** Tests cultural knowledge and temporal reasoning around regional events (e.g., *Lohri*).
4.  **Architectural & Landmark Recognition:** Tests visual and geographic grounding of regional landmarks (e.g., Golden Temple).
5.  **Text-in-Image Reasoning:** Tests cross-script OCR and multimodal comprehension, including scenarios where image text and question text scripts are mismatched.
6.  **Abstract Visual-Linguistic Reasoning:** Tests basic spatial and logical reasoning with Punjabi language labels.

## ⚖️ Ethical and Legal Considerations

### Licenses
* **Data:** The PuMVR dataset is released under the **Creative Commons Attribution 4.0 International License (CC BY 4.0)**.
* **Images:** Majority (approximately 95%) of the images are AI-generated (synthetic data) to ensure cultural specificity and clear licensing. The remaining images are sourced from public domain, Wikimedia Commons, and original photography. 

### Data Creation and Validation
The textual data was created and rigorously validated by a team of native speakers across both Indian and Pakistani Punjabi contexts to ensure **semantic equivalence** and **cultural appropriateness** across the Gurmukhi, Shahmukhi, and Roman scripts.

### Limitations
The dataset is highly focused on **Punjabi culture**, which introduces a domain-specific bias. The Romanization used reflects common digital usage but is not strictly standardized, mirroring real-world multi-script challenges.
