# InfoVQA


## Overview

InfoVQA (Infographic Visual Question Answering) is a benchmark designed to evaluate AI models' ability to answer questions based on information-dense images such as charts, graphs, diagrams, maps, and infographics. It focuses on understanding complex visual information presentations.

## Task Description

- **Task Type**: Infographic Question Answering
- **Input**: Infographic image + natural language question
- **Output**: Single word or phrase answer
- **Domains**: Data visualization, information graphics, visual reasoning

## Key Features

- Focuses on information-dense visual content
- Covers charts, graphs, diagrams, maps, and infographics
- Requires understanding visual layouts and data representations
- Tests information extraction and reasoning abilities
- Questions vary in complexity from direct lookup to inference

## Evaluation Notes

- Default evaluation uses the **validation** split
- Primary metric: **ANLS** (Average Normalized Levenshtein Similarity)
- Answers should be in format "ANSWER: [ANSWER]"
- Includes OCR text extraction as metadata for analysis
- Uses same dataset source as DocVQA (InfographicVQA subset)

## Prompt Template

**Prompt Template:**
```text
Answer the question according to the image using a single word or phrase.
{question}
The last line of your response should be of the form "ANSWER: [ANSWER]" (without quotes) where [ANSWER] is the answer to the question.
```

## Usage

### Using CLI

```bash
evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets infovqa \
    --limit 10  # Remove this line for formal evaluation
```

### Using Python

```python
from evalscope import run_task
from evalscope.config import TaskConfig

task_cfg = TaskConfig(
    model='YOUR_MODEL',
    api_url='OPENAI_API_COMPAT_URL',
    api_key='EMPTY_TOKEN',
    datasets=['infovqa'],
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
```
