# MaritimeBench

## Overview

MaritimeBench is a benchmark for evaluating AI models on maritime-related multiple-choice questions in Chinese. It consists of specialized questions related to maritime knowledge, navigation, marine engineering, and seafaring operations.

## Task Description

- **Task Type**: Maritime Knowledge Multiple-Choice QA (Chinese)
- **Input**: Maritime-related question with 4 answer choices (A-D)
- **Output**: Correct answer letter in brackets [A/B/C/D]
- **Language**: Chinese

## Key Features

- Specialized maritime domain questions
- Chinese language evaluation
- Multiple subsets covering different maritime topics
- Tests professional maritime knowledge
- Standardized Chinese exam format

## Evaluation Notes

- Default configuration uses **0-shot** evaluation
- Evaluates on test split
- Simple accuracy metric
- Answers extracted using regex for bracketed format [A/B/C/D]

## Usage

### Using CLI

```bash
evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets maritime_bench \
    --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=['maritime_bench'],
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
```
