# GEMBA

> 微软翻译团队出品的译文质量评估工具：用 GPT 按 MQM 错误体系（或直接打分）逐句给译文评分，加 --list_mqm_errors 可列出错误类型与严重程度，适合批量抽检译文。原文与译文需整理成行数一致的两个文本文件，需要 Python 与 OpenAI 或 Azure OpenAI 的 API Key（按量付费）；评分仅供参考，仍需译员复核。

# GEMBA-MQM and GEMBA-DA

## Setup

Install the package (Python >= 3.8):

```
pip install .
```

For editable installs during development:

```
pip install -e .
```

Set up secrets either for Azure API or OpenAI API: 

```
export OPENAI_AZURE_ENDPOINT=
export OPENAI_AZURE_KEY=
```

or

```
export OPENAI_API_KEY=
```

## Scoring with GEMBA

It assumes two files with the same number of lines. It prints the score for each line pair:

```
gemba --source=source.txt --hypothesis=hypothesis.txt --source_lang=English --target_lang=Czech --method="GEMBA-MQM" --model="gpt-4"
# or
python -m gemba --source=source.txt --hypothesis=hypothesis.txt --source_lang=English --target_lang=Czech --method="GEMBA-MQM" --model="gpt-4"
```

The main recommended methods: `GEMBA-MQM` and `GEMBA-DA` with the model `gpt-4`.

## Collecting and evaluating experiments for GEMBA-DA

Get mt-metric-eval and download resources:

```
git clone https://github.com/google-research/mt-metrics-eval.git
cd mt-metrics-eval
pip install .
alias mtme='python3 -m mt_metrics_eval.mtme'
mtme --download
cd ..
mv ~/.mt-metrics-eval/mt-metrics-eval-v2 mt-metrics-eval-v2
```

Collect data and run the scorer

```
python gemba_da.py 

export PYTHONPATH=mt-metrics-eval:$PYTHONPATH
python evaluate.py
```
