## Scoring with Multiple Aspects 



![Multiple Aspects](https://allenai.github.io/re-align/images/eval_2.png)

### Helpfulness, Clarity, Factuality, Depth, and Engagement
 
`score_multi` is for evaluating the first 800 examples on Helpfulness, Clarity, Factuality, Depth, and Engagement.

```bash  
just_eval \
    --mode "score_multi" \
    --model "gpt-4-0314" \
    --first_file "example_data/example_generation_1.json" \
    --output_file "example_data/eval_outputs/1.score_multi.gpt-4.json"

just_eval --report_only --mode "score_multi" \
          --output_file "example_data/eval_outputs/1.score_multi.gpt-4.json" 

cat example_data/eval_outputs/1.score_multi.gpt-4.eval_res.json 
```


### Safety

`score_safety` is for evaluating the last 200 examples on Safety.

```bash    
just_eval \
    --mode "score_safety" \
    --model "gpt-3.5-turbo-0613" \
    --first_file "example_data/example_generation_safety.json" \
    --output_file "example_data/eval_outputs/1.safety.score_safety.chatgpt.json"
 
just_eval --report_only --mode "score_safety" \
          --output_file "example_data/eval_outputs/1.safety.score_safety.chatgpt.json" 

cat example_data/eval_outputs/1.safety.score_safety.chatgpt.eval_res.json         
```
