| 4. **Aspect Critiques**: Designed to judge the submission against defined aspects like harmlessness, correctness, etc. You can also define your own aspect and validate the submission against your desired aspect. The output of aspect critiques is always binary. | ||

| Through repeated experiments, we have found that the quality of a RAG pipeline is highly dependent on these two dimensions. The final `ragas_score` is the harmonic mean of these two factors. | ||
| The final `ragas_score` is the harmonic mean of of individual metric scores. |

is the harmonic mean still relavent?

This is specified in the docs.

MetricWithLLM doesnot have a post init

why are we doing this?
also comment that there so that it is easier for the next person reading it

if you get the time could you finish the doc string like we have for context relevancy?
or I can do it too
| if isinstance(context, list): | ||
| context = "\n".join(context) | ||
| question = f"{question } answer using context: {context}" |

why is the type for context t.Optional[str] and we are checking if it is a list here?

Context is converted to list here before this function.

What
Added support for Aspect critiques
Why
Many aspects can be judged on a binary basis two ensure quality like harmlessness, correctness, etc are now possible with ragas. Users also can define their aspects for evaluation.
How
Added a simple CoT + Self-consistency step algorithm
Testing
Added
harmlessnessmetrics to tests and ran some exercises to ensure quality.
