RAG Evaluation

Evaluate on CI/CD Pipeline

This evaluator detects the language of the input and output text to check for example if the generated answer is in the same language as the prompt,
or if it's in a specific expected language.

Off-Topic Detection

This metric evaluates whether all of the ground-truth relevant items present in the contexts are ranked higher or not. Higher scores indicate better precision.


__Docs:__ https://docs.ragas.io/en/latest/concepts/metrics/context_precision.html

Context Precision

This evaluator measures the extent to which the retrieved context aligns with the annotated answer, treated as the ground truth. Higher values indicate better performance.


__Docs:__ https://docs.ragas.io/en/latest/concepts/metrics/context_recall.html

Context Recall

This metric gauges the relevancy of the retrieved context, calculated based on both the question and contexts. The values fall within the range of (0, 1), with higher values indicating better relevancy.


__Docs:__ https://docs.ragas.io/en/latest/concepts/metrics/context_relevancy.html

Context Relevancy

This metric evaluates whether all of the output relevant items present in the contexts are ranked higher or not. Higher scores indicate better utilization.


__Docs:__ https://docs.ragas.io/en/latest/concepts/metrics/context_precision.html

Context Utilization

This evaluator assesses the extent to which the generated answer is consistent with the provided context. Higher scores indicate better faithfulness to the context, useful for detecting hallucinations.


__Docs:__ https://docs.ragas.io/en/latest/concepts/metrics/faithfulness.html

Faithfulness

This evaluator assesses the extent to which the generated answer is consistent with the provided context. Higher scores indicate better faithfulness to the context, useful for detecting hallucinations.

Haystack Faithfulness

Use an LLM as a judge with a custom prompt to do a true/false boolean evaluation of the message.

LLM Boolean Evaluator

Use an LLM as a judge with custom prompt to do a numeric score evaluation of the message.

LLM Score Evaluator

Allows you to check for simple text matches or regex evaluation.

LLM Basic Evaluator

Allows you to check for semantic similarity or dissimilarity between input and output and a
target value, so you can avoid sentences that you don't want to be present without having to
match on the exact text.


__Env vars:__ OPENAI_API_KEY, AZURE_API_KEY, AZURE_API_BASE

LLM Similarity Evaluator

This evaluator is a special version of Llama trained strictly
for acting as a guardrail, following customizable guidelines.
It can work both as a safety evaluator and as policy enforcement.
