Additional evaluation techniques

Ragas is just one of many evaluation tools and techniques available to evaluate your RAG system. This is not an exhaustive list, but in the following subsections, we will discuss some of the more popular techniques you can use to evaluate the performance of your RAG system, once you have obtained or generated ground-truth data.

Bilingual Evaluation Understudy (BLEU)

BLEU measures the overlap of n-grams between the generated response and the ground-truth response. It provides a score indicating the similarity between the two. In the context of RAG, BLEU can be used to evaluate the quality of the generated answers by comparing them to the ground-truth answers. By calculating the n-gram overlap, BLEU assesses how closely the generated answers match the reference answers in terms of word choice and phrasing. However, it’s important to note that BLEU is more focused on surface-level similarity and may not capture the semantic meaning or relevance...
