    2552. 

  2552. <p>当我们为某个真实线上系统开发了检索增强生成 (RAG) 应用，那么在此应用正式上线提供服务前，我们需要评估 RAG 的表现到底是怎样的。如果发现现有的 RAG 效果不够理想，可能需要一些新的 RAG 算法流程来改进。在这之前，就需要对 RAG 流程进行评估，得到评估指标，然后才能进行自动化对比，观察改进的流程是否真的有效。</p>

  2553. <h2 id="ragas">二、RAGAS评估框架<a class="headerlink" href="#ragas" title="Permanent link">¶</a></h2>
    2554. 

  2554. <p>RAGAS (Retrieval Augmented Generation Assessment) 我们一般称为 Automated Evaluation of Retrieval Augmented Generation，即检索增强生成的自动评估。Ragas是一个大模型评测框架，可以评估检索增强生成（RAG）的效果，帮助分析模型的输出，了解模型在给定任务上的表现。Github地址:  https://github.com/explodinggradients/ragas</p>
    2555. 

  2555. <p>RAGAS的评估主要基于两个方向：检索部分和生成部分，那么针对不同的部分评估的指标也会有所区分。接下来，我们将分别介绍RAGAS评估框架所需的数据，评估指标，实际用例等。</p>
    2556. 

  2556. <h3 id="1">1 数据说明<a class="headerlink" href="#1" title="Permanent link">¶</a></h3>
    2557. 

  2557. <p>最开始的 RAGAs 在评估数据集时，不必依赖人工标注的标准答案，而是通过底层的大语言模型 (LLM) 来进行评估。所以只需要一个带有问题-答案对的评估数据集（QA 对），如：https://huggingface.co/datasets/m-ric/huggingface_doc

    2562. 

  2562. <li>contexts：从用于回答question外部知识源中检索的上下文。</li>
