Evaluation is the key to building robust Retrieval-Augmented Generation (RAG) systems. Leveraging Dria’s Persona Pipeline alongside custom workflows, this approach offers a comprehensive method to assess AI agents using context-specific data and diverse personas.

The Process

This workflow demonstrates how to evaluate your RAG pipeline by combining persona-driven question generation, contextual data scraping, and performance evaluation across multiple models. Here’s how it works:

  1. Generate Personas with Dria’s Persona Pipeline: Start by creating detailed personas tailored to your evaluation needs. These personas define the tone, focus, and perspective of the questions to be generated.
  2. Scrape Contextual Data: Use tools like Firecrawl to scrape relevant content from specific URLs or entire domains. This data serves as the foundation for generating nuanced, contextually rich questions.
  3. Generate Questions: Combine the generated personas with the scraped context to create targeted and diverse questions. These questions are crafted to evaluate the RAG pipeline’s ability to retrieve and reason effectively.
  4. Generate Answers: Use AI models to produce answers for the generated questions. These responses simulate real-world scenarios, offering insights into the performance of different RAG configurations.
  5. Evaluate Performance: Assess the generated answers using Promptfoo across multiple RAG configurations:
    • Simple RAG
    • RAG with Jina Reranker
    • RAG with Cohere Reranker

Why It Matters

This approach ensures a robust evaluation by testing multiple dimensions of your RAG system: • Contextual Relevance: Ensures the system retrieves and generates accurate, context-aware responses. • Model Comparison: Highlights strengths and weaknesses across different RAG configurations. • Scalable Evaluation: Allows for iterative testing and refinement at scale.
