Web-based RAG evaluation
Effortless Web-Based RAG Evaluation Using Tavily and LangGraph
Introduction
Every data science enthusiast knows that a vital first step to building a successful model or algorithm is having a reliable evaluation set to aspire to. In the rapidly evolving landscape of Retrieval-Augmented Generation (RAG) and AI-driven search systems, the importance of high-quality eval datasets is crucial.
In this article, we introduce an agentic workflow designed to generate subject-specific dynamic evaluation datasets, enabling precise validation of web search augmented agents’ performance.
Known RAG evaluation datasets, such as HotPotQA, CRAG, and MultiHop-RAG, have been pivotal in benchmarking and fine-tuning models. However, these datasets primarily focus on evaluating performance with static, pre-defined document sets. As a result, they fall short when it comes to evaluating web-based RAG systems, where data is dynamic, contextual, and ever-changing.
This gap presents a significant challenge: how do we effectively test and refine RAG systems designed for real-world web search scenarios? Enter the Real-Time Dataset Generator for RAG Evals — an agentic tool leveraging Tavily’s Search Layer and the LangGraph framework to create diverse, relevant, and dynamic datasets tailored specifically for web based RAG agents.
How does it work?
The Real-Time Dataset Generator follows a systematic workflow to create high-quality evaluation datasets:
Input
The workflow begins with user-provided inputs.
Domain-Specific Search Query Generation
If a subject is provided (e.g., “NBA Basketball”), the system generates a set of search queries. This ensures queries are tailored to gather high-quality, recent, and subject-specific information.
Web Search with Tavily
This step guarantees that the dataset reflects current and relevant information, particularly for web search RAG evaluation, where up-to-date data is crucial.This is the heart of the RAG Dataset Generator, transforming queries into actionable, high-quality data that forms the foundation of the evaluation set.
Q&A Pair Generation
For each website returned by Tavily, the system generates question-answer pair using a map-reduce paradigm to ensure efficient processing across multiple sources. This step is implemented using LangGraph’s Send API.
Saving the Evaluation Set
Finally, the generated dataset is saved either locally or to Langsmith, based on the input configuration.
Output
The result is a well-structured, subject-specific evaluation dataset, ready for use in advanced evaluation methods like LLM-as-a-Judge.
