+# RAVine-mapper
 
+This repository contains the URL-to-document ID mapping files (`RAVine-mapper`), which are crucial for the implementation of the `fetch` tool within the [RAVine: Reality-Aligned Evaluation for Agentic Search](https://arxiv.org/abs/2507.16725) framework. This dataset is essential when utilizing RAVine for agentic search evaluations.
 
+RAVine (Reality-Aligned eValuation framework for agentic LLMs with search) is a comprehensive evaluation system designed for agentic search. It encompasses a web environment, benchmark datasets, and a novel evaluation method, providing a full-process, reproducible, and goal-aligned evaluation sandbox for agentic LLMs with search capabilities.
