# CRAG Dataset Documentation

## Dataset Version Information

- **DATASET_DESCRIPTION_VERSION**: `v3`
- **DATASET_VERSION**: `v3`

## Overview

The CRAG dataset is designed to support the development and evaluation of Retrieval-Augmented Generation (RAG) models. It consists of two main types of data:

1. **Question Answering Pairs:** Pairs of questions and their corresponding answers.
2. **Retrieval Contents:** Contents for information retrieval to support answer generation.

Retrieval contents are divided into two types to simulate practical scenarios for RAG:

1. **Web Search Results:** For each question, up to `50` **full HTML pages** are stored, retrieved using the question text as a search query. For Task 1, `5 pages` are **randomly selected** from the `top-10 pages`. These pages are likely relevant to the question, but relevance is not guaranteed.
2. **Mock KGs and APIs:** The Mock API is designed to mimic real-world **Knowledge Graphs (KGs)** or **API searches**. Given some input parameters, they output relevant results, which may or may not be helpful in answering the user's question.
