🎃 Overview

The M²RAG benchmark evaluates Multi-modal Large Language Models (MLLMs) by using multi-modal retrieved documents to answer questions. It includes four tasks: image captioning, multi-modal QA, fact verification, and image reranking, assessing MLLMs’ ability to leverage knowledge from multi-modal contexts.

🎃 Data Storage Structure

The data storage structure of M2RAG is as follows：

M2RAG/
    ├──fact_verify/
    ├──image_cap/
    ├──image_rerank/
    ├──mmqa/
    ├──imgs.lineidx.new
    └──imgs.tsv

❗️Note: To obtain the imgs.tsv, you can follow the instructions in the WebQA project. Specifically, you need to first download all the data from the folder WebQA_imgs_7z_chunks, and then run the command 7z x imgs.7z.001to unzip and merge all chunks to get the imgs.tsv.
