# Manalyzer: End-to-end Automated Meta-analysis with Multi-agent System

[**Project Page**](https://black-yt.github.io/meta-analysis-page/) | [**Paper**](https://huggingface.co/papers/2505.20310) | [**GitHub**](https://github.com/black-yt/Manalyzer)

## Overview

Meta-analysis is a systematic research methodology that synthesizes data from multiple existing studies to derive comprehensive conclusions. Traditional meta-analysis involves a complex multi-stage pipeline including literature retrieval, paper screening, and data extraction, which demands substantial human effort and time.

**Manalyzer** is a multi-agent system that achieves end-to-end automated meta-analysis through tool calls. This repository contains the benchmark constructed to evaluate meta-analysis performance, comprising 729 papers across 3 domains (Atmosphere, Agriculture, and Environment), encompassing text, image, and table modalities, with over 10,000 data points.

## Dataset Structure

The benchmark consists of 729 papers across 3 scientific domains:
- **Atmosphere**: 1,196 examples
- **Agriculture**: 4,336 examples
- **Environment**: 1,125 examples

### Data Fields

Each example in the dataset contains:
- `field`: The scientific domain (Atmosphere, Agriculture, or Environment).
- `paper_idx`: Unique index of the source paper.
- `doi`: Digital Object Identifier of the source paper.
- `type`: Category of the data point.
- `table_or_image`: Visual modality (extracted image of a table or figure).
- `text_or_caption`: Associated text or caption providing context for the visual content.
