Dataset Description

EMMA (Enhanced MultiModal reAsoning) is a benchmark targeting organic multimodal reasoning across mathematics, physics, chemistry, and coding. EMMA tasks demand advanced cross-modal reasoning that cannot be solved by thinking separately in each modality, offering an enhanced test suite for MLLMs' reasoning capabilities.

EMMA is composed of 2,788 problems, of which 1,796 are newly constructed, across four domains. Within each subject, we further provide fine-grained labels for each question based on the specific skills it measures.

Data Format

The dataset is provided in jsonl format and contains the following attributes:

{
    "pid": [string] Problem ID, e.g., “math_1”,
    "question": [string] The question text,
    "options": [list] Choice options for multiple-choice problems. For free-form problems, this could be a 'none' value,
    "answer": [string] The correct answer for the problem,
    "image_1": [image] ,
    "image_2": [image] ,
    "image_3": [image] ,
    "image_4": [image] ,
    "image_5": [image] ,
    "solution": [string] The detailed thinking steps required to solve the problem,
    "subject": [string] The subject of data, e.g., “Math”, “Physics”...,
    "task": [string] The task of the problem, e.g., “Code Choose Vis”,
    "category": [string] The category of the problem, e.g., “2D Transformation”,
    "source": [string] The original source dataset of the data, e.g., “math-vista”. For handmade data, this could be “Newly annotated” ,
    "type": [string] Types of questions, e.g., “Multiple Choice”, “Open-ended”,
    "context": [string] Background knowledge required for the question. For problems without context, this could be a 'none' value,
