StackMathQA is a meticulously curated collection of **2 million** mathematical questions and answers, sourced from various Stack Exchange sites. This repository is designed to serve as a comprehensive resource for researchers, educators, and enthusiasts in the field of mathematics and AI research. ## Configs ```YAML configs: - config_name: stackmathqa1600k data_files: data/stackmathqa1600k/all.jsonl default: true - config_name: stackmathqa800k data_files: data/stackmathqa800k/all.jsonl - config_name: stackmathqa400k data_files: data/stackmathqa400k/all.jsonl - config_name: stackmathqa200k data_files: data/stackmathqa200k/all.jsonl - config_name: stackmathqa100k data_files: data/stackmathqa100k/all.jsonl - config_name: stackmathqafull-1q1a data_files: preprocessed/stackexchange-math--1q1a/*.jsonl - config_name: stackmathqafull-qalist data_files: preprocessed/stackexchange-math/*.jsonl ``` How to load data: ```python from datasets import load_dataset ds = load_dataset("math-ai/StackMathQA", "stackmathqa1600k") # or any valid config_name ``` ## Preprocessed Data In the `./preprocessed/stackexchange-math` directory and `./preprocessed/stackexchange-math--1q1a` directory, you will find the data structured in two formats: 1. **Question and List of Answers Format**: Each entry is structured as {"Q": "question", "A_List": ["answer1", "answer2", ...]}. - `math.stackexchange.com.jsonl`: 827,439 lines - `mathoverflow.net.jsonl`: 90,645 lines - `stats.stackexchange.com.jsonl`: 103,024 lines - `physics.stackexchange.com.jsonl`: 117,318 lines - In total: **1,138,426** questions ```YAML dataset_info: features: - name: Q dtype: string description: "The mathematical question in LaTeX encoded format." - name: A_list dtype: sequence description: "The list of answers to the mathematical question, also in LaTeX encoded." - name: meta dtype: dict description: "A collection of metadata for each question and its corresponding answer list." ``` 2. **Question and Single Answer Format**: Each line contains a question and one corresponding answer, structured as {"Q": "question", "A": "answer"}. Multiple answers for the same question are separated into different lines. - `math.stackexchange.com.jsonl`: 1,407,739 lines - `mathoverflow.net.jsonl`: 166,592 lines - `stats.stackexchange.com.jsonl`: 156,143 lines - `physics.stackexchange.com.jsonl`: 226,532 lines - In total: **1,957,006** answers ```YAML dataset_info: features: - name: Q dtype: string description: "The mathematical question in LaTeX encoded format." - name: A dtype: string description: "The answer to the mathematical question, also in LaTeX encoded." - name: meta dtype: dict description: "A collection of metadata for each question-answer pair." ``` ## Selected Data The dataset has been carefully curated using importance resampling. We offer selected subsets of the dataset (`./preprocessed/stackexchange-math--1q1a`) with different sizes to cater to varied needs: ```YAML dataset_info: features: - name: Q dtype: string description: "The mathematical question in LaTeX encoded format." - name: A dtype: string description: "The answer to the mathematical question, also in LaTeX encoded." - name: meta dtype: dict description: "A collection of metadata for each question-answer pair." ``` ### StackMathQA1600K - Location: `./data/stackmathqa1600k` - Contents: - `all.jsonl`: Containing 1.6 million entries. - `meta.json`: Metadata and additional information. ```bash Source: Stack Exchange (Math), Count: 1244887 Source: MathOverflow, Count: 110041 Source: Stack Exchange (Stats), Count: 99878 Source: Stack Exchange (Physics), Count: 145194 ``` Similar structures are available for StackMathQA800K, StackMathQA400K, StackMathQA200K, and StackMathQA100K subsets. ### StackMathQA800K - Location: `./data/stackmathqa800k` - Contents: - `all.jsonl`: Containing 800k entries. - `meta.json`: Metadata and additional information. ```bash Source: Stack Exchange (Math), Count: 738850 Source: MathOverflow, Count: 24276 Source: Stack Exchange (Stats), Count: 15046 Source: Stack Exchange (Physics), Count: 21828 ``` ### StackMathQA400K - Location: `./data/stackmathqa400k` - Contents: - `all.jsonl`: Containing 400k entries. - `meta.json`: Metadata and additional information. ```bash Source: Stack Exchange (Math), Count: 392940 Source: MathOverflow, Count: 3963 Source: Stack Exchange (Stats), Count: 1637 Source: Stack Exchange (Physics), Count: 1460 ``` ### StackMathQA200K - Location: `./data/stackmathqa200k` - Contents: - `all.jsonl`: Containing 200k entries. - `meta.json`: Metadata and additional information. ```bash Source: Stack Exchange (Math), Count: 197792 Source: MathOverflow, Count: 1367 Source: Stack Exchange (Stats), Count: 423 Source: Stack Exchange (Physics), Count: 418 ``` ### StackMathQA100K - Location: `./data/stackmathqa100k` - Contents: - `all.jsonl`: Containing 100k entries. - `meta.json`: Metadata and additional information. ```bash Source: Stack Exchange (Math), Count: 99013 Source: MathOverflow, Count: 626 Source: Stack Exchange (Stats), Count: 182 Source: Stack Exchange (Physics), Count: 179 ``` ## Citation If you use StackMathQA in your research, please cite our technical report.
