StackMathQA

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 data science.

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

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

Selected Data

The dataset has been carefully curated using importance sampling. We offer selected subsets of the dataset (./preprocessed/stackexchange-math--1q1a) with different sizes to cater to varied needs:

StackMathQA1600K

• Location: ./data/stackmathqa1600k
• Contents:
  • all.jsonl: Containing 1.6 million entries.
  • meta.json: Metadata and additional information.

StackMathQA800K

• Location: ./data/stackmathqa800k
• Contents:
  • all.jsonl: Containing 800k entries.
  • meta.json: Metadata and additional information.

Similar structures are available for StackMathQA400K, StackMathQA200K, and StackMathQA100K subsets.
