DMath (Diverse Math Word Problems)

This repository provides DMath (Diverse Math Word Problems), a collection of 10K high-quality grade school-level math word problems for the paper "It Ain’t Over: A Multi-aspect Diverse Math Word Problem Dataset".

Details of the dataset

DMath is a multi-aspect diverse MWP dataset, which has the following key features:

It fully covers problem types across five categories. These include arithmetic calculation (ARI), comparison (COM), correspondence (COR), geometry(GEO), and possibility (POS).
It consists of about 10,000 problems manually created by 43 human workers covering various lexical usage patterns on natural language narratives and expression trees.
It supports bilingual input languages, i.e., English and Korean.
It offers the annotation of expression trees and Python code as intermediate solutions.

In summary, DMath offers a wide range of diversity in problem types, lexical usage patterns, languages, and intermediate solution forms.
