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".
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.
The table below shows the number of samples per category on DMath.
| ARI | COM | COR | POS | GEO | Total | |
|---|---|---|---|---|---|---|
| Train | 2,476 | 1,338 | 1,656 | 1,417 | 1,056 | 7,943 |
| Test | 669 | 334 | 402 | 383 | 291 | 2,079 |
| Total | 3,145 | 1,672 | 2,058 | 1,800 | 1,347 | 10,002 |

The figure below shows the accuracy comparison over various reasoning categories on DMath for RoBERTa (Liu et al., 2019), GPT-2 (Radford et al., 2019), ChatGPT (gpt-3.5-turbo; OpenAI) and GPT-4 (OpenAI, 2023). We use the fine-tuning approach for RoBERTa and GPT-2 and use the prompting approach for ChatGPT and GPT-4. The worst problem categories differ across MWP models.
The figure below shows the accuracy comparison results of MWP models on the DMath per expression forms in English. "NL prompt" means the natural language prompt. We set few-shot CoT (Wei et al., 2022) as NL prompt and PAL (Gao et al., 2022) as Python code prompt. We use RoBERTa (Liu et al., 2019) and CodeGPT (Lu et al., 2021) as the models for expression tree and Python code in the fine-tuning approach. We use GPT-4 (OpenAI, 2023) as the models for NL prompt and Python code prompt in the prompting approach. A specific prompt type is preferred depending on the problem.
We use gpt-3.5-turbo-0301 for ChatGPT and gpt-4-0314 for GPT-4.

abstract = "The math word problem (MWP) is a complex task that requires natural language understanding and logical reasoning to extract key knowledge from natural language narratives. Previous studies have provided various MWP datasets but lack diversity in problem types, lexical usage patterns, languages, and annotations for intermediate solutions. To address these limitations, we introduce a new MWP dataset, named DMath (Diverse Math Word Problems), offering a wide range of diversity in problem types, lexical usage patterns, languages, and intermediate solutions. The problems are available in English and Korean and include an expression tree and Python code as intermediate solutions. Through extensive experiments, we demonstrate that the DMath dataset provides a new opportunity to evaluate the capability of large language models, i.e., GPT-4 only achieves about 75{\%} accuracy on the DMath dataset.",
