# Dataset Card for "Calc-ape210k"


## Summary

This dataset is an instance of Ape210K dataset, converted to a simple HTML-like language that can be easily parsed (e.g. by BeautifulSoup). The data contains 3 types of tags:
- gadget: A tag whose content is intended to be evaluated by calling an external tool (sympy-based calculator in this case)
- output: An output of the external tool
- result: The final answer of the mathematical problem (a number)


## Supported Tasks

The dataset is intended for training Chain-of-Thought reasoning **models able to use external tools** to enhance the factuality of their responses.
This dataset presents in-context scenarios where models can outsource the computations in the reasoning chain to a calculator.


## Construction Process

First, we translated the questions into English using Google Translate. Next, we parsed the equations and the results. We linearized
the equations into a sequence of elementary steps and evaluated them using a sympy-based calculator. We numerically compare the output
with the result in the data and remove all examples where they do not match (less than 3% loss in each split). Finally, we save the
chain of steps in the HTML-like language in the `chain` column. We keep the original columns in the dataset for convenience. We also perform
in-dataset and cross-dataset data-leak detection within [Calc-X collection](https://huggingface.co/collections/MU-NLPC/calc-x-652fee9a6b838fd820055483).
Specifically for Ape210k, we removed parts of the validation and test split, with around 1700 remaining in each.

You can read more information about this process in our [Calc-X paper](https://arxiv.org/abs/2305.15017).


## Content and Data splits

The default config contains filtered splits with data leaks removed.
You can load it using:

```python3
datasets.load_dataset("MU-NLPC/calc-ape210k")
```

In the `original-splits` config, the data splits are unfiltered and correspond to the original Ape210K dataset. See [ape210k dataset github](https://github.com/Chenny0808/ape210k) and [the paper](https://arxiv.org/abs/2009.11506) for more info.
You can load it using:

```python3
datasets.load_dataset("MU-NLPC/calc-ape210k", "original-splits")
```


Columns:
- `id` - id of the example
- `question` - the description of the math problem. Automatically translated from the `question_chinese` column into English using Google Translate
- `question_chinese` - description of the math problem in Chinese
- `chain` - linearized `equation`, sequence of arithmetic steps in HTML-like language that can be evaluated using our sympy-based calculator
- `result` - result as a string (can be an integer, float, or a fraction)
- `result_float` - result as a float
- `equation` - a nested expression that evaluates to the correct answer

Columns `id`, `question`, `chain`, and `result` are present in all datasets in [Calc-X collection](https://huggingface.co/collections/MU-NLPC/calc-x-652fee9a6b838fd820055483).
