 ## Content and Data splits
 
-Content and splits 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.
+In the `original-splits` config, the data splits 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")
+```
+
+The default config contains filtered splits that remove in-dataset and cross-dataset data leaks within [Calc-X collection](https://huggingface.co/collections/MU-NLPC/calc-x-652fee9a6b838fd820055483). 
+In the case of Ape210k, we removed parts of the validation and test split, with around 1700 remaining in each. Refer to our paper for more details.

 Columns:
 - `id` - id of the example
-- `question` - the description of the math problem. Automatically translated from `question_chinese` column into English using Google Translate
+- `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 integer, float or a fraction)
+- `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).
