+# Dataset Card for Simple SQuAD
+
+<!-- Provide a quick summary of the dataset. -->
+This is a simplified version of SQuAD v1 dataset.
+
+## Dataset Details
+
+### Dataset Description
+
+<!-- Provide a longer summary of what this dataset is. -->
+The modifications made the original SQuAD v1 dataset:
+* Preprocess the text to have only English letters and some basic punctuation marks.
+* Punctuation marks are separated from the adjacent words (i.e: hello! -> hello !)
+* Remove context length greater than 175 tokens (this removes around 20% of the original dataset)
+* Remove questions and answers longer than 30 tokens (this removes around 140 examples from the original dataset)
