+## Dataset Description
+
+TQuad2 is originally [released](https://huggingface.co/datasets/erdometo/tquad2) by [Erdem Metin](https://huggingface.co/erdometo) for Turkish.
+
+### Dataset Structure
+
+The original dataset only had `train` and `validation` split. We applied the following splitting methodology to obtain the `test` split:
+
+* If a train-val-test split is available, we use the existing divisions as provided.
+* For datasets with a train-test split only, we create a val split from the training set, sized to match the test set, and apply this across all models.
+* In cases with a train-val split, we reassign the val set as the test split, then generate a new val split from the training data following the approach above.
+* In cases with a val-test split, we split validation into train and vad sets in 80\% and 20\% proportions, respectively.
+* When only a single combined split is present, we partition the data into train, val, and test sets in 70\%, 15\%, and 15\% proportions, respectively.
+
+### Data Fields
+
+- **context** (string): The passage or paragraph in which the answer to the question can be found.
+- **question** (string): The question being asked.
+- **answers** (list): Each item in the list is a dictionary with the keys:
+  - **answer_start** (int): The character position in the context where the answer begins.
+  - **text** (string): The answer text.
+
+  Example: `[{ "answer_start": 47, "text": "28 Şubat 1702, Mekke" }]`
