+
+### Dataset Summary
+
+***Xtr-WikiQA*** is an Answer Sentence Selection (AS2) dataset in 9 non-English languages, proposed in our paper accepted at ACL 2023 (Findings): **Cross-Lingual Knowledge Distillation for Answer Sentence Selection in Low-Resource Languages**.
+This dataset is based on an English AS2 dataset, WikiQA ([Original](https://msropendata.com/datasets/21032bb1-88bd-4656-9570-3172ae1757f0), [Hugging Face](https://huggingface.co/datasets/wiki_qa)).
+For translations, we used [Amazon Translate](https://aws.amazon.com/translate/).
+
+### Languages
+
+- Arabic (ar)
+- Spanish (es)
+- French (fr)
+- German (de)
+- Hindi (hi)
+- Italian (it)
+- Japanese (ja)
+- Dutch (nl)
+- Portuguese (pt)
+
+File location: [`tsv/`](./tsv/)
+
+## Dataset Structure
+
+### Data Instances
+
+This is an example instance from the Arabic training split of Xtr-WikiQA dataset. 
+
+```
+{
+  "QuestionID": "Q1",
+  "Question": "كيف تتشكل الكهوف الجليدية؟",
+  "DocumentID": "D1",
+  "DocumentTitle": "كهف جليدي",
+  "SentenceID": "D1-0",
+  "Sentence": "كهف جليدي مغمور جزئيًا على نهر بيريتو مورينو الجليدي.",
+  "Label": 0
+}
+```
+
+All the translated instances in tsv files are listed in the same order of the original (native) instances in the WikiQA dataset.
+
+For example, the 2nd instance in [`tsv/ar-train.tsv`](./tsv/ar-train.tsv) (Arabic-translated from English)
+corresponds to the 2nd instance in [`WikiQA-train.tsv`](https://msropendata.com/datasets/21032bb1-88bd-4656-9570-3172ae1757f0) (English).
+
+### Data Fields
+
+Each instance (a QA pair) consists of the following fields:
+
+- `QuestionID`: Question ID (str)
+- `Question`: Question to be answered (str)
+- `DocumentID`: Document ID (str)
+- `DocumentTitle`: Document title (str)
+- `SentenceID`: Answer sentence in the document (str)
+- `Sentence`: Answer sentence in the document (str)
+- `Label`: Label that indicates the answer sentence correctly answers the question (int, 1: correct, 0: incorrect)
+
+
+### Data Splits
+
+|                   |             | **#Questions** |          |   |           | **#Sentences** |          |
+|-------------------|------------:|---------------:|---------:|---|----------:|---------------:|---------:|
+|                   |   **train** |        **dev** | **test** |   | **train** |        **dev** | **test** |
+| **Each language** |         873 |            126 |      243 |   |     8,671 |          1,130 |    2,351 |
