# Dataset Card for WikiAnswers Duplicate Questions

This dataset contains duplicate questions from the [WikiAnswers Corpus](https://github.com/afader/oqa#wikianswers-corpus), formatted to be easily used with Sentence Transformers to train embedding models.

## Dataset Subsets

### `pair` subset

* Columns: "anchor", "positive"
* Column types: `str`, `str`
* Examples:
    ```python
    {
      'anchor': 'How many calories is in a handful of strawberries?',
      'positive': 'How many calories are in a strawberry popsickles?',
    }
    ```
* Collection strategy:  Reading the WikiAnswers dataset from [embedding-training-data](https://huggingface.co/datasets/sentence-transformers/embedding-training-data), which has lists of duplicate questions. I've considered all adjacent questions as a positive pair, plus the last and first caption. So, e.g. 5 duplicate questions results in 5 duplicate pairs.
* Deduplified: No
