# Dataset Card for Parallel Sentences - WikiMatrix

This dataset contains parallel sentences (i.e. English sentence + the same sentences in another language) for numerous other languages. Most of the sentences originate from the [OPUS website](https://opus.nlpl.eu/).
In particular, this dataset contains the [WikiMatrix](https://opus.nlpl.eu/WikiMatrix/corpus/version/WikiMatrix) dataset.

These datasets can be used to train multilingual sentence embedding models. For more information, see [sbert.net - Multilingual Models](https://www.sbert.net/examples/training/multilingual/README.html).

## Dataset Subsets

### `all` subset

* Columns: "english", "non_english"
* Column types: `str`, `str`
* Examples:
    ```python
    {
      "english": "I will go down with you into Egypt, and I will also surely bring you up again."",
      "non_english": "Аз ще бъда с тебе в Египет и Аз ще те изведа назад.""
    }
    ```
* Collection strategy: Combining all other subsets from this dataset.
* Deduplified: No

### `en-...` subsets

* Columns: "english", "non_english"
* Column types: `str`, `str`
* Examples:
    ```python
    {
      "english": "By Him Who is the Lord of mankind!",
      "non_english": "しかしながら人主の患はまた人を信ぜざるにもある。"
    }
    ```
* Collection strategy: Processing the raw data from [parallel-sentences](https://huggingface.co/datasets/sentence-transformers/parallel-sentences) and formatting it in Parquet, followed by deduplication.
* Deduplified: Yes
