# mlqa filtered version

For a better dataset description, please visit the official site of the source dataset: [LINK](https://huggingface.co/datasets/mlqa) <br>
<br>
**This dataset was prepared by converting mlqa dataset**. I've concatenated versions of the dataset for languages of interest and retrieved a text answers from "answers" column. 

**I additionaly share the code which I used to convert the original dataset to make everything more clear**
```
def download_mlqa(subset_name):
    dataset_valid = load_dataset("mlqa", subset_name, split="validation").to_pandas()
    dataset_test  = load_dataset("mlqa", subset_name, split="test").to_pandas()
    full_dataset = pd.concat([dataset_valid, dataset_test])
    full_dataset.reset_index(drop=True, inplace=True)
    return full_dataset

needed_langs = ["mlqa.en.en", "mlqa.de.de", "mlqa.ar.ar", "mlqa.es.es", "mlqa.vi.vi", "mlqa.zh.zh"]
datasets = []
for lang in tqdm(needed_langs):
    dataset = download_mlqa(lang)
    dataset["lang"] = lang.split(".")[2]
    datasets.append(dataset)
    
full_mlqa = pd.concat(datasets)
full_mlqa.reset_index(drop=True, inplace=True)
full_mlqa["answer"] = [answer_dict["text"][0] for answer_dict in full_mlqa["answers"]]
full_mlqa.drop("answers", axis=1, inplace=True)
```

**How to download**

```
from datasets import load_dataset
data = load_dataset("dkoterwa/mlqa_filtered")
