# Dataset information 
**Dataset concatenating QA datasets with context available in French and open-source.**  
In addition, an augmented version of these datasets has been added (same context but different questions to create data in SQuADv2 format).  
In total, there are 221,348 training data, **910** validation data and 6,376 test data (the first 3,188 rows correspond to SQuADv2 format, the remaining 3,188 to SQuADv2 format). 
In practice, due to the restrictive license for the FQUAD 1.0 dataset, we can only share **179,886** rows of the 221,348 training data and not the test dataset.  
Our methodology is described in a blog post available in [English](https://blog.vaniila.ai/en/QA_en/) or [French](https://blog.vaniila.ai/QA/).


#  Usage
```
from datasets import load_dataset
dataset = load_dataset("CATIE-AQ/frenchQA",sep=";")
```
```
dataset
DatasetDict({
    train: Dataset({
        features: ['context', 'question', 'answer', 'answer_start', 'dataset'],
        num_rows: 179886
    })
    validation: Dataset({
        features: ['context', 'question', 'answer', 'answer_start', 'dataset'],
        num_rows: 910
    })
})
```

- the `context` column contains the context
- the `question` column contains the question
- the `answer` column contains the answer (has been replaced by `no_answer` for rows in SQuAD v2 format)
- the `answer_start` column contains the start position of the answer in the context (has been replaced by `-1` for rows in SQuAD v2 format)
- the `dataset` column identifies the row's original dataset (if you wish to apply filters to it, rows in SQuAD v2 format are indicated with the suffix `_v2` in the dataset name)

## Split
- `train` corresponds to the concatenation of the training dataset from `pragnakalp/squad_v2_english_translated` + `lincoln/newsquadfr` + `PIAFv1.2` + the augmented version of each dataset in SQuADv2 format (no shuffle has been performed)
- `validation` corresponds to the concatenation of the newsquadfr validation dataset + this same dataset expanded in SQuAD v2 format (= newsquadfr_v2) (no shuffle performed)


# Question type statistics

The question type distribution is as follows:

| Type of question | Frequency in percent |
| -----------      | ----------- |
|What (que)        |55.02|
|Who (qui)         |15.96|
|How much (combien)|7.92|
|When (quand)      |6.90|
|Where (où)        |3.15|
|How (comment)     |3.76|
|What (quoi)       |2.60|
|Why (pourquoi)    |1.25|
|Other             |3.44|

The number of questions containing a negation, e.g. "What was the name of Chopin's first music teacher who was not an amateur musician?", is estimated at 3.55% of the total questions.


For information, the distribution of the complete dataset (containing FQUAD 1.0 and FQUAD 1.0 data in SQUAD 2.0 format) is as follows:

| Type of question | Frequency in percent |
| -----------      | ----------- |
|What (que)        |55.12|
|Who (qui)         |16.24|
|How much (combien)|7.56|
|When (quand)      |6.85|
|Where (où)        |3.98|
|How (comment)     |3.76|
|What (quoi)       |2.94|
|Why (pourquoi)    |1.41|
|Other             |2.14|

The number of questions containing a negation, e.g. "What was the name of Chopin's first music teacher who was not an amateur musician?", is estimated at 3.07% of the total questions.
