Model Card for QAmembert-large

Model Description

We present QAmemBERT, which is a CamemBERT large fine-tuned for the Question-Answering task for the French language on four French Q&A datasets composed of contexts and questions with their answers inside the context (= SQuAD 1.0 format) but also contexts and questions with their answers not inside the context (= SQuAD 2.0 format). All these datasets were concatenated into a single dataset that we called frenchQA. This represents a total of over 221,348 context/question/answer triplets used to finetune this model and 6,376 to test it.
Our methodology is described in a blog post available in English or French.

All these datasets were concatenated into a single dataset that we called frenchQA.

Usage

Example with answer in the context

from transformers import pipeline

qa = pipeline('question-answering', model='CATIE-AQ/QAmembert-large', tokenizer='CATIE-AQ/QAmembert-large')

result = qa({
    'question': "Combien de personnes utilisent le français tous les jours ?",
    'context': "Le français est une langue indo-européenne de la famille des langues romanes dont les locuteurs sont appelés francophones. Elle est parfois surnommée la langue de Molière.  Le français est parlé, en 2023, sur tous les continents par environ 321 millions de personnes : 235 millions l'emploient quotidiennement et 90 millions en sont des locuteurs natifs. En 2018, 80 millions d'élèves et étudiants s'instruisent en français dans le monde. Selon l'Organisation internationale de la francophonie (OIF), il pourrait y avoir 700 millions de francophones sur Terre en 2050."
})

if result['score'] < 0.01:
    print("La réponse n'est pas dans le contexte fourni.")
else :
    print(result['answer'])

{'score': 0.9876325726509094,
 'start': 268,
 'end': 281,

Example with answer not in the context

from transformers import pipeline

qa = pipeline('question-answering', model='CATIE-AQ/QAmembert-large', tokenizer='CATIE-AQ/QAmembert-large')

result = qa({
    'question': "Quel est le meilleur vin du monde ?",
    'context': "La tour Eiffel est une tour de fer puddlé de 330 m de hauteur (avec antennes) située à Paris, à l’extrémité nord-ouest du parc du Champ-de-Mars en bordure de la Seine dans le 7e arrondissement. Son adresse officielle est 5, avenue Anatole-France.  
Construite en deux ans par Gustave Eiffel et ses collaborateurs pour l'Exposition universelle de Paris de 1889, célébrant le centenaire de la Révolution française, et initialement nommée « tour de 300 mètres », elle est devenue le symbole de la capitale française et un site touristique de premier plan : il s’agit du quatrième site culturel français payant le plus visité en 2016, avec 5,9 millions de visiteurs. Depuis son ouverture au public, elle a accueilli plus de 300 millions de visiteurs."
})

if result['score'] < 0.01:
    print("La réponse n'est pas dans le contexte fourni.")
else :
    print(result['answer'])

La réponse n'est pas dans le contexte fourni.

Environmental Impact

Carbon emissions were estimated using the Machine Learning Impact calculator presented in Lacoste et al. (2019). The hardware, runtime, cloud provider, and compute region were utilized to estimate the carbon impact.

• Hardware Type: A100 PCIe 40/80GB
• Hours used: 11h and 12min
• Cloud Provider: Private Infrastructure
• Carbon Efficiency (kg/kWh): 0.076kg (estimated from electricitymaps ; we take the average carbon intensity in France for the month of March 2023, as we are unable to use the data for the day of training, which are not available.)
• Carbon Emitted (Power consumption x Time x Carbon produced based on location of power grid): 0.20 kg eq. CO2
