T5 Question Generation and Question Answering

Model description

This model is a T5 Transformers model (airklizz/t5-base-multi-fr-wiki-news) that was fine-tuned in french on 3 different tasks

• question generation

• question answering

• answer extraction

It obtains quite good results on FQuAD validation dataset.

Intended uses & limitations

This model functions for the 3 tasks mentionned earlier and was not tested on other tasks.

from transformers import T5ForConditionalGeneration, T5Tokenizer
model = T5ForConditionalGeneration.from_pretrained("JDBN/t5-base-fr-qg-fquad")
tokenizer = T5Tokenizer.from_pretrained("JDBN/t5-base-fr-qg-fquad")

Training data

The initial model used was https://huggingface.co/airKlizz/t5-base-multi-fr-wiki-news. This model was finetuned on a dataset composed of FQuAD and PIAF on the 3 tasks mentioned previously.

The data were preprocessed like this

• question generation: "generate question: Barack Hussein Obama, né le 4 aout 1961, est un homme politique américain et avocat. Il a été élu <hl> en 2009 <hl> pour devenir le 44ème président des Etats-Unis d'Amérique."

• question answering: "question: Quand Barack Hussein Obamaa-t-il été élu président des Etats-Unis d’Amérique? context: Barack Hussein Obama, né le 4 aout 1961, est un homme politique américain et avocat. Il a été élu en 2009 pour devenir le 44ème président des Etats-Unis d’Amérique."

• answer extraction: "extract_answers: Barack Hussein Obama, né le 4 aout 1961, est un homme politique américain et avocat. <hl> Il a été élu en 2009 pour devenir le 44ème président des Etats-Unis d’Amérique <hl>."

The preprocessing we used was implemented in https://github.com/patil-suraj/question_generation

Eval results

On FQuAD validation set

Question Answering metrics

For these metrics, the performance of this question answering model (https://huggingface.co/illuin/camembert-base-fquad) on FQuAD original question and on T5 generated questions are compared.
