Demo: How to use in HuggingFace Transformers

Requires Transformers: pip install transformers

from datasets import load_dataset
from transformers import AutoTokenizer, AutoModelForSequenceClassification, pipeline

path_model = "qanastek/FrenchMedMCQA-BART-base-Wikipedia-BM25"

tokenizer = AutoTokenizer.from_pretrained(path_model)
model = AutoModelForSequenceClassification.from_pretrained(path_model)

pipeline = pipeline(task="summarization", model=model, tokenizer=tokenizer) # CPU

dataset  = load_dataset("qanastek/FrenchMedMCQA")["test"]

for e in dataset:
    prediction = pipeline(source, truncation=True, max_length=900)[0]["summary_text"]

Output:

Training data

The questions and their associated candidate answer(s) were collected from real French pharmacy exams on the remede website. Questions and answers were manually created by medical experts and used during examinations. The dataset is composed of 2,025 questions with multiple answers and 1,080 with a single one, for a total of 3,105 questions. Each instance of the dataset contains an identifier, a question, five options (labeled from A to E) and correct answer(s). The average question length is 14.17 tokens and the average answer length is 6.44 tokens. The vocabulary size is of 13k words, of which 3.8k are estimated medical domain-specific words (i.e. a word related to the medical field). We find an average of 2.49 medical domain-specific words in each question (17 % of the words) and 2 in each answer (36 % of the words). On average, a medical domain-specific word is present in 2 questions and in 8 answers.
