Model Card of lmqg/flan-t5-small-squad-qag

This model is fine-tuned version of google/flan-t5-small for question & answer pair generation task on the lmqg/qag_squad (dataset_name: default) via lmqg.

Overview

• Language model: google/flan-t5-small
• Language: en
• Training data: lmqg/qag_squad (default)
• Online Demo: https://autoqg.net/
• Repository: https://github.com/asahi417/lm-question-generation
• Paper: https://arxiv.org/abs/2210.03992

Usage

• With lmqg

from lmqg import TransformersQG

# initialize model
model = TransformersQG(language="en", model="lmqg/flan-t5-small-squad-qag")

# model prediction
question_answer_pairs = model.generate_qa("William Turner was an English painter who specialised in watercolour landscapes")

• With transformers

from transformers import pipeline

pipe = pipeline("text2text-generation", "lmqg/flan-t5-small-squad-qag")
output = pipe("generate question and answer: Beyonce further expanded her acting career, starring as blues singer Etta James in the 2008 musical biopic, Cadillac Records.")
