Dataset Card for mlquestions

Dataset Summary

The MLQuestions dataset consists of questions from Google search queries and passages from Wikipedia pages related to Machine learning domain . The dataset was created to support research in domain adaptation of question generation and passage retrieval models.

Languages

The text in the dataset is in English

Dataset Structure

Data Instances

We release development and test sets where a typical data point comprises a passage denoted by input_text label and a question, with a target_text label.

An example from the MLQuestions test set looks as follows:

{ 'input_text': 'Bayesian learning uses Bayes' theorem to determine the conditional probability of a hypotheses given some evidence or observations.' 'target_text': 'What is Bayesian learning in machine learning' }

We also provide unsupervised questions and passages in two separate files - 'passages_unaligned.csv' and 'questions_unaligned.csv' with labels input_text and target_text respectively.

    abstract = "In this work, we introduce back-training, an alternative to self-training for unsupervised domain adaptation (UDA). While self-training generates synthetic training data where natural inputs are aligned with noisy outputs, back-training results in natural outputs aligned with noisy inputs. This significantly reduces the gap between target domain and synthetic data distribution, and reduces model overfitting to source domain. We run UDA experiments on question generation and passage retrieval from the Natural Questions domain to machine learning and biomedical domains. We find that back-training vastly outperforms self-training by a mean improvement of 7.8 BLEU-4 points on generation, and 17.6{\%} top-20 retrieval accuracy across both domains. We further propose consistency filters to remove low-quality synthetic data before training. We also release a new domain-adaptation dataset - MLQuestions containing 35K unaligned questions, 50K unaligned passages, and 3K aligned question-passage pairs.",
