Contrastive Domain Adaptation for Question Answering using Limited Text Corpora

Understand

Question generation has recently shown impressive results in customizing question answering (QA) systems to new domains.

• These approaches circumvent the need for manually annotated training data from the new domain and, instead, generate synthetic question-answer pairs that are used for training.
• However, existing methods for question generation rely on large amounts of synthetically generated datasets and costly computational resources, which render these techniques widely inaccessible when the text corpora is of limited size.
• This is problematic as many niche domains rely on small text corpora, which naturally restricts the amount of synthetic data that can be generated.
