Domain Adaptation for Question Answering via Question Classification

Understand

Question answering (QA) has demonstrated impressive progress in answering questions from customized domains.

• Nevertheless, domain adaptation remains one of the most elusive challenges for QA systems, especially when QA systems are trained in a source domain but deployed in a different target domain.
• In this work, we investigate the potential benefits of question classification for QA domain adaptation.
• We propose a novel framework: Question Classification for Question Answering (QC4QA).
