Contribution
The proposed omnivorous model effectively combines different data types to improve formality transfer and can be adapted to other style transfer tasks.
Findings
Achieved state-of-the-art performance on formality transfer benchmark.
Successfully adapted to sentiment transfer with competitive results.
Demonstrated effectiveness of hybrid data approach in style transfer.
Abstract
Formality style transformation is the task of modifying the formality of a given sentence without changing its content. Its challenge is the lack of large-scale sentence-aligned parallel data. In this paper, we propose an omnivorous model that takes parallel data and formality-classified data jointly to alleviate the data sparsity issue. We empirically demonstrate the effectiveness of our approach by achieving the state-of-art performance on a recently proposed benchmark dataset of formality transfer. Furthermore, our model can be readily adapted to other unsupervised text style transfer tasks like unsupervised sentiment transfer and achieve competitive results on three widely recognized benchmarks.
