Iterative Paraphrastic Augmentation with Discriminative Span Alignment

Abstract: We introduce a novel paraphrastic augmentation strategy based on sentence-level lexically constrained paraphrasing and discriminative span alignment. Our approach allows for the large-scale expansion of existing datasets or the rapid creation of new datasets using a small, manually produced seed corpus. We demonstrate our approach with experiments on the Berkeley FrameNet Project, a large-scale language understanding effort spanning more than two decades of human labor. With four days of training data collecti… Show more

“…Insertion Figure 1: An example that illustrates monolingual word alignment (shown as arrows) can support analysis of human editing process and training of text generation models ( §6.1), such as for simplifying complex sentences for children to read. (Culkin et al, 2021) when combined with paraphrase generation.…”

“…Tsujii (2017, 2020) utilized constituency parsers for compositional and non-compositional phrase alignments. Culkin et al (2021) considered span alignment for FrameNet (Baker et al, 1998) annotations and treated each span pair as independent prediction.…”
