  Sentiment transfer is one popular example of a text style transfer task,
where the goal is to reverse the sentiment polarity of a text. With a sentiment
reversal comes also a reversal in meaning. We introduce a different but related
task called positive reframing in which we neutralize a negative point of view
and generate a more positive perspective for the author without contradicting
the original meaning. Our insistence on meaning preservation makes positive
reframing a challenging and semantically rich task. To facilitate rapid
progress, we introduce a large-scale benchmark, Positive Psychology Frames,
with 8,349 sentence pairs and 12,755 structured annotations to explain positive
reframing in terms of six theoretically-motivated reframing strategies. Then we
evaluate a set of state-of-the-art text style transfer models, and conclude by
discussing key challenges and directions for future work.
