Local or Global: The Variation in the Encoding of Style Across Sentiment and Formality

Research on textual style transfer has observed that the concept of style can vary across domains. This research examines the encoding of style across the sentiment and formality domains and observes that formality appears to be more globally encoded, and sentiment more locally encoded. The work also shows how the encoding of a style can inform the appropriate choice of method to compute content preservation during textual style transfer.
