Discourse anaphoricity vs. perspective sensitivity in emoji semantics

This paper aims to provide a foundation for studying the interplay between emoji and linguistic (natural language) expressions; it does so by proposing a formal semantic classification of emojitext combinations, focusing on two core sets of emoji: face emoji and activity emoji. Based on different data sources (introspective intuitions, naturalistic Twitter examples, and experimental evidence), we argue that activity emoji (case study I) are essentially event descriptions that serve as separate discourse units (similar to free adjuncts) and connect to the accompanying (linguistic) text by virtue of suitable discourse relations. By contrast, face emoji (case study II) are expressive elements that are anchored to an attitude holder and comment on a proposition provided by the accompanying text. We provide further evidence for the distinct behavior of face emoji and activity emoji by looking at their scopal behavior with respect to linguistically expressed negation. In particular, we probe interactions of emoji and texts that contain clausal negation, and conclude that both face emoji and activity emoji generally do not scope under negation. However, the appearance of such a scope relation arises with activity emoji when the emoji are connected to the accompanying text by virtue of an Explanation discourse relation. With face emoji, scopal interactions seem to appear in cases where the default interpretation would result in a discourse contribution that is pragmatically infelicitous, and also in cases that involve a specialized emoji-repetition construction where a repeated alternation of face emoji with words assumes a scope-marking role.
