Emojis come with prepacked semantics making them great candidates to create new forms of more accessible communications.

Thus, we collected a crowdsourced dataset of one-word emoji descriptions for 1,289 emojis presented to participants with no surrounding text. The emojis and their interpretations were then examined for ambiguity. We find that with 30 annotations per emoji, 16 emojis (1.2 unambiguous, whereas 55 emojis (4.3 are indistinguishable from randomly chosen descriptions.

Furthermore, investigating the ambiguity of different types of emojis, we find that an important factor is the extent to which an emoji has an embedded symbolical meaning drawn from an established code-book of symbols. We conclude by discussing design implications.
