Emoji Use in Tweets: Relationships with Personality Traits and Word Usage  

Talk By: Dr. Shelia M. Kennison (Oklahoma State University) 

Abstract: Emojis are digital pictographs used to express ideas and emotions. We examined how emoji use on Twitter was related to 76 users’ language use and personality traits. With their consent, we retrieved tweets from accounts using the Twitter API and python script. We also analyzed word usage in tweets using the Linguistic Inquiry Word Count (LIWC). The results showed that frequent use of emojis was related to lower levels of openness, but not other Big Five traits. More frequent use of emojis was related to more frequent use of words related to tone, positive emotion, sad, affect, feel, you pronouns, family, and the body. More frequent use of emojis was related to less frequent use of articles and words related to insight, money, risk, anger, sexual, ingest, informal, and swear words. The results support efforts to create user profiles using the content of social media posts.
