June 25, 2018, Stanford University, California


1​st​ International Workshop on Emoji Understanding and Applications in Social Media
Co-located with The 12​th​ International AAAI Conference on Web and Social Media (ICWSM-18)


Pictographs, commonly referred to as "emoji", have become a popular way to enhance electronic communication. With their introduction in the late 1990's, emoji have been widely used to enhance the sentiment, emotion, and sarcasm expressed in social media messages. They often play distinct social and communicative roles compared to other forms of written language while taking over language constructs such as slang terms and emoticons. The ability to automatically process, derive meaning, and interpret text fused with emoji will be essential as society embraces emoji as a standard form of online communication. Yet the pictorial nature of emoji, the fact that (the same) emoji may be used in different contexts to express different meanings, and that emoji are used in different cultures and communities over the world who interpret emoji differently, make it especially difficult to apply traditional Natural Language Processing (NLP) techniques to analyze them. To meet these challenges, Emoji aims to stimulate research on understanding social, cultural, communicative, and linguistic roles of emoji and developing novel approaches to analyze, interpret and understand emoji and their usage in social media applications. It provides a forum to bring together researchers and practitioners from both academia and industry in the areas of social network analysis and mining, natural language processing, computational linguistics, human-computer interaction, and computational social sciences to discuss high-quality research and emerging applications, to exchange ideas and experience, and to identify new opportunities for collaboration.

With the rise of social media, emoji have become an extremely popular form of communication in social media. They are equally popular across major social media sites including Facebook, Instagram, and Twitter. As of 2017, Facebook and Facebook Messenger process over 60 million and 6 billion messages with emoji per day, respectively. In 2015, Instagram reported that nearly half of the photo comments posted on Instagram contains emoji and Instagram users tend to replace slang terms using emoji in photo comments. Another study revealed that emoji are slowly taking over emoticons on Twitter. Emoji data generated on social media sites have been utilized to study how emoji are used across different languages, cultures, user communities and as features to learn machine learning models to solve problems that span across many applications, including sentiment analysis, emotion analysis, and sarcasm detection. The ability to automatically process, derive meaning, and interpret text fused with emoji will be essential as society embraces emoji as a standard form of online communication. Thus, Emoji tries to bring together computer and social science researchers and practitioners from both academia and industry to discuss and exchange ideas on understanding social, cultural, communicative, and linguistic roles of emoji while leading the discussions on building novel computational methods to understand and interpret them.

Emoji is focused on research and discussions on challenges in emoji understanding, including but not limited to the following research directions.

  1. Challenges in interpreting the meaning of an emoji in a message context
  2. Novel methods for emoji sense disambiguation
  3. Novel methods for calculating emoji similarity
  4. Novel methods for emoji prediction
  5. Challenges in using emoji as a language
  6. Emoji’s effects on the evolution of language constructs used on social media such as emoticons and slang terms
  7. Common emoji usages in social media
  8. Cultural and community-specific emoji meaning evolution and interpretation
  9. Why emoji meanings change over time and across communities?
  10. Distinct social and communicative roles of emoji
  11. How do people come to understandings of the meanings of the emoji?
  12. Understanding sender intention and receiver interpretation of emoji
  13. Emoji rendering and interface design challenges
  14. Applications of emoji in social media
  15. Research related to other pictorial representations such as emoticons, kaomoji, emotes, customized emoji (e.g., bitmoji), and animated gifs

We encourage submissions (full research papers, short papers, and demo proposals) that utilize quantitative, qualitative and mixed research methods to approach the above challenges as contributions. For more information on how to prepare and submit papers including LaTeX templates, submission website etc., please check the paper submission instructions below.


We invite regular technical papers (8 pages), short papers (4 pages), and demo proposals (2 page). Submissions must be original and should not have been published previously or be under consideration for publication while being evaluated for this workshop. Submissions will be evaluated by the program committee based on the quality of the work and its fit to the workshop themes. All submissions should be double-blind and use the Emoji2018 LaTeX template (based on CEUR-WS templates) for formatting. A high-resolution PDF of the paper should be uploaded to the EasyChair submission site before the paper submission deadline.
