A Semantics-Based Measure of Emoji Similarity

Emoji have grown to become one of the most important forms of communication on the web. With its widespread use, measuring the similarity of emoji has become an important problem for contemporary text processing since it lies at the heart of sentiment analysis, search, and interface design tasks. This paper presents a comprehensive analysis of the semantic similarity of emoji through embedding models that are learned over machine-readable emoji meanings in the EmojiNet knowledge base. Using emoji descriptions, emoji sense labels and emoji sense definitions, and with different training corpora obtained from Twitter and Google News, we develop and test multiple embedding models to measure emoji similarity. To evaluate our work, we create a new dataset called EmoSim508, which assigns human-annotated semantic similarity scores to a set of 508 carefully selected emoji pairs. After validation with EmoSim508, we present a real-world use-case of our emoji embedding models using a sentiment analysis task and show that our models outperform the previous best-performing emoji embedding model on this task. The EmoSim508 dataset and our emoji embedding models are publicly released with this paper and can be downloaded from http://emojinet.knoesis.org/.Comment: This paper is accepted at Web Intelligence 2017 as a full paper, In 2017 IEEE/WIC/ACM International Conference on Web Intelligence (WI).

The Meme as Post-Political Communication Form: A Semiotic Analysis

The 2016 American Presidential Election was a point of great upheaval in the consciousness of many. To many it signified the defeat of the previous global liberal paradigm and a weakening of the traditional ways in which we organize ourselves politically and socially. While most of culture undergoes mediation through the internet- political processes are no exception. This paper aims to analyze how modern political discourses and organizing occur online, and how often politics occurs at the level of memetic communications. The analysis hinges upon studying the history of political memes such as Pepe and the relationship between the news and politics. But it ultimately culminates with the relationship between performing authenticity on the political field and subcultural signifiers such as memes
