In this project, we try to understand how street gang members (self-identified street gang members on Twitter) use social media. We have developed machine learning models to automatically identify street gang members’ Twitter profiles using the content they share on social media (such as tweets and YouTube videos), profile descriptions, profile/cover images, and their emoji usage.EmojiNet and Emoji Understanding
The goal of this project is to build tools and algorithms to improve machine understandability of emoji. We built the first machine-readable sense inventory for emoji called EmojiNet and currently working on emoji similarity and emoji sense disambiguation applications.Context-Aware Harassment Detection on Social Media
The aim of this project is to develop comprehensive and reliable context-aware techniques to glean information about the people involved and their interconnected network of relationships to determine and evaluate potential harassment and harassers. My work focuses on automatically classifying aggressive tweets posted on Twitter.Contrast Pattern Mining Aided Clustering (December 2015 - September 2011)
I explored developing a contrast pattern-based clustering algorithm for Abbreviation Disambiguation in unlabelled clinical data. I have also worked on contrast pattern aided Ontology Alignment (focused on classes) for Linked Open Data.
