Abstract
Identifying toxic comments online is a key capability for facilitating productive discourse. Kaggle recently hosted a Toxic Comment Classification Challenge competition with the objective of identifying types of toxic comments, such as threats, obscenity, insults, and identity-based hate. In this presentation, Ryan Chesler will give an overview of his work on this project, where he ultimately placed 3rd out of 4551. Ryan will start by covering some basics of how words are embedded as numbers, including Word2Vec using Gensim and the sklearn packages CountVectorizer and TfidfVectorizer. Thereafter, he'll move to more advanced topics and discuss the models he used for the Toxic Comment challenge--what worked and what didn’t work. This talk will have content for both beginners and more advanced people, and code snippets and visualization will be available for download.
