Detecting Cyberbullying using Latent Semantic Indexing
Jacob L. Bigelow, April Edwards, Lynne Edwards · 2016
Cyberbullying has proven consequential to youth Internet users and previous methods relied heavily on the use of manually developed dictionaries. This project describes preliminary results for a system that uses Latent Semantic Indexing (LSI) for the detection of cyberbullying in a labeled collection of posts from Formspring.me. After preprocessing to account for variations in spelling and use of emoticons, a search system was developed. Our system significantly outperforms the baseline with a very simple query and is not dependent on a dictionary of bullying terms.
