End-to-End Sentiment Analysis of Twitter Data
We presented an end-to-end pipeline for sentiment analysis of Twitter data and showed that a hierarchal cascaded pipeline of three models to label a tweet as Objective, Neutral, Positive and Negative class is better than a 4-way classifier design.

Projects & Presentations

Visualizing Wikipedia using t-SNE
Presented an approach on visualizing high-dimensional data of Wikipedia using t-Distributed Stochastic Neighbor Embedding (t-SNE, specifically t-SNE using Barnes-Hut approximation). It was shown that using semantic role labels as features instead of bag of words, distinct clusters are formed for the historical human events.
Multi-Label Text Classification
Presented an approach to perform multi-label classification using Support Vector Machines which was evaluated on a subset of Large Scale Hierarchical Text Classification Challenge 4 dataset.
Presentation on Visualizing Text using t-SNE
Presented an overview on how t-SNE is useful in visualizing text, specially in Lensing Wikipedia.
Presentation on Semi-Supervised Learning
Presented an overview on various methods in semi-supervised learning at the SFU Machine Learning Reading Group.
Presentation on BRAT Rapid Annotation Tool
Presented an overview on BRAT an online environment for collaborative text annotation. The slides show the basic features available in BRAT and a demo was given on how to setup BRAT and how various types of annotations can be performed.
