About Me

I'm Felipe José Bravo Márquez, I was born in 3th January 1984 on Santiago, Chile. I am currently studying a PhD in computer science at the University of Waikato in the Machine Learning Group. My supervisors are professors Bernhard Pfahringer and Eibe Frank.

In my research thesis I investigate algorithms for sentiment analysis in time-evolving social media streams. You can find more information about the Twitter lexicon expansion project here.
