A few projects are currently active on my plate, but recently, I helped Lichen produced a Sentiment Analysis project on the Twittersphere of Radio-Canada’s (the french branch of the CBC) TV shows, personalities and events.

We faced few challenges regarding the definition of the sentiment dimensions, the language parsing issue and the power distribution of tweets among the users. Overall, we were able to deliver a global sentiment index based on Twitter activity and sentiment, and charted different time series regarding the more granular sentiments.

This project is available in french at http://indice.ici.ca.
