Scala Days 2015 Pulse – Sentiment Analysis of the Sessions


As you might have read that the Pulse Application from Knoldus created a flutter at Scala Days 2015. In this post let us dig deeper into some findings. We are already getting some cool requests to open source the code which we would do soon. We would just like to strip out the dictionaries that we have used.

Overall the conference was very positive sentiment wise. There were around 37% positive tweets detected and less than 4% negative sentiments detected.

Roland Kuhn‘s excellent session on Actors vs Types got an undue amount of negative tweets just because people were not able attend his session. The room was packed to capacity and still many people wanted to get in. The conference organizers got into action quickly and announced another session for the wonderful speaker for all the people who could not attend.

Dean Wampler‘s Spark session was famous as expected. So were the sessions from Adam Gibson and Amanda Laucher.
