MOODTRAC IS NOT CURRENTLY RUNNING
The image below is the result a small python-driven app that attempts to plot the mood of twitter posts geotagged in the north american region.
The coastlines, projection, etc. are all in rough form currently. If there's enough interest, I can make the data ranges and map interactive, but for now all you get is a single image.
Below is the average ( for 1 hour of data ) mood vs. time.
For now this is a very simple toy that updates itself roughly ever 60 seconds. Positive values are for good/happy/positive moods and negative are the opposite.
The approach is simple bag of words, so it's fairly brain-dead. Mood is roughly the positive words vs. the negative words. The average on the map view is for all time. The graph average represents the last hour worth of observations. If I have some spare time, I'll work on improving the sentiment analaysis as well as pull in a variety of indicators from the economy, news, crime, etc.
