We Feel Fine is the brainchild of ‘harvests’ human feelings (nice image ;-)) from weblogs by searching for the phrases “I feel” and “I am feeling” and then identifying the… “feeling” expressed in that sentence (e.g. happy, sad, lonely, depressed, etc.). Other info on age, gender, and geographical location is also extracted and saved. The results are collected in a database of several million human feelings, which increases by 15,000 – 20,000 new per day. Each feeling is then visualized as a particles. The formal properties of the particles (i.e. color, size, shape, opacity, etc.) denote the type of feeling that has been expressed. The data can also be used to visualize how bloggers in various cities compare in terms of their overall feelings.
