Sentiment Quiz, a game for Facebook in the tradition of Games With A Purpose.

Team
Walter Rafelsberger (lead development)
Gerhard Wohlgenannt (content aggregation and annotation)
Reinhard Fischer (evaluation)
Clemens Költringer (evaluation and promotion)
Johannes Liegl (conceptualization)
and Arno Scharl (project lead).

I released some Sentiment Quiz updates today: New English terms were added to the database and we're doing a sprint challenge this fall.

Have a look at the game to see how many terms players have already evaluated. While you're at it, you could contribute a few evaluations of course :-).

The evaluations will be used to compare the generated Sentiment Dictionary against others with "expert" evaluations or sentiment algorithms. A great experiment to prove the power of crowdsourcing!
