Bossa overview

Bossa is a software framework for "distributed thinking" - the use of volunteers on the Internet to perform tasks that require human intelligence, knowledge, or cognitive skills. Examples of such projects include Stardust@home and GalaxyZoo?. Bossa serves roughly the same function as Amazon's Mechanical Turk, but is simpler and more powerful, and is open source.

Volunteers have different skill levels; they may do tasks well or poorly. Some of them may intentionally do tasks incorrectly. One can achieve an overall level of accuracy that is higher than the population average using replication - having multiple volunteers do each task, and comparing the results. Replication is also useful for tasks that do not have a unique correct answer, and for which you want to collect alternatives.
