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 it is simpler and more powerful, and it is open source.

Replication

Volunteers have different skill levels; they may do tasks well or poorly. Some of them may actually intentionally do tasks incorrectly. To achieve an over level of accuracy that is higher than the population average, we can use 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.
