= 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,
and a few 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.
