Macro-Task in Crowdsourcing

Crowdsourcing is an effective paradigm for human-powered problem.
In data-intensive tasks, one common usage of crowdsourcing is to annotate a set of data items which computer algorithms is hard to understand. Recently, many ‘crowd-powered’ algorithms have been proposed incorporating human abilities as a processing unit into computer algorithms to solve problems.
Another important usage of crowdsourcing is to collect new data or improve existing datasets. Based on crowdsourcing mechanism, we can get relatively high-quality datasets with low cost and latency.
We consider collecting structured data via crowdsourcing.
