Crowdsourcing has emerged as an important paradigm in human
problem-solving techniques on the Web. One application of crowdsourcing
is to outsource certain tasks to the crowd that are difficult to
implement in software. Another potential benefit of crowdsourcing is
the on-demand allocation of a flexible workforce. Businesses may outsource
tasks to the crowd based on temporary workload variations. A
major challenge in crowdsourcing is to guarantee high-quality processing
of tasks. We present a novel crowdsourcing marketplace that matches
tasks to suitable workers based on auctions. The key to ensuring high
quality lies in skilled members whose capabilities can be estimated correctly.
We present a novel auction mechanism for skill evolution that
helps to correctly estimate workers and to evolve skills that are needed.
Evaluations show that this leads to improved crowdsourcing.
