  sub:paragraph c4o:hasContent "A contest reaches out to a crowd to solve a given problem and rewards the best ideas. It exploits competition and intellectual challenge as main drivers for participation. The idea, originating from open innovation, has been employed in many domains, from creative industries to sciences, for tasks of varying complexity (from designing logos to building sophisticated algorithms). In particular, contests as means to successfully involve experts in advancing science have a long-standing tradition in research, e.g., the Darpa challenges 3 and NetFlix. 4 Usually, contests as crowdsourcing mechanisms are open for a medium to long period of time in order to attract high quality contributions. Contests may apply different reward models, but a common modality is to define one main prize for the contest winner." ;
