Representation of the research question.

#	Research questions	Aims
1	What are the significant features of the crowd for effective crowdsourcing?	In the crowdsourcing environment, the participating crowd has some features that are significant for assigning a task. We will analyze many of these features to make crowdsourcing activity efficient and effective.
