Although a tricky term – crowdsourcing can be defined as ‘enlisting a crowd of humans to help solve a problem defined by the system owners’.
Accordingly, there are four questions that are asked in a crowdsourcing project:
- How to recruit and retain users?
- What contributions can users make?
- How to combine user contributions to solve the target problem?
- How to evaluate users and their contributions?
Web based crowdsourcing projects benefit from a large amount of potential users, creative and sophisticated social tools, analytical software and easy user management.
