It was a pleasure for me to present my paper with the topic „Components and Functions of Crowdsourcing Systems – A Systematic Literature Review“ at 11th International Conference on Wirtschaftsinformatik (WI2013) in Leipzig. The relevant literature that I found in my systematic literature review (SLR) as well as the derived concept map of crowdsourcing components and functions can be found in an additional document. If you have comments to my article or presentation at the WI2013 please let me know.
