Abstract
This thesis project presents a persuasive reputation-based social game named ReputationForge, aiming at increasing the participants engagement in the team wikis of two different working environments. The result of an extensive conceptual investigation into a range of behavioral studies and existing reputation-based systems led to the final concept of ReputationForge. Aspects like community/social, reputation, personal-enjoyment and self-fulfillment are the main ingredients of the concept. In more detail, ReputationForge promotes a soft competition between the participants, who are divided into newbies and advanced ones. Participants start, and further complete tasks, that are related with the every-day work in the team wiki, such as creating or improving articles, and rating them. Tasks a re to be fulfilled individually and their successful completion awards participants karma points that increase their overall reputation. Clear feedback related to the progress of each task is given. Last but not least, ReputationForge introduces triggers, which help making the underlying wiki more visible and thus attracting users to keep coming back to it. An evaluation in two case studies (ebbits and Moknow) was performed in combination with a control group field study. It showed an increased engagement of the experimental group in the wiki of both case studies, thus proving evidence that a social-game approach based on reputation can actually increase the participants engagement in a corporate/team wiki. Still, the experimental group of ebbits registered a statistically significant increase in the majority of cases, while there was no statistically significant increase (except the number of rated articles) for the experimental group of Moknow. The result in the latter study can be attributed to a short evaluation time, a well established wiki, and the further involvement of the participants of the control group in the existing system Moknowpedia.
