Trust Evaluation Mechanisms for Wikipedia

Wikipedia is the well-nigh successful and most popular free encyclopedia developed by many editors in collaborative manner. It provides multitude of opportunities for online large scale knowledge sharing between virtual communities by letting the viewer to create and edit articles directly in the web browser. Information on Wikipedia is expanding largely, but the increase in quantity is not proportional to quality of the content. The cursory observer of Wikipedia may not be able to differentiate between the good and the bad quality of the content. Despite the success of Wikipedia, trust on Wikipedia content is still questioned because of its open editing model. In this paper primarily the challenges for trust evaluation mechanisms, caused by the significant characteristics of Wikipedia’s knowledge base are discussed. Existing Wikipedia trust evaluation models are comprehensively surveyed and key issues related to these are highlighted. Finally based on this study new dimensions for effective trust evaluation mechanisms are proposed, which are aimed to setup clear goals for future research in this area.
