Abstract: Online information seekers increasingly utilise the online encyclopaedia Wikipedia as a key reference source. Wikipedia|s special feature is that it is based on the collective intelligence (CI) of lay citizens. Its consensus-building participatory knowledge-building processes replace traditional encyclopaedia processes founded on the knowledge of experts and gatekeeping practices. However there have been reports of concerns with the level of information quality provided by Wikipedia articles. This paper explores information quality for Wikipedia theoretically. First, it conceptualises the Wikipedia model of knowledge production and second, it analyses information quality for the model. Finally, the paper recommends some improvements for the model and discusses other implications for knowledge management theory and practice.

Keywords: Wikipedia; collective intelligence; information quality; online information; internet; world wide web; citizen involvement; consensus-building; participatory knowledge-building; encyclopaedias; experts; gatekeeping; knowledge management; KM.
