Participation is a fundamental concept in information systems research. It has been viewed to be a promising factor for the success of any IT system. However, its complex nature with respect to its conceptualization and measurement reported mix findings to the literature. In this paper, a literature review is conducted across many research disciplines to find a solid ground for proposing definition and new measures for assessing computer-recorded (e.g. online) participation. Specifically, this paper redefines traditional views on IS-related participation into a new conceptualization, and proposes methods for its operationalization to appropriately fit within recent technological contexts such as information markets.
