A Bounded Confidence Approach to Understanding User Participation in Peer Production Systems

摘要: Commons-based peer production does seem to rest upon a paradox. Although users produce all contents, at the same time participation is commonly on voluntary basis, and largely incentivized by achievement of project's goals. This means that have coordinate their actions goals, in order keep themselves from leaving. While this situation easily explainable for small groups highly committed, like-minded individuals, little known about large-scale, heterogeneous projects, such as Wikipedia. In contribution we present model large online community. The features dynamic population bounded confidence users, an endogenous process user departure. Using global sensitivity analysis, identify most important parameters affecting lifespan participation. We find presents two distinct regimes, shift between them governed parameter. For low values parameter, depart almost immediately. high values, however, produces bimodal distribution lifespan. These results suggest communities could be explained terms group consensus, provide novel connection models opinion dynamics commons-based production.
