System Dynamics Modeling for Online Encyclopedias Based on Activity Theory

Different from prior empirical studies that usually investigate the unidirectional linear relationships among prominent factors in online Encyclopedias from a static perspective, this study captures a dynamic picture of their interrelations from a perspective of system dynamics. This study proposes a general activity system of online encyclopedias based on Engeström's activity theory and develops a holistic system dynamics model according to the system dynamics method proposed by Forrester. This study enriches our understanding of the intrinsic dynamic of knowledge collaboration in online encyclopedias and demonstrates the gains in understanding system co-evolution achievable by utilizing the system dynamics method in concert with the activity theory.
