Examining Collective Memory Building in Wikipedia: A Multilevel Network Approach

This study interprets Wikipedia as a memory place where independent contributors discuss and negotiate the meanings of past events in a collaborative way. We examine how interconnections between high-impact events lead to the differential patterns of collective memory building. The results show that the presence of a direct network tie between two events is related to a smaller difference in the patterns of collective memory building among Wikipedia users. In addition, a higher degree of structural equivalence between two events makes them more similar in terms of the patterns of collective memory building. Our findings reveal that the range of network effects is not confined within the local substructure but can extend to the global level as well. The results also confirm that Wikipedia editors will refer to the editing patterns of the events that have direct links or occupy similar structural positions with those they intend to contribute to.
