A bridge is a type of social tie that connects two different groups in a social network. ==General bridge== In general, a bridge is a direct tie between nodes that would otherwise be in disconnected components of the graph.〔Ahn, Luis von. "Thresholds and Collective Action." Sept. 16, 2008. http://scienceoftheweb.org/15-396/lectures/lecture07.pdf〕 This means that say that A and B make up a social networking graph, is in A, is in B, and there is a social tie between and . If were to be removed, A and B would become disconnected components of the graph. This means that is a bridge. For example, A could represent a corporation and B Congress. could then be a lobbyist and a Congressman. would then represent the relationship between that corporation and Congress that only exists through the lobbyist. This is very similar to the concept of a bridge in graph theory, but with special social networking properties such as strong and weak ties. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Bridge (interpersonal)」の詳細全文を読む スポンサード リンク
