根据成员间关系的强弱给社会网络中各边赋予权重,将二元网络扩展到边权网络,提出一种新的度量指标.该指标通过累加一个成员在网络中成为关键点的次数来度量其删除后给整个网络带来的损害程度,从而判断该成员对维护网络运行绩效的重要性.通过组织沟通网络的实例分析,说明新指标可以从维护网络安全的视角,有效辨识那些虽然结构位置不显著,但对网络安全具有重大隐患的重要成员.
根據成員間關繫的彊弱給社會網絡中各邊賦予權重,將二元網絡擴展到邊權網絡,提齣一種新的度量指標.該指標通過纍加一箇成員在網絡中成為關鍵點的次數來度量其刪除後給整箇網絡帶來的損害程度,從而判斷該成員對維護網絡運行績效的重要性.通過組織溝通網絡的實例分析,說明新指標可以從維護網絡安全的視角,有效辨識那些雖然結構位置不顯著,但對網絡安全具有重大隱患的重要成員.

To identify important members is a crucial problem in social network analysis. Indexes that are now used to measure the importance of members apply only to simple binary social networks, in which the social relation strength can be expressed by 0 or 1. Weights were assigned to social links according to the pairwise relation strength and a new index of the measure was given which is applicable to highlight important members embedded in an edge-weight network. An application in an organization network is also proposed. Results show that in edge-weight social networks the new measure works well in identifying some important members with which attribute-based centrality measures have difficulties.
