我们介绍了三角洲中心，一类新的措施的结构中心的网络。特别是，我们专注于在这类措施，信息中心C-I，这是基于网络上的信息的有效传播的概念。C-I是为有值图和无值图定义的，适用于群体和个人。该措施的说明和比较标准的中心性措施，通过使用一个经典的网络数据集。通过考虑计算机生成的大型图和来自真实的世界的两个网络，研究了信息中心度的统计分布。
We introduce delta centralities, a new class of measures of structural centrality for networks. In particular, we focus on a measure in this class, the information centrality C-I, which is based on the concept of efficient propagation of information over the network. C-I is defined for both valued and non-valued graphs, and applies to groups as well as individuals. The measure is illustrated and compared with respect to the standard centrality measures by using a classic network data set. The statistical distribution of information centrality is investigated by considering large computer generated graphs and two networks from the real world.
