Allow node filtering by node colors for SocNetV
This is not the same as filtering by aggregating.
SocNetV should be able to visualize nodes'prominence by using hue (from red to blue) See http://en.wikipedia.org/wiki/Centrality#mediaviewer/File:Graph_betweenness.svg
Provide methods for analyzing the social prosition/role of actors and their structural similarities for SocNetV
SocNetV should offer the user procedures for analyzing the social prosition/role of nodes and their structural similarities. The user should be able to identify subsets of similar nodes by performing: - basic positional analysis using measures based on the mathematical notion of structural equivalence (i.e. Eucli...

Katz centrality computes the relative influence of a node within a network by measuring the number of the immediat...
