SIMPLIFICATION OF LARGE NETWORKS AND GRAPHS

摘要

Embodiments relate to simplifying large and complex networks and graphs using global connectivity information based on calculated node centralities. An aspect includes calculating node centralities of a graph until a designated number of central nodes are detected. A percentage of the central nodes are then selected as pivot nodes. The neighboring nodes to each of the pivot nodes are then collapsed until the graph shrinks to a predefined threshold of total nodes. Responsive to the number of total nodes reaching the predefined threshold, the simplified graph is outputted.

1. A computer system, comprising:
a memory having computer readable computer instructions; and a processor for executing the computer readable instructions to perform a method comprising: calculating node centralities of a graph until a designated number of central nodes are detected; selecting a percentage of the central nodes as pivot nodes; collapsing neighboring nodes to each pivot node until the graph shrinks to a predefined threshold of total nodes; and outputting the graph responsive to reaching the predefined threshold.
