Order evaluation system, order evaluation method, and program

Abstract

To allow a user to easily and intuitively grasp a cause when a node ranking is changed or when the user wants to know a basis of the ranking calculation.SOLUTION: The present invention is directed to an order evaluation system for evaluating ranking of nodes in a digraph formed of a plurality of nodes connected to one another. The system has matrix generating means for generating a transition probability matrix for use in defining probability of transition on a node based on the digraph, ranking calculating means for calculating a unique vector of the transition probability matrix generated by the matrix generating means with using a potential function to thereby calculate a ranking of the entire nodes, and ranking visualizing means for visualizing a state of the potential function corresponding to a predetermined node partially selected from the entire nodes based on the ranking of the entire nodes calculated by the ranking calculating means.SELECTED DRAWING: Figure 1
