METHOD, DEVICE, AND COMPUTER PROGRAM FOR VISUALIZING RISK ASSESSMENT VALUATION OF SEQUENCE OF EVENTS

摘要

Provided are a method, a device, and a computer program which are capable of estimating a totally ordered set on the basis of partially ordered sets indicating sequences of events in order to visualize a risk assessment valuation which is calculated for each sequence of events. The present invention calculates and displays a risk assessment valuation for a sequence of events which is a partially ordered set chronologically indicating a portion of an event group, comprising M (M is a natural number) types of events, where M is finite. On the basis of the sequence of events, an M-dimensional sparse order matrix is generated in order to calculate a dense order matrix by interpolating the generated sparse order matrix. On the basis of the calculated dense order matrix, a mapping matrix, which maps a similarity relationship between sequences of events using an embedding technique in a two-dimensional space or a three-dimensional space, is calculated so that, using the calculated mapping matrix, corresponding points for each of the sequences of events upon the two-dimensional space or the three-dimensional space are calculated in order to display and output the calculated corresponding points in the two-dimensional space or the three-dimensional space.
