<P>PROBLEM TO BE SOLVED: To generate a correlation diagram by which correlation among persons and time changes in the strength of relationship can be easily grasped. <P>SOLUTION: An information processing apparatus includes a correlation visualization part for generating a correlation diagram obtained by setting one optional person in a data group as a reference person and visualizing correlation among correlated persons correlated to the reference person and the reference person and time changes of the correlation by using relationship information indicating relationship among persons calculated based on the data group to be a set of data including information regarding time and friendship degree information indicating a degree of friendship among persons. The correlation visualization part extracts one or more correlated persons from the data group based on the relationship information, determines a separation distance between a node expressing the reference person and a node expressing each correlated person at each point of time in time series in accordance with the friendship degree information and determines arrangement of nodes expressing correlated persons while considering correlation of the same person between adjacent points of time in the time series. <P>COPYRIGHT: (C)2013,JPO&INPIT |
