Abstract
A position information plot means 81 plots a position information log containing a user'"'"'s measurement position and measurement date/time on a multidimensional space defined by numerical information indicating the measurement position and a time. A slay point cluster extraction means 82 weights the position information log so that a Euclidean distance in a time direction relative to a position information space is easily determined as short, and clusters the weighted position information logs thereby to extract a stay point where the user frequently stays. A moving path cluster extraction means 84 weights a position information log at a non-stay point so that a Euclidean distance in a time direction relative to a position information space is easily determined as long, and clusters the weighted position information logs thereby to extract a user'"'"'s moving path.

19. An action pattern analysis device comprising
a moving vector function value calculation unit for calculating a time different in measurement time contained in position information logs and a distance between measurement positions as differential values between the two adjacent position information logs sorted in an order of measurement time contained in the position information logs containing a user'"'"'s measurement position and measurement time; -
an attribute determination unit for determining, based on the time difference in measurement time and the distance between the measurement positions, whether an attribute of the position information log is a stay attribute indicating a stay point where the user frequently stays or a non-stay attribute indicating a non-stay point on a user'"'"'s moving path; a position information plot unit for plotting the position information log on a multidimensional space defined by numerical information indicating the measurement position and a time; a stay point cluster extraction unit for weighting the position information log so that a Euclidean distance in a time direction relative to a position information space defined by the numerical information indicating the measurement position in the multidimensional space is easily determined as short, and for clustering position information logs determined as having the stay attribute among the weighted position information logs thereby to extract the stay point; and a moving path cluster extraction unit for weighting the position information log so that a Euclidean distance in a time direction relative to the position information space is easily determined as long, and for clustering position information logs determined as having the non-stay attribute among the weighted position information logs thereby to extract a user'"'"'s moving path. - View Dependent Claims (20, 21)
