Action pattern analysis device, action pattern analysis method, and action pattern analysis program

摘要

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.

1. An action pattern analysis device comprising:
hardware including a processor; a stay point cluster extraction unit, implemented at least by the hardware, for clustering position information logs containing a user's measurement position and measurement time thereby to extract a stay point where the user stays; a non-stay point position information log extraction unit, implemented at least by the hardware, for extracting a set of position information logs from which a position information log extracted as the stay point is removed; a moving path cluster extraction unit, implemented at least by the hardware, for clustering the extracted set of position information logs plotted in a multidimensional space defined by numerical information indicating the measurement position and a time based on a Euclidean distance on the multidimensional space thereby to extract a user's moving path; and a position information plot unit, implemented at least by the hardware, for plotting a position information log containing the user's measurement position and the measurement time on the multidimensional space defined by the numerical information indicating the measurement position and the time, wherein the moving path cluster extraction unit weights the extracted set of position information logs by applying a first weight to the Euclidean distance in a time direction in a position information space defined by numerical information indicating the measurement position on the multidimensional space, and clusters the position information logs weighted by applying the first weight, wherein the position information plot unit plots a position information log containing values indicating latitude and longitude as a user's measurement position on a 3D space defined by latitude, longitude and time, wherein the stay point cluster extraction unit weights the position information log by applying a second weight to the Euclidean distance in the time direction relative to a latitude/longitude plan defined by latitude and longitude in the 3D space, and wherein the moving path cluster extraction unit weights the extracted set of position information logs by applying the first weight to the Euclidean distance in the time direction relative to the latitude/longitude plan defined by latitude and longitude in the 3D space.
