PROBLEM TO BE SOLVED: To provide a POI estimation server which is capable of estimating a POI which a user interestedly views.SOLUTION: The POI estimation server includes: position and direction information storage means which stores position information and direction information of each information terminal; cluster information generation means which divides an information terminal group with which position information and direction information are individually associated, into a plurality of clusters on the basis of position information and generates, for each cluster, a cluster centroid position being an average of position information within the cluster and a cluster interest vector corresponding to the sum of direction information within the cluster; and POI determination means which determines, as a POI, an intersection between a first half line extending from the cluster centroid position of a first cluster of which the cluster interest vector has a maximum vector length, in the direction of the cluster interest vector and a second half line extending from the cluster centroid position of a second cluster of which the cluster interest vector has a second maximum vector length, in the direction of the cluster interest vector. |
