Movement flow aggregation device, method, and program

Abstract

An extraction unit (21) extracts, from a plurality of pieces of flow information indicating transitions of actions or states of respective users, a common page transition pattern for each of a completed flow which has reached an action or state indicating completion and a quit flow which has been quit without reaching the action or state indicating completion. A conversion unit (22) creates, from patterns of respective users, a matrix including occurrence or nonoccurrence for each of the patterns and converts, by dimensional compression, the matrix into a latent variable for each user. A creation unit (25) creates, on the basis of the latent variable for each user, a decision tree for classification between the completed flow and the quit flow. A visualization unit (29) visualizes information pertaining to classification between the completed flow and the quit flow on the basis of the decision tree.
