Action tendency analysis method and action tendency analysis device

摘要

PROBLEM TO BE SOLVED: To provide a behavior tendency analysis method and a behavior tendency analysis device capable of analyzing a tendency of behaviors caused by people regarding a service in consideration of a change (transition) of a state related to service usage. SOLUTION: In a behavior tendency analysis method for analyzing a tendency of a behavior of a target person with respect to a service provided by a service provider, a plurality of variables set regarding the content of the behavior of the target person are set at a plurality of time points in a target period. The time-series data shown for each is acquired for each subject, and the time-series data obtained for each subject is analyzed by a probabilistic language model to classify each subject into one of a plurality of state categories. Together with the initial probability of belonging to each state segment at the initial point in the target period, the transition probability between state segments, and the output probability for each of the multiple patterns that can be taken by multiple variables under each state segment, , Are calculated for each state classification.
