Abstract
A system state estimation apparatus to estimate a system state in a system that outputs log data upon executing a user action, the system state estimation apparatus includes a memory; and a processor configured to execute using log data accumulated in advance, to generate a stochastic model in which a system state and a user action are associated with log data when the user action is executed in the system state; and determining a user action that contributes to identification of the system state in the system, based on a probability distribution of the system state and the stochastic model.
