Abstract

A text log feature vector generator generates a text log feature vector on the basis of a text log. A numerical log feature vector generator generates a numerical log feature vector on the basis of a numerical log. A system feature vector generator generates a system feature vector on the basis of the text log feature vector and the numerical log feature vector. A learning unit learns a plurality of appearance values of the system feature vector to generate a system state model as a model indicating a state of the system. A determination unit determines the state of the system at determination target time on the basis of the system feature vector at the determination target time and the system state model.
