Title: ANALYSIS DEVICE, ANALYSIS METHOD, AND ANALYSIS PROGRAM
Abstract:
A text log feature vector generation part (121) generates a text log feature vector on the basis of a text log. In addition, a numerical log feature vector generation part (122) generates a numerical log feature vector on the basis of a numerical log. Furthermore, a system feature vector generation part (123) generates a system feature vector on the basis of the text log feature vector and the numerical log feature vector. In addition, a learning part (124) generates, through learning of the values of the system feature vector in multiple instances, a system state model, that is, a model representing states of the system. In addition, a determination part (125) determines a state of the system at the time of making the determination on the basis of a system feature vector obtained at the time of making the determination and the system state model.
