Leave of absence prediction system, prediction rule learning device, prediction device, leave of absence prediction method, and computer-readable recording medium

A leave of absence prediction method comprising:

• generating a prediction rule regarding prediction of a likelihood of a leave of absence based on first attendance management information including a time-series factor concerning an employee and on information indicating presence or absence of the leave of absence concerning the employee relating to each piece of the first attendance management information, the likelihood of the leave of absence being a likelihood of one employee taking the leave of absence in a predetermined time;
• and
• predicting the likelihood of the employee as a target of prediction taking the leave of absence based on second attendance management information including a time-series factor with respect to an employee as the target of prediction and on the prediction rule.

A computer-readable recording medium storing a program causing a computer to execute:

• processing of generating a prediction rule concerning prediction of a likelihood of a leave of absence based on first attendance management information including a time-series factor concerning an employee and on information indicating presence or absence of the leave of absence concerning the employee relating to each item of the first attendance management information, the likelihood of the leave of absence being a likelihood of one employee taking the leave of absence in a predetermined time;
• and
• processing of predicting the likelihood of the employee as a target of prediction taking the leave of absence based on second attendance management information including a time-series factor with respect to an employee as the target of prediction and on the prediction rule.
