Extraction of Vocational Aptitude from Operation Logs in Virtual Space

Though vocational aptitude tests have been conducted, it sometimes judge people do not have aptitude for their desired jobs, because of weak points. If they know their weak points in early age such as elementary school ages, they may be able to overcome the points. It would extend their range of job choices. However, elementary school children cannot take most of tests because of loaf of knowledge. In this paper, we propose a method to evaluate vocational aptitudes for elementary school children quantitatively. In this method, we extract aptitude value, applying evaluation expression on operation logs. Specific evaluation expression is provided for every aptitude. We implemented aptitude test system assuming an example of the home-delivery service job experience. We have applied the system to 15 people.We have evaluated with correlation coefficient between extracted values and the result of CPS-J,Which is one of widely used vocational aptitude tests. From the result, we have found that some aptitudes should be calculated in early set while others can be derived from any set in repeated job experiences.
