To understand the thoughts and behavior of a large group of people, surveys are often used to obtain objective data. They are generally composed of dozens of questions that can be quite timeconsuming, and a hassle to complete.

This paper applies data mining technology, which achieved the above-said outcome from performance evaluation results.
