Abstract
We took notice of the language which is one of the means of intention understanding.If evaluation criteria can be made with an easy linguistic expression, it will means that the design evaluation by various evaluators is attained. Then, we decided to build an evaluation index from the examination comment of each design prize. And we read a lot of examination comment and performed classification and arrangement. Then,We extract evaluation elements and evaluation indexs are expressed by the easy text. Since it was necessary to use evaluation indexs practically, the case study was carried out. And the problems of evaluation indexs were extracted in the case study, and the evaluation indexs have been improved.
