- Abstract
This paper proposed an indicators selection model that can be used when evaluator wants to ensure objective measurement and utilizes multivariate analysis invalidate but does not have enough data to support knowledge mining. The selection model is constructed based on the IRT theory. The Rasch model has been used to estimated ability characteristics of evaluators, combined with The three-parameter logic model to select indicators, unsuitable evaluators and indicators with ineffective evaluation factors were screened, the rest of indicators are closely related to evaluation object.
