In dynamically and collaboratively building ontology system, the knowledge activities of users are the randomness, fuzziness and uncertainty, which could cause ontology quality uncertainty, it is urgent to establish a quality evaluation mechanism to control the quality of ontology. In this paper, based on analyzing the influence factors of ontology approved degree, an ontology approved degree model based on normal cloud model is put forward. In the model, normal cloud model was introduced to describe users' uncertainty knowledge activities on a triple and gain the corresponding weight; then an algorithm was discussed to compute ontology approved degree from the experts and common users and mat-lab was used to stimulate it.
