Service reputation is a key factor for services selection and services composition in Service Oriented AmI system, and the calculation of reputation in AmI system should fully reflect the feature of multi -rating fusion and rating's utility value dynamic attenuation mechanism. A good model is important for reputation computing. The paper proposes three models from different views. Conceptual data model gives the constitution of reputation using the UML class diagram; Conceptual layered. model.classifies the related conceptual which involve in the reputation computing into different layers; Computation model gives the core algorithms which are used to computing the reputation. These models provide a reference guide.for reputation'. computing in service-oriented AmI.
