Abstract
Both of mobile multimedia and mobile Internet are the important development directions of the mobile service. However, it would take great cost by using the high data transmission rate of wireless multimedia communication service. Under the premise of not increasing the investment in hardware, the personalized service could be applied to the mobile service to not only reducing wireless multimedia communication cost but also keeping the quality of mobile service for users. This paper presents a modeling method of mobile phone user profile based on Ontology. This paper founds a model in a method of spatial graph and introduces the theory of interval valued fuzzy sets, brings forward a series of correlative definitions and formulae of founding the model and designs an Algorithm on the Spatial Graph’s Establishment and Updating. Then, it also studies the reasoning technology based on the mobile phone user profile and presents a Reasoning Algorithm on the Mobile Phone User Profile. It should be considered that we have made a useful attempt on the study of founding user profile and forecasting users’ possible requirements.
