【 摘 要 】

In mobile geoinformation services, most intelligent systems ignore the users’ states and roles and only include the user's location. However, different user profiles need customized visualization styles in order to provide relevant spatial data. With the availability of a variety of data sources and the ability for continuous data updates, the service is able to perceive and react to instant changes. The aim of this research is to describe contextual ontological model which provides visualization on mobile devices. Therefore, intelligent visualization explained in this study is defined by a complete semantic model of the Ontology Web Language – Description Logic (OWL-DL) and Semantic Web Rule Language (SWRL). Consequently, a mobile visualization service sensitive to the instant changes of the user’s situation has been proposed. Egocentric design of a map-based service has been tested on a scenario-based application of a mobile emulator.
