Özet

Data submission and refreshment, e.g. sensors, continuously feed a distributed information system. The system has to interpret incoming data in order to get valuable information which comes from different sources. Mobile users need more adaptive visualized spatial data according to location, device, personal profile, intention etc. In a semantic approach, an ontological model provides an intelligent system which is capable of extracting implicit information from explicit one. In this paper, some spatial concepts and properties have been defined for mobile devices and their users so as to produce context-aware visualization. The aim of these mobile contextual ontologies is to obtain a semantic model which inferences some parameters for an appropriate visualization.
