Multidimensional Ontology Model to Support Context-aware Systems

Mobile computing is rapidly gaining importance because there is an incremental daily demand for information access from anywhere and at any time with multiple purposes. This situation gives rise to the new era of computing called Ubiquitous Computing, where it is necessary to develop new and improved structures for knowledge and information representation and exchange, in order to support the implementation of intelligent and context-aware systems. Thus search results will be fully based on contextual information and user profiles. This paper describes an architecture based on a multi-dimensional ontology model to represent mobile user contexts, Web services and application domains.
