This paper establishes what makes an ontology different in Modeling and Simulation (M&S) from other disciplines, vis-a-vis, the necessity to capture a conceptual model of a system in an explicit, unambiguous, and machine readable form. Unlike other disciplines where ontologies are used, such as Information Systems and Medicine, ontologies in M&S do not depart from a set of requirements but...
In this paper we define an ontological model to accurately represent the context in Pervasive Computer Supported Collaborative Work. A major issue in this domain is the mass of information required to correctly depict a situation. As we need to represent users and devices according to multiple aspects (physical, computational, social ...) the amount of information can quickly become unmanageable....
The main idea of pervasive computing is to embed computer into the living environment or tool of human, so as to make the computer invisible from userpsilas sight and the users can focus on their task itself, instead of the computer. As having natural relationship with the spatial distribution and mobile, the pervasive computing has been applied in geospatial information areas widely. However, the...
In the paper, it refers to the concepts of ontology, OWL and context, different context information is defined by the tuple method, and establishes the model of context-awareness based on ontology in Smart-Home, and then it introduces the model of reasoning and memory in detail; and studies the affections of ontology on the two models. At last, the paper explains the application of model by using...
Changing system requirements, especially for context awareness (CA) systems, often cause modifications in the software systems in order to adapt to dynamic environments. Since the requirements may become temporarily obsolete or contrary to human intentions, the CA systems need to be tuned to resolve the conflict. On the other hand, most CA design methods rely on pre-defined requirements and reasoning...
Knowledge representation is a multidisciplinary subject that needs to apply theories and techniques from logic, ontology and computation. There are a great number of languages able to represent knowledge, among them UML can be considered a suitable language for modelling knowledge. It could be included within the category of visual languages for knowledge representation. On the other hand, numerous...
