Abstract
A pervasive computing environment can be full of numerous embedded heterogeneous computing devices. This study proposes using ontology to enable effective communication and information sharing between devices to achieve invisible computing. Ontology provides a formal, explicit specification of a shared conceptualization of a domain. It facilitates knowledge sharing in open and dynamic distributed systems. Using ontology, devices can understand the messages without prior knowledge about the format or content of the messages. It also allows devices not originally designed to work together to interoperate. A global ontology for all applications and devices is impossible and inflexible for knowledge sharing in pervasive computing environments, and different ontologies for the same domain may require ontology mapping mechanisms to bridge their knowledge gaps. Because of limited memory, mobile and wearable devices embedded in the pervasive computing environment can only afford to store partial ontology that extracts the frequently used concepts defined in the ontology. This implies that only partial information is available, which makes traditional ontology mappings not suitable in the pervasive computing environment. This study proposes an online partial ontology mapping mechanism to meet the new
