Context-awareness provisioning to support user-centric intelligence in Web of Object platform

摘要

Context-awareness plays an important role to offer an intelligence in terms of provision of user-centric features in Internet of Things (IoT). Web of Objects (WoO) has been introduced to support a framework to simplify application deployment, maintenance and operation of IoT service infrastructure by classifying and integrating objects on the World Wide Web. The semantic ontology is applied on a WoO platform to virtualize the physical objects and information, which expresses knowledge that provides intelligence to the user-centric service. The user-centric service is realized in terms of composite virtual object that can be formed by combining functionalities of multiple virtual objects and service rules. Context-aware service features can be provided in terms of self-awareness that helps in achieving autonomous behavior of the system. The paper proposes a WoO based context-aware architecture. To realize the context-aware user-centric service features, a conceptual semantic ontology model and a knowledge creation model have been discussed.
