A Novel Context Ontology to Facilitate Interoperation of Semantic Services in Environments with Wearable Devices

Abstract

Abstract. The LifeWear-Mobilized Lifestyle with Wearables (Lifewear) project attempts to create Ambient Intelligence (Ami) ecosystems by composing personalized services based on the user information, environmental conditions and reasoning outputs. Two of the most important benefits over traditional environments are 1) take advantage of wearable devices to get user information in a non-intrusive way and 2) integrate this information with other intelligent services and environmental sensors. This paper proposes a new ontology composed by the integration of users and services information, for semantically representing this information. Using an Enterprise Service Bus, this ontology is integrated in a semantic middleware to provide context-aware personalized and semantically annotated services, with discovery, composition and orchestration tasks. We show how these services support a real scenario proposed in the Lifewear project. IntroductionWearable devices are becoming more advanced, accurate and capable of sensing. To take full advantage of them is necessary to combine their information with the obtained from the context and the own user. The amount and heterogeneity of the information that comes into play means that architectures and data models must be equipped with the features necessary to develop applications increasingly customized to the user and facilitate interoperation and information sharing. The main concern has been to developed ontologies, middlewares and architectures to resolve problems related with ubiquitous computing, but, basically thinking in services provided to the web. With the advance of technology, new services based on the user information, environmental conditions and reasoning outputs are emerging in the context of Ambient Intelligence (Ami) ecosystems. Adding to these data a user
