Service-oriented Context-aware Framework

Abstract

Location- and context-aware services are emerging technologies in mobile and desktop environments, however, most of them are difficult to use and do not seem to be beneficial enough. Our research focuses on designing and creating a service-oriented framework that helps location- and context-aware, client-service type application development and use. Location information is combined with other contexts such as the users' history, preferences and disabilities. The framework also handles the spatial model of the environment (e.g. map of a room or a building) as a context. The framework is built on a semantic backend where the ontologies are represented using the OWL description language. The use of ontologies enables the framework to run inference tasks and to easily adapt to new context types. The framework contains a compatibility layer for positioning devices, which hides the technical differences of positioning technologies and enables the combination of location data of various sources

Hybrid Aspect of Context-Aware Middleware for Pervasive Smart Environment: A Review

“…Considering an example to illustrate how a same service works differently in diverse domain applications, consider the tracking as a service and it is applied in different domain applications, such as in the following: (i) In Scenario 1, an application of the transport system, location is tracked using GPS or some other techniques. Here, location is the context, and GPS is a device used to trace the location [33]. (ii) In Scenario 2, an application of hospital, location of the doctor, patient, and object can be traced using RFID tag.…”

Towards a Context-Aware Framework for Improving Collaboration of Users in Groupware Systems

“…[12,13,38,39]), and (c) frameworks (e.g. [19][20][21]36]). All the aforementioned works are important because they identify variables of collaboration and context awareness to support users to conduct their collaborative activities more efficiently.…”
