Uma infraestrutura de suporte a aplicações cientes de contexto com enfoque no usuário final.

Abstract

Context-aware applications have become popular as a consequence of the technological advances on mobile devices, sensors, and wireless network communication. However, there are many challenges in the development of these applications. For instance, which contextual information will be used, how to represent, capture, proccess and use the context in the system are some of such application development challenges. Frameworks and middlewares to improve context-aware application development have been proposed, but they still lack helping users in customizing their applications. Furthemore most proposed solutions do not have an extensible ontology-based context model and an efficient communication which enables to explore the main features of such approach. This work proposes an infrastructure to support context-aware applications, which uses an extensible ontology-based context model and communication through SPARQL and SPARQL Update. Also there are visual tools aiming to helpend-users in the creation and validation of context rules.
