SAGA reloaded: Towards a generic platform for developing cooperative applications

Web semântica e cérebro global juntos por uma boa causa

Nestes últimos anos, a investigação rumo a uma Web mais inteligente estava dividida em duas correntes: por um lado, a Web Semântica e seus agentes inteligentes e, por outro, o Cérebro Global e seus agentes inteligentes. No primeiro caso, o objectivo reside em desenvolver linguagens para que as máquinas possam entender o conteúdo dos documentos que armazenam. No segundo, a ênfase vai para a auto-organização da W...

A service-oriented middleware for composing context aware mobile services

Recent advances in wireless networks and mobile devices have brought about new scenes for the provision of services to end-users. Besides traditional services, new ones may be provided that transparently adjust and adapt to the user context. The user would have more choice and flexibility if, besides using the services, he could also compose his own services in an ad-hoc way. This paper presents iCas, an archit...

Composition of context aware mobile services using a semantic context model

Context-awareness has been regarded as an important feature for mobile services. However, only a few services are sensible to context and the features that are context-aware are still limited. Composition of Web services has received much interest in business-to-business or enterprise application, but not so much interest in business-to- consumer applications. This paper presents iCas, a novel architecture that...

Uma arquitectura para a composição dinâmica de serviços dependentes do contexto

A difusão das ligações sem fios nos locais de trabalho, de lazer e mesmo em casa, juntamente com a proliferação dos dispositivos móveis abrem novos cenários para o fornecimento de serviços aos utilizadores. Além dos serviços tradicionais de Internet devem por isso, ser disponibilizados novos serviços que de uma forma transparente se adeqúem e se adaptem ao contexto do utilizador. Os utilizadores teriam ainda ma...

Semantic web technologies in e-learning

The traditional view of learning puts most of the emphasis on face-to-face teaching and curriculum. It is very slow and expensive. Many people try to find e-Learning systems and learning objects on the Web. But that can be very difficult to find what we need with the actual search engines. How can someone fast and well in the Web? Our Proposal: Use Semantic Web technologies on the Development of virtual lear...
