However non-expert users need to manage their composed services in a way they can understand. Policy-based management promises the ability...
Routing of contextual information within ubiquitous computing environments is a key challenge that must be tackled for such environments to be successful. It is accepted that such routing systems need to cope with mobile and volatile sources and destinations of contextual information, and semantic-based publish subscribe systems have been proposed as a means to support this. However such systems typically...
With ontologies increasing in number and becoming more common place, there is an ever increasing need for tools and techniques to cope with diversity and heterogeneity. We believe that the interfaces to ontology management tools will need to be engineered to allow ordinary non technical people to be able to use them effectively. This paper reports upon a mapping process using the dasiataggingpsila...
The trends for pushing more operational intelligence towards network elements to achieve more context-aware and self-managing behavior often requires elements to gather network knowledge without necessarily binding explicitly to all of the potential sources of that knowledge. Though event-based publish-subscribe models allow efficient distribution of knowledge where the event types are known globally,...
