Service-interaction descriptions: augmenting services with user interface modelsPresented as a shorter version of my EIS 2007 talk at Laboratoire d'Informatique Fondamentale de Lille (LIFL) in Lille on March 27th, 2008.AbstractSemantic service descriptions have paved the way for flexible interaction with services in a mobile computing environment. Services can be automatically discovered, invoked and even composed. On the contrary, the user interfaces for interacting with these services are often still designed by hand. This approach poses a serious threat to the overall flexibility of the system. To make the user interface design process scale, it should be automated as much as possible. We propose to augment service descriptions with high-level user interface models to support automatic user interface adaptation. Our method builds upon OWL-S, an ontology for Semantic Web Services, by connecting a collection of OWL-S services to a hierarchical task structure and selected presentation information. This allows end-users to interact with services on a variety of platforms. -
Semantic Web Technologies for HCIPresented during a HCI chit-chat session at our institute on September 8th, 2006.AbstractSemantic web technologies pop up frequently in current computer science research, in particular in fields related to HCI. Although the semantic web itself has not yet been fully realized, the supporting technologies are mature enough to be used for other applications.
The semantic web initiative centers around knowledge representation and automated reasoning about knowledge. This concept is general enough to find its use in many different fields (ambient intelligence, service oriented computing, etc.).
I will give an overview of the basic concepts of the semantic web. Important semantic web standards such as RDF, RDFS and OWL will be covered as well.
