TITLE
The Semantic Facet of Ubiquitous Computing

ABSTRACT
Ubiquitous computing has an impact on future information provision as it rises context-awareness significantly. Information systems are thus more in the position to view the users within their actual ambience and provide information suitable for information needs that are intertwined with the situation they are actually experiencing. Context-aware information provision locates, for instance, a visitor within a museum or exhibition and delivers automatically information on objects exposed close to the visitor s location. Context can also be more abstract if it addresses a situation that is part of a conversation, a newspaper article, or TV news. This paper describes an interface layer for abstract facets in context-awareness that allow interoperability among complex and volatile populations of different data sources. They map these heterogeneous content sources into a unified information space. The marriage of semantic web technologies with text mining catches up with the critical element of automating the collection of content-relevant information and of the construction of a coherent context.
