Multimedia data has a rich and complex structure in terms of interand intra-document references. Its potential is severely limited unless effective methods for semantic extraction and semantic-based cross-media exploration and retrieval can be devised. Today’s leading-edge techniques in this area are working well for low-level feature extraction and, to a certain degree, for concept recognition...

The explication of the semantics of geospatial concepts is a crucial research priority which affects various aspects of information representation, formalization, integration, and exchange. The aim of the present paper is twofold. Firstly, it proposes a methodology for the semantic definition of geospatial concepts. The proposal is based on an analysis of the semantics of geospatial concepts de...

My core research interests are centered largely around semantic Web, services computing and the two stand out aspects of Web 2.0, which are: 1) Web as a platform and 2) Harnessing collective intelligence. Specifically, I am interested in modeling and representation, search and ranking, and integration aspects of services. Specific research areas include: • Representation of Web resources includ...

We present an application in the framework of semantic-enabled emarketplaces aimed at fully exploiting semantics of supply/demand descriptions in B2C and C2C e-marketplaces. Distinguishing aspects of the framework include logic-based explanation of query results, semantic ranking of matchmaking results, logic-based request refinement.

We explain how semantic interoperability is important for the Norwegian public sector. Important aspects for a technical solution are discussed. We choose UML to help us with our semantic interoperability efforts. Some of UML’s strong point and week point are considered. Our resulting TOR system is also described.

language users benefit from special phonetic tools in order to communicate linguistic information as well as different emotional aspects and paralinguistic information through daily conversation. having functions in conveying semantic information to listeners, prosodic features form the essential part of linguistic behavour, manipulating  them potentially can play an important role in transmitt...

Watson is a gateway to the Semantic Web: it collects, analyzes and gives access to ontologies and semantic data available online with the objective of supporting their dynamic exploitation by semantic applications. We report on the analysis of 25 500 ontologies and semantic documents collected by Watson, giving an account about the way semantic technologies are used to publish knowledge on the ...

This paper is to challenge the basic assumptions about ‘meaning’ in the current technologies for the Semantic Web including RDF(S). The contextual and communicative aspects should not be ignored in the use of language. In this paper, therefore, the intensional semantics of the Semantic Web is examined along with conceptualist semantics as an alternative framework.

The quality of information systems is a multidimensional concept. It covers several aspects including data quality. Anomalies in the data sources such as duplicates, similar and inconsistencies may be due to the poverty of their semantic descriptions. The use of ontologies to improve the semantic and the interoperability between systems should contribute to the improvement of quality.

Fragestellung des Projektes Semantics is a proper subdiscipline of linguistics with its on field or research, its own questions and its own methods. Semantic research is well established and we have a good (and continuously increasing) knowledge of semantic categories and semantic structures of natural language and languages. The project will extend current semantic analyses according to two as...
