Semanlink - Géographie AND Semantic Web

Very good presentation at WWW 2008. Nominated for the best paper award<br/>
Abstract: Applications of semantic technologies often require the representation of and reasoning with structured objects—that is, objects composed of parts connected in complex ways. Although OWL is a general and powerful language, its class descriptions and axioms cannot be used to describe arbitrarily connected structures. An OWL representation of structured objects can thus be underconstrained, which reduces the inferences that can be drawn and causes performance problems in reasoning. To address these problems, we extend OWL with description graphs, which allow for the description of structured objects in a simple and precise way. To represent conditional aspects of the domain, we also allow for SWRL-like rules over description graphs. Based on an observation about the nature of structured objects, we ensure decidability of our formalism. We also present a hypertableau-based decision procedure, which we implemented in the HermiT reasoner. To evaluate its performance, we have extracted description graphs from the GALEN and FMA ontologies, classified them successfully, and even detected a modeling error in GALEN.

DEMO of the STITCH project ("Semantic Interoperability To access Cultural Heritage")

Tags:

The STITCH DEMO webserver demonstrates the added value of semantical integration of multiple collections. 
<br/>
The collections that are linked by the prototype RDF Multi-Faceted-Search browser are the Rijksmuseum Masterpieces Collection (ARIA) and the Medieval Illuminated Manuscripts at the National Library of the Netherlands<br/>
SKOS is used to enable mixing/merging of separate vocabularies:
Cultural-heritage collections are typically indexed with metadata derived from a range of different vocabularies, such as AAT, Iconclass and in-house standards. This presents a problem when one wants to use multiple collections in an interoperable way. In general, it is unrealistic to assume unification of vocabularies. Vocabularies have been developed in many sub-domains, each with their own emphasis and scope. Still, there is significant overlap between the vocabularies used for indexing. The prime research objective of this subproject is to develop theory, methods and tools for allowing metadata interoperability through semantic links between the vocabularies.
