SWebB: Semantic Web Browsing

In this talk I will present a browser, called SWebB (Semantic Web Browser), which explicitly uses, whenever available, the semantic information codified in Contextual Ontologies. Contextual Ontologies are ontologies enriched with Context Links. Ontologies define the conceptual model of a peer and describe its content. Context mappings are sets of bridge rules, namely pairs which allow to relate, via appropriate semantic relations (e.g., equivalence), concepts, roles and individuals in different ontologies. Using SWebB, context mappings, similarly to standard Web links, can be discovered, navigated, copied, and so on. Contexts mappings are discovered by Semantic Matching. Contextual Ontologies are formalized using the C-OWL Language. The talk will also provide an overview of the key aspects of C-OWL.
