This article presents the vision and results of creating basis for a national semantic Web content infrastructure in Finland 2003-2007. The main elements are shared open metadata schemas, core ontologies, public ontology services. Several practical applications testing demonstrating usefulness overviewed fields eculture, ehealth, egovernment, elearning, ecommerce.
Traditionally, the structure of controlled vocabularies used for annotation can be utilised reasoning information retrieval. However, this problematic when applied in Linked Data context. typically comes from different organisations and domains with mutually incompatible without explicit links between them resulting data silos. This paper argues that to solve problem one has transform into a Open Ontology cloud. We present method transforming set legacy thesauri cloud interlinked ontologies...
We present an approach to diversify entity search by utilizing semantics and inferred from the initial results. Our makes use of ontologies independent component analysis descriptions reveal direct latent semantic connections between entities in The are then used sample a set diverse entities. empirically demonstrate performance our through retrieval experiments that real-world dataset composed four databases. results indicate significantly improves both diversity effectiveness search.
