With the standardization of SKOS 1 (Simple Knowledge Organization System) in August 2009 a data model has been offered to publish controlled vocabularies and taxonomies on the web in a technical and semantically interoperable way. The heterogeneous environment of various vocabularies worldwide can be technically harmonized prospectively and especially the content of traditional databases can be...

The heterogeneous environment of information retrieval on the World Wide Web has brought the recognition for the need of interoperability among diverse systems to the fore. In subject retrieval, users encounter not only different vocabularies and schemes but also different languages. As a result, there has been a flourish of projects in the last few years aimed at improving the interoperability...

The Unified Medical Language System (UMLS) is a terminology integration system developed and maintained by the U.S. National Library of Medicine (NLM). Over the past 20 years, the UMLS Metathesaurus has been extended to encompass 168 source vocabularies. While English is the dominant language (116 source vocabularies), 52 vocabularies in the Metathesaurus are in languages other than English (6 ...

Creating, documenting, publishing and maintaining an RDF Schema vocabulary is a complex, time-consuming task. This makes vocabulary maintainers reluctant to evolve their creations quickly in response to user feedback; it prevents use of RDF for casual, ad-hoc data publication about niche topics; it leads to poorly documented vocabularies, and contributes to poor compliance of vocabularies with ...

This paper describes our tools and method for an evaluation of the practical and logical implications of combining common linked data vocabularies into a single local logical model for the purpose of reasoning or performing quality evaluations. These vocabularies need to be unified to form a combined model because they reference or reuse terms from other linked data vocabularies and thus the de...

In typical development, word learning goes from slow and laborious to fast and seemingly effortless. Typically developing 2-year-olds are so skilled at learning noun categories that they seem to intuit the whole range of things in the category from hearing a single instance named – they are biased learners. This is not the case for children below the 20th percentile on productive vocabulary (la...

The German Federal Ministry for Education and Research funded a major terminology mapping initiative at the GESIS Social Science Information Centre (GESIS-IZ), which found its conclusion in 2007. The task of this terminology mapping initiative was to organize, create and manage ‘cross-concordances’ between controlled vocabularies (thesauri, classification systems, subject heading lists) centred...
