*OutlineObjective: Interoperability PlusKOS concept hubMethod: Knowledge-based, computer-assisted of canonical representations of conceptsResulting knowledge base and applications

*ObjectiveImprove semantic-based search of digital content across multiple collections in multiple languages.Interoperability between any two participating KOS (Knowledge Organization Systems) Support for search, esp. facet-based search for any collection indexed by a participating KOSfor free-text searchAssistance in cataloging (metadata creation) by catalogers or users (social tagging)Long-range goal: Web service where a KOS can be uploaded and mappings to specified target KOS are returned

*KOS Concept HubThe backbone of the proposed system is a faceted core classification of atomic concepts together with a set of relationshipsInteroperability is achieved by expressing concepts from all participating KOS as a canonical representation: description logic formula using atomic concepts and relationshipsMapping from KOS to KOS is achieved by reasoning over these canonical representations

*Method: How to get DL formulasKey: Efficient creation of canonical representations (DL formulas) Apply existing knowledge: Large knowledge base less effort for processing a new KOSUse knowledge of KOS structure for hierarchical inheritanceUse linguistic analysis of terms and captions Eliminate redundant atomic conceptsCheck or produce mapping results from assignment of concepts to the same recordsGet human editors input and verification where needed through a user-friendly interfaceKOS owners may verify and edit data pertaining to their KOS

*Knowledge baseRequires an ever larger classification and lexical knowledge base containing many kinds of data:A faceted classification of atomic concepts Seeded from sources with well-developed facets such as the AOD Thesaurus, the Harvard Business Thesaurus, the Art and Architecture Thesaurus, various ontologiesLinguistic knowledge bases such as Wordnet and mono-,bi-, and multi-langual dictionaries and thesauriMany KOS (Knowledge Organization Systems), such as LCC, DDC, DMOZ directory, LCSH, Gene Ontology, SchlagwortnormdateiThese will over time be fused into one large multilingual knowledge base with many terminological and translation relationships and relationships linking terms to concepts, with an increasing number of concepts semantically represented by a DL formula.

*Distributed implementationA KOS on the Web could assign DL formulas to its concepts let's call this a semantically enhanced KOS or SEKOSCould use any of a number of faceted core classifications or even several (using a unique URI for each elemental concept)Core classifications could be mapped to each otherIt is now a simple matter to map from any SEKOS to any other (somewhat dependent on the core classifications used)

*Take-home messageSemantics gives powerful systemsSemantik schafft maechtige Systeme

*This project will achieve the followingInteroperability between any two participating Knowledge Organization Systems (KOS) (to the extent the two schemes allow)Facet-based search for any collection indexed by a participating KOSfor free-text searchAssistance in cataloging (metadata creation) by catalogers or users (social tagging)Long-range goal: Web service where a KOS can be uploaded and mappings to specified target KOS are returnedMeansCreate a comprehensive knowledge base relating many classification schemes and subject heading lists used in libraries and in other contexts (LCC, DDC, DMOZ directory, LCSH, European schemes).Use combinations of atomic concepts taken from a well-structured underlying faceted classification to represent the meaning of classes and subject headings.
