  7. Differentiated in interoperability Conceptual Exploration „TREE“ Semantic interoperability Retrieval Paradigms Conceptual interoperability Conceptual Query Word-based interoperability Word-based Query jessica.hubrich@fh-koeln.de 2 Cologne July 19, 2010 jessica.hubrich@fh-koeln.de 7 Cologne July 19, 2010

  8. „TREE“ Word-based Interoperability Word-based Query • Level based on • Strings as access points Mapping method: automatic pattern matching Interoperability based on the formal representation of concepts, mainly main headings and not synonyms Reference points: Strings of main headings as they are stored in concept schemes Strings of main headings that are assigned to documents as part of the topical description Consideration of the relational structure jessica.hubrich@fh-koeln.de 2 Cologne July 19, 2010 jessica.hubrich@fh-koeln.de 8 Cologne July 19, 2010

  9. „TREE“ Word-based Interoperability Word-based Query • Level based on • Strings as access point Unspecified one-to-one-mappings which are not directed and primarily used for automatic search expansion Useful enhanced access points which lack precision; enhanced access reduced to word-based queries Conceptual queries limited to concepts of the knowledge organization system No additional support for explorative processes jessica.hubrich@fh-koeln.de 2 Cologne July 19, 2010 jessica.hubrich@fh-koeln.de 9 Cologne July 19, 2010

  10. Conceptual Query Conceptual Interoperability • Level based on • Concepts as access point Mapping method: intellectual Interoperability based on concepts as they are stored in the indexing language with consideration of their a priori relations jessica.hubrich@fh-koeln.de 2 Cologne July 19, 2010 jessica.hubrich@fh-koeln.de 10 Cologne July 19, 2010

  11. Conceptual Query Conceptual Interoperability • Level based on • Concepts as access point Directed One-to-one or one-to-many mappings (bidirectional, unidirectional) Precise enhanced access points to support conceptual queries Possibly advanced support of processes of knowledge exploration in respect to a single concept scheme jessica.hubrich@fh-koeln.de 2 Cologne July 19, 2010 jessica.hubrich@fh-koeln.de 11 Cologne July 19, 2010

  17. Conceptual Exploration Differentiated Interoperability • Concepts (controlled headings and their synonyms) as access points • A priori relations to support processes of knowledge exploration Mapping method: intellectual Prerequisite: Conceptual interoperability Differentiated intersystem relations !the more expressivity of intersystem relations, the more functionality! CrissCross intersystem relations adjusted to the undirectional mapping approach and the characteristics of the connected indexing languages (SWD,DDC), primarily for ranking mechanisms versioning of the mapping relation by adding a time stamp to the mapping to guarantee precise transition over time even when the meaning of concepts have changed or concepts have been relocated and hence the relation has changed jessica.hubrich@fh-koeln.de 2 Cologne July 19, 2010 jessica.hubrich@fh-koeln.de 17 Cologne July 19, 2010

  18. Conceptual Exploration Differentiated Interoperability • Concepts (controlled headings and their synonyms) as access points • A priori relations to support processes of knowledge exploration SKOS mapping types as mirror of common (bidirectional) thesauri relationships with assigned logical properties to draw inferences MappingRelations ExactMatch: symmetric, transitive – concepts can be used interchangeably CloseMatch: symmetric – interchangeability in some information retrieval applications BroadMatch: inverse to NarrowMatch(and vice versa)– hierarchical mapping link RelatedMatch: symmetric – associative mapping link Problem: In order to be able to draw inferences, the structures of the connected indexing language have to be considered together with the mapping relations to guarantee a consistent formal logic relational structure – but many concept schemes do not have such a structure jessica.hubrich@fh-koeln.de 2 Cologne July 19, 2010 jessica.hubrich@fh-koeln.de 18 Cologne July 19, 2010

  19. Conceptual Exploration Differentiated Interoperability • Concepts (controlled headings and their synonyms) as access points • A priori relations to support processes of knowledge exploration Differentiated intersystem relations primarily promote a precise transition from one concept scheme to another; structural and typological differences are still a problem Additional support for extensive explorative processes can be provided by adjustment of concept schemes with means of internationalization and localization Internationalization Process of generalizing / delocalizing a KOS with reference to the representation of concepts and their semantic relations so that it can handle multiple languages and viewpoints Localization Process of modifying KOS in regard to the local information needs. It involves the adequate translation of the internationalized concepts into the specific language as well as the enhancement and elaboration of local / national concepts and semantic relations in a local KOS jessica.hubrich@fh-koeln.de 2 Cologne July 19, 2010 jessica.hubrich@fh-koeln.de 19 Cologne July 19, 2010
