WHY SKOS-XL?Use Cases for Taxonomies

based on SKOS Core + SKOS-XL

SKOS is used for taxonomy management in many different industries

▸ SKOS CoreWith SKOS Core, only concepts can be used as resources; labels are only ‘attached’ to concepts and cannot be described in more detail or related to each other

United States dollar

With SKOS-XL, labels can become resources

▸ SKOS-XL - the main addition to SKOS CoreWith SKOS-XL, each label can become a resource.

Use Cases for SKOS-XL

▸ Introduce attributes for labelsWith SKOS-XL, each label can have specific attributes, e.g. ‘isSymbol’ or ‘isISOcode’, etc.6

▸ Multiple and consistent (re)usage of labelsWith SKOS-XL, each label can be (re)used at multiple points of a thesaurus. This helps to keep a taxonomy even more consistent while labels are used in various contexts.

I need support to continuously extend our taxonomy / controlled vocabulary!

Create reference text corpus ...

… calculate statistics incl. co-occurences about concepts, terms and phrases ...

… align thesaurus with reference corpus ...

… fetch candidate concepts from single documents ...

… fetch candidate concepts from extracted term list ...

… display co-occurences per candidate concept

and use them as synonyms ...

… display co-occurences per candidate concept

and use them as synonyms ...

… create new candidate concepts from co-occurences ...

… and relate them with other candidate concepts

… assert candidate concept into your thesaurus hierarchy ...

… and be ready to integrate the candidate concept into your thesaurus ...

… also related candidate concepts and subconcepts will be integrated ...

… et voilà - your thesaurus just got extended by some valuable new concepts ...

… for example, to use it as an additional facet in your semantic search application ...
