From SKOS over SKOS-XL to Custom Ontologies
•
6 j'aime•3,530 vues
This slidedeck is about PoolParty Semantic Suite (http://www.poolparty.biz/), especially about features included by releases 5.2 and 5.3. See how taxonomy management based on SKOS can be extended with SKOS-XL, all based on W3C's Semantic Web standards. See how SKOS-XL can be combined with ontologies like FIBO. PoolParty's built in reference corpus analysis based on powerful text mining helps to continuously extend taxonomies. Its built-in co-occurence analysis supports taxonomists with the identification of candidate concepts. PoolParty Semantic Integrator can be used for deep data analytics tasks and semantic search. See how this can be integrated with various graph databases and search engines.

From SKOS over SKOS-XL to Custom Ontologies
- 1. Andreas Blumauer CEO, Semantic Web Company WEBINAR: PoolParty 5.3 From SKOS over SKOS-XL to Custom Ontologies 1
- 2. AGENDA ● Use Cases for Taxonomies based on SKOS Core + SKOS-XL ● Live Demo ● PoolParty’s Corpus Analysis incl. Co-occurences ● PoolParty Semantic Integrator - What’s new? ● Roadmap 2016 2
- 3. WHY SKOS-XL? Use Cases for Taxonomies based on SKOS Core + SKOS-XL 3
- 4. SKOS is used for taxonomy management in many different industries ▸ SKOS Core With 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 4 skos: Concept United States dollar skos:prefLabel USD US$ skos:altLabel skos: Concept skos:related United States of America skos:prefLabel USA skos:altLabel
- 5. With SKOS-XL, labels can become resources ▸ SKOS-XL - the main addition to SKOS Core With SKOS-XL, each label can become a resource. 5 skos: Concept USD US$ skos:altLabel skos: Concept skos:related United States of America skos:prefLabel USA skos:altLabel skos-xl: Label skos-xl:prefLabel United States dollar skos-xl:literalForm
- 6. Use Cases for SKOS-XL ▸ Introduce attributes for labels With SKOS-XL, each label can have specific attributes, e.g. ‘isSymbol’ or ‘isISOcode’, etc.6 skos: Concept United States dollar skos:prefLabel USD $ skos:altLabel skos-xl: Label skos: Concept skos-xl:prefLabel United States dollar skos-xl:literalForm skos-xl: Label skos-xl:altLabel USD skos-xl:literalForm true my:isISOcode skos-xl: Label skos-xl:altLabel $ skos-xl:literalForm truemy:isSymbol
- 7. Use Cases for SKOS-XL ▸ Put labels in a context With SKOS-XL, each label can have specific relations, e.g. information about provenance, etc.7 skos-xl: Label fibo-acc- cur: Currency skos-xl:prefLabel United States dollar skos-xl:literalForm skos-xl: Label skos-xl:altLabel USD skos-xl:literalForm fibo-plc- loc: Location fibo:isTenderIn United States of America skos:prefLabel skos-xl: Label skos-xl:altLabel Coco skos-xl:literalForm geo: Spatial Thing my:isNicknameIn Peru skos:prefLabel
- 8. Use Cases for SKOS-XL ▸ Relate labels to each other With SKOS-XL, each label can have specific relations, e.g. ‘isPredecessor’, ‘translates’, etc.8 skos-xl: Label fibo-plc- loc: Location skos-xl:prefLabel Switzerland@en skos-xl: Label Schweiz@de fibo-acc- cur: Currency fibo:isTenderIn Swiss franc skos:prefLabel skos-xl: Label Swiss Confederation@en skos-xl: Label Schweizerische Eidgenossenschaft@de skos-xl:altLabel my:translates my:translates
- 9. Use Cases for SKOS-XL ▸ Relate labels to each other With SKOS-XL, each label can have specific relations, e.g. ‘isPredecessor’, ‘translates’, etc.9 skos-xl: Label fibo-plc- loc: Location skos-xl:prefLabel Switzerland@en fibo-acc- cur: Currency fibo:isTenderIn Swiss franc skos:prefLabel skos-xl: Label Swiss Confederation@enskos-xl:altLabel my:isPredecessor
- 10. Use Cases for SKOS-XL ▸ Multiple and consistent (re)usage of labels With 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. 10 skos-xl: Label fibo-plc- loc: Location skos-xl:prefLabel Switzerland@en fibo-acc- cur: Currency fibo:isTenderIn Swiss franc skos:prefLabel skos-xl: Label Swiss Confederation@enskos-xl:altLabel my:isPredecessor geo: Spatial Thing skos-xl:prefLabel
