  • This is here kind of as a joke, being “one of those presentations that starts with a definition that everyone knows….” However, I think it also has some value to make the point that we are still talking about different ways to manage taxonomies, just two different methods.
  • This is here to express the idea of metadata that surrounds the term.
  • SKOS-XL vs. Traditional Term Based Taxonomy Management

    1. 1. Jim Sweeney Product Manager Synaptica, LLC SKOS-XL vs. Traditional Term Based Taxonomy Management
    2. 2. Taxonomy Defined tax·on·o·my /takˈsän mē/ ə Noun The branch of science concerned with classification; systematics. The classification of something: "the taxonomy of these fossils".
    3. 3. Traditional Term Based Mgt. • Each Term represents the meaning of the “concept”, which may result in a degree of subjectivity. • Each “concept” may be represented independently by Terms in multiple languages. • Each Term may be associated with a set of metadata records to offer further context and which may differ in each language.

    5. 5. Term Metadata Values Dog: Definition: A domesticated carnivorous mammal that typically has a long snout, an acute sense of smell, and a barking, howling, or whining voice. Scientific Name: Canis lupus familiaris Editorial Notes: Term added 1/1/2011. Term updated 4/4/2012. Language: English
    6. 6. Introducing SKOS (Simple Knowledge Organization System) • Developed and refined by W3C working group from 2006 to 2008 • Recommendation Published in 2009 • “SKOS is an area of work developing specifications and standards to support the use of knowledge organization systems (KOS) such as thesauri, classification schemes, subject heading systems and taxonomies within the framework of the Semantic Web.” SKOS definition taken from: http://www.w3.org/2004/02/skos/intro
    7. 7. SKOS “Concepts” • One of the fundamental differences between traditional term based taxonomy management and SKOS is that the “concept” itself is abstract and meaning for it is derived from a collection of independent “labels” equally; not from any one term that defines a singular idea as in Term Based management. • Where term based management might be considered more one-dimensional in its approach, SKOS could be considered multidimensional in assigning meaning.

SKOS Collection English Preferred Label: Mammals English Preferred Label: Cats French Preferred Label: Chats Spanish Preferred Label: Gatos English Preferred Label: Dogs French Preferred Label: Chiens Spanish Preferred Label: Perros German Preferred Label: Hunde English Alternate Label: Mutts French Alternate Label: Clebs English Preferred Label: Terriers English Preferred Label: Sheepdogs
    9. 9. SKOS-XL (eXtension for Labels) • In 2009 a recommendation was made to expand SKOS to accommodate metadata for labels. • This allows for notes and other detailed information to be associated with preferred, alternate, and hidden label entries. • In addition, URIs (Uniform Resource Identifier) may be used to identify Concepts and Labels such that they may be used in other Controlled Vocabularies.
    10. 10. SKOS-XL Concept / Label Mgmt. Concepts may be managed in association with their preferred, alternate, and hidden labels.
    11. 11. SKOS-XL Concept / Label Mgmt. Concept details are displayed and editable as associated with the specified language. Information and ID’s are for concepts and not the assigned labels.
    12. 12. SKOS-XL Concept / Label Mgmt. Preferred, Alternate (Synonyms), and Hidden labels are managed independently through label management screens.
    13. 13. SKOS-XL Concept / Label Mgmt. Concept and label attributes are also managed independently.
    14. 14. SKOS-XL Concept / Label Mgmt. Finally, all related concepts are available for review and edit, again displayed in the language selected.
    15. 15. Conclusions and Questions • SKOS-XL presents a versatile method to represent controlled vocabularies through the use of independent Concept and Label definitions. • This method does also present challenges in learning a new way of understanding how meaning is assigned to a “concept”. • Is SKOS-XL appropriate and/or necessary for your organization’s approach to knowledge management?
