    • 1. Simple Knowledge Organization System (SKOS) <ul><li>Lynn Leitte, Sr. Content Strategist, Avenue A | Razorfish </li></ul><ul><li>May 16, 2008 </li></ul>
    • 2. Agenda <ul><li>Where did SKOS come from? </li></ul><ul><li>What’s it all about? </li></ul><ul><li>Under the hood </li></ul><ul><li>How can I use this? </li></ul><ul><li>Questions & Discussion </li></ul><ul><li>SKOS resources </li></ul>
    • 3. Where did SKOS come from? <ul><li>Knowledge Organization Systems (KOS) already exist in: </li></ul><ul><ul><li>Records Management practice (RM) </li></ul></ul><ul><ul><li>Content Management Systems (CMS) </li></ul></ul><ul><ul><li>Library & Information Science (LIS) practice </li></ul></ul><ul><ul><li>Knowledge Management practice (KM) </li></ul></ul><ul><li>Generally, those KOS are not semantic web enabling systems </li></ul>
    • 4. Where did SKOS come from? <ul><li>Originated with EU-SWAD </li></ul><ul><li>Transferred to W3C SWDWG </li></ul><ul><ul><li>Community driven input with gateway being w3C forums </li></ul></ul><ul><ul><ul><li>W3C member organizations can put participants into the SWDWG </li></ul></ul></ul><ul><ul><ul><li>Solicited input from actual vocabulary maintainers </li></ul></ul></ul><ul><ul><ul><li>Status is “working drafts” </li></ul></ul></ul>
    • 5. What’s it all about? <ul><li>Recognize that semantic technologies need a framework that provides lexical and conceptual understanding </li></ul><ul><li>Desire to improve search facilities & KOS re-use </li></ul><ul><ul><li>Concept based search instead of text based search </li></ul></ul><ul><ul><li>Re-use each others concept definitions </li></ul></ul><ul><ul><li>Relevant results in search across institution boundaries </li></ul></ul>
    • 6. What’s it all about? <ul><li>Capture the similarities across many traditional KOS </li></ul><ul><li>Make those similarities explicit </li></ul><ul><li>Create a standard and specification for the use of classification systems, thesauri, and other KOS </li></ul><ul><li>Enable a light weight, portable migration path </li></ul>What’s W3C trying to achieve with SKOS?
    • 7. Under the hood <ul><li>URI (reference) </li></ul><ul><li>SKOS vocabulary </li></ul><ul><li>RDF vocabulary </li></ul><ul><li>RDF graphs (diagrams) </li></ul><ul><li>Set of classes & properties to describe concept schemas </li></ul><ul><li>Extensible language </li></ul><ul><li>Counterpart of Web Ontology Language (OWL) </li></ul><ul><li>In short, it’s code & RDF graphs </li></ul>
    • 8. Under the hood <ul><ul><li>Basic structure: </li></ul></ul><ul><ul><li>skos:Concept </li></ul></ul><ul><ul><li>Lexical labeling: </li></ul></ul><ul><ul><li>skos:prefLabel </li></ul></ul><ul><ul><li>skos:altLabel </li></ul></ul><ul><ul><li>Semantic relations: </li></ul></ul><ul><ul><li>skos:broader </li></ul></ul><ul><ul><li>skos:narrower </li></ul></ul><ul><ul><li>skos:related </li></ul></ul>SKOS Core Vocabulary <ul><ul><li>Documentation: skos:definition </li></ul></ul><ul><ul><li>skos:note </li></ul></ul><ul><ul><li>skos:example </li></ul></ul><ul><ul><li>skos:scopeNote skos:historyNote </li></ul></ul>
    • 9. Under the hood Graph by Alistair Miles
    • 10. Under the hood Code by Corey A. Harper
    • 11. Why do I care about code? Isn’t that for developers <ul><li>You should care about what SKOS can enable in the user experience </li></ul><ul><li>It supports Semantic Web visions </li></ul>Under the hood
    • 12. <ul><li>“ Knowledge” has logical interrelationships and dependencies … </li></ul><ul><ul><li>e.g., if I am a Zoologist, I am also a Scientist </li></ul></ul><ul><ul><li>e.g., if Jenifer is my mother, then she is also one of my parents </li></ul></ul><ul><ul><li>e.g., if an animal eats only vegetation, then it is a herbivore </li></ul></ul><ul><ul><li>e.g., if Liz is my sister, and Holly is Liz’s daughter, then Holly is my niece </li></ul></ul>How can I use this?
    • 13. How can I use this? Facilitates a system having “knowledge” about the content it is presenting “ Where are pictures of my family members” cross application query Grandpa Grandfather Aunt Nephew Brother Sister Sibling Parent Mother Son SKOS can build the relations between concepts so that a system will “know” that a “sibling” and a “sister” are both relevant in a search for “family”.
    • 14. How can I use this? <ul><ul><li>“ We had a ball” comment in a social network entry </li></ul></ul>Context determines meaning SKOS helps solve ambiguation problems Did the author mean “fun”, “toy ball”, or “formal dance”
    • 15. How can I use this? <ul><ul><li>“ I need an allen wrench” is a consumer motivation for search </li></ul></ul><ul><ul><li>Store A labels them “allen wrench” </li></ul></ul><ul><ul><li>Store B labels them “hex key” </li></ul></ul><ul><ul><li>Store C labels them “zeta key” </li></ul></ul>Within repositories Across repositories <ul><ul><li>Brand A labels them “allen wrench” </li></ul></ul><ul><ul><li>Brand B labels them “hex key” </li></ul></ul>Supports concept-based search <ul><ul><li>With term-based search all results may not be returned. </li></ul></ul>
    • 16. How can I use this? <ul><li>With SKOS we are not talking about bringing ‘order’ to the entire web </li></ul><ul><li>SKOS can enable businesses or communities with a common interest to bringing order and understanding to a part of the web </li></ul>Important consideration
    • 17. How can I use this? <ul><li>GEMET - GEneral Multilingual Environmental Thesaurus </li></ul><ul><ul><li>Compilation of several multilingual vocabularies, and has been designed as a general thesaurus , </li></ul></ul><ul><ul><li>Define core general terminology for the environment. </li></ul></ul><ul><ul><li>The current version is available in 22 languages, and contains over 6,000 descriptors </li></ul></ul><ul><ul><li>http://www.eionet.europa.eu/gemet </li></ul></ul>Who else is using SKOS?

    • 19. How can I use this? <ul><li>SWED - Semantic Web Environmental Directory </li></ul><ul><ul><li>directory of environmental organizations and projects (UK based) </li></ul></ul><ul><ul><li>It is a proof of concept for creating a sustainable and scalable web-based system of Community Information Resources </li></ul></ul><ul><ul><li>Directory member organizations publish, own and control their own information. </li></ul></ul><ul><ul><ul><li>This information is then harvested and collated by SWED who produce a directory Web site </li></ul></ul></ul><ul><ul><li>www.swed.org.uk </li></ul></ul>Who else is using SKOS?
    • 20. SWED
