  1. SKOS-2-HIVE UNT workshop

  2. Morning Session Schedule Introductions and Exploring HIVE Section 1: Knowledge Organization and Vocabulary Control Section 2: From Thesauri to SKOS BREAK Section 3: From SKOS to HIVE Section 4: Evaluating HIVE

  3. Introductions Hollie White hcwhite1@email.unc.edu

  4. Exploring HIVE http://hive.nescent.org

  5. Section 1: Knowledge Organization andVocabulary Control

  6. Greenberg’s Ontology Continuum Classical view of ILS languages <___|____|_______|______|_____|______|______|_______|________|_____> Simple thesauri/ deeper taxonomies low level full/intricate Key word CV thesauri ontologies ontologies Lists (WordNet)(OWL)

  7. Types of Vocabulary Control From least to most structure • Term lists Controlled but semi-unstructured list Example: ASU portal-- http://library.lib.asu.edu/search/y • Controlled Vocabulary Less structured thesauri also referred to as subject heading lists Example: MeSH -- http://www.nlm.nih.gov/mesh/MBrowser.html • Thesauri Composed of indexing terms/descriptors Example: NASA -- http://www.sti.nasa.gov/thesfrm1.htm

  8. Types of Vocabulary Control continued • Taxonomy A subject-based classification that arranges the terms in the controlled vocabulary into a hierarchy (Garshol 2004) Example: ITIS--http://www.itis.gov/ (search Abutilon menziesii) • Ontology A way to convey or represent a class (or classes) of things, and relationships among the classes. Example: Gene Ontology--http://www.geneontology.org/

  9. KOS used in Digital Libraries Looked at 269 online digital libraries and collections KOS used: Locally developed taxonomy (113) LCSH (78) Author list (34) Thesauri (26) Alphabetical listing (20) Geographic arrangement (16) Shiri, A. and Chase-Kruszewski, S. (2009) Knowledge organization systems in North American digital library collections. Program:electronic library and information systems. 43 (2) pp 121-139.

  10. Discussion: Think about your own organization. What type of controlled vocabularies, thesauri, and ontologies does your organization use for everyday work? How do these vocabulary choices help you meet the goals of your institution? See activity page

  11. Section 2: From Thesauri to SKOS

  12. Simple Knowledge Organization Systems Classical view of ILS languages <___|____|_______|______|_____|______|______|_______|_______|______> Simple thesauri/ deeper taxonomies low level full/intricate Key word CV thesauri ontologies ontologies Lists (i.e WordNet) (i.e. OWL) SKOS

  13. Common thesaural identifiers • SN Scope Note Instruction, e.g. don’t invert phrases • USE Use (another term in preference to this one) • UF Used For • BT Broader Term • NT Narrower Term • RT Related Term

  14. Syndetic Relationships Syndetic relationships are the conceptual connections between terms. Three types of syndetic relationships • Hierarchical • Equivalent • Associative

  15. Hierarchical • Level of generality – both preferred terms • BT (broader term) • Birthday cakes BT Cakes • NT (narrower term) • Cakes NT Birthday cakes …remember inheritance

  16. Equivalent • When two or more terms represent the same concept • One is the preferred term (descriptor), where all the information is collected • The other is the non-preferred and helps the user to find the appropriate term

  17. Equivalent • Non-preferred term USE Preferred term • Biological diversification USE Biodiversity • Preferred term UF (used for) Non-preferred term • Biodiversity UF Biological diversification

  18. Associative • One preferred term is related to another preferred term • Non-hierarchical • “See also” function • In any large thesaurus, a significant number of terms will mean similar things or cover related areas, without necessarily being synonyms or fitting into a defined hierarchy

  19. Associative • Related Terms (RT) can be used to show these links within the thesaurus • Bed RT Bedding • Paint Brushes RT Painting • Vandalism RT Hostility • Programming RT Software

  20. Identifiers to SKOS code • SN Scope Note = skos:scopeNote • USE Use = skos:prefLabel • UF Used For = skos:altLabel • BT Broader Term = skos:broader • NT Narrower Term = skos:narrower • RT Related Term = skos:related Each entry term has a skos:concept

  21. Terms vs. Concepts?Example: Table • Lexical level : Table • Conceptual level :

  22. What is a SKOS Concept? Zygotes BT Ova NT Oocysts RT Hemizygosity RT Reproduction RT Zygosity UF Ookinetes All these relationships make up a SKOS concept

  23. ConceptualizingSKOS See activity in packet

  24. Example 1:Web view of NBII entry

  25. XML Extensible Markup Language --Created by the World Wide Web Consortium (W3C). --Used to mark up documents on the internet or electronic documents. --Users get to describe the tags that are used and define how they are used.

  26. XML encoding

  27. NBII in XML <CONCEPT> <DESCRIPTOR>Desert plants</DESCRIPTOR> <BT>Desert organisms</BT> <BT>Plants</BT> <NT>Succulents</NT> <SC>ORIG Original</SC> <STA>Approved</STA> <TYP>Descriptor</TYP> <INP>2007-08-14</INP> <UPD>2007-08-14</UPD> </CONCEPT>

  28. CreatingSKOS/XML See activity online

  29. RDF Resource Description Framework “is a family of World Wide Web Consortium (W3C) specifications originally designed as a metadatadata model. It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax formats” --from Wikipedia

  30. RDF data model  is similar to Entity-Relationship or Class diagrams, statements about resource in subject-predicate- object expressions called “triples”. subject = resource predicate = traits or aspects of the resource and expresses a relationship between the subject and the object. http://www.w3.org/TR/rdf-concepts/

  31. The sky has the color blue RDF triple: a subject denoting "the sky“ a predicate denoting "has the color” an object denoting "blue”

  32. Things to know about RDF • Everything can be identified by URI’s • Resources and links can have types • Partial information is tolerated • There is no need for absolute truth • Evolution is supported • Minimalist design http://www.w3.org/2001/12/semweb-fin/w3csw

  33. Example of RDF <rdf:RDF xmlns:rdf=“http://www.w3.org/1999/02/22-rdf-syntax-ns#” xmlns:dc="http://purl.org/dc/elements/1.1/"> <rdf:Description rdf:about="http://hive.nescent.org/">       <dc:title>HIVE Web Interface</dc:title>  </rdf:Description> </rdf>
