  1. Controlled Vocabulary & Thesaurus Design Resources & Future Directions

  2. Thesaurus Design Software • Comprehensive list of Thesaurus Software • http://www.willpower.demon.co.uk/thessoft.htm • Comparison of Thesaurus Software • http://www.willpower.demon.co.uk/thestabl.htm Developed by the Association of Library Collections & Technical Services and Library of Congress’s Cataloger’s Learning Workshop

  3. A Cautionary Note • The true work of controlled vocabulary design is the collection and intellectual organization of terms! • Thesaurus software • A tool for developing thesauri • Analogous to the functionality of a word processor for writing a book • Unfortunately will not do all of the work for you • That said, it is always good to have the right tool for the job! Developed by the Association of Library Collections & Technical Services and Library of Congress’s Cataloger’s Learning Workshop

  15. The Future of Controlled Vocab • Integrated ILS and thesauri • The semantic web • Goals • Make semantic relationships machine-readable • Distributed database platform • Combined sets of semantic relationships = Semantic Web • Some XML based technologies • RDF - Resource Description Framework • OWL - Web Ontology Language • RSS - Really Simple Syndication • Ex. MARCXML Developed by the Association of Library Collections & Technical Services and Library of Congress’s Cataloger’s Learning Workshop

  16. Continuum of Vocabulary Control Taxonomy Ontology Synonym Ring Thesaurus List Less Complexity More Synonym Control Ambiguity Control Synonym Control Hierarchical Relationships Ambiguity Control Synonym Control Hierarchical Relationships Associative Relationships Ambiguity Control Developed by the Association of Library Collections & Technical Services and Library of Congress’s Cataloger’s Learning Workshop

  17. A Terminology Challenge Information Science Business Taxonomy Controlled Vocabulary Ontology Computer Science Developed by the Association of Library Collections & Technical Services and Library of Congress’s Cataloger’s Learning Workshop

  18. Changing Definitions • When the standard was published • Ontology ~ Taxonomy = Hierarchy • Now… • Taxonomy = Controlled Vocabulary = Ontology • Expect it to continue to change! Developed by the Association of Library Collections & Technical Services and Library of Congress’s Cataloger’s Learning Workshop

  19. Taxonomies are Everywhere • Especially in product websites • Examples include • Yahoo!, Amazon, HomeDepot, etc. • To see them you need to just look around Developed by the Association of Library Collections & Technical Services and Library of Congress’s Cataloger’s Learning Workshop

  20. Ontologies • Part of the Semantic Web suite of technologies • Ontologies are: • Published in a Namespace (like a URL) • Consist of Objects, Associations, and Instances • Completely analogous to Controlled Vocabularies • Terms, Relationships, Application of the term to some Thing Developed by the Association of Library Collections & Technical Services and Library of Congress’s Cataloger’s Learning Workshop

  21. Topic Map Model (Index) Knowledge Layer (Content) Information Layer Developed by the Association of Library Collections & Technical Services and Library of Congress’s Cataloger’s Learning Workshop

  22. Information Layer The Information Layer • The lower layer contains the content • usually digital, but need not be • can be in any format or notation • can be text, graphics, video, audio, etc. Developed by the Association of Library Collections & Technical Services and Library of Congress’s Cataloger’s Learning Workshop

  23. The Knowledge Layer • The upper layer consists of topics and associations • Topics represent the subjects that the information is about • Associations represent relationships between those subjects knowledge layer
