Controlled Vocabulary & Thesaurus Design

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!

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

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
