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!

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

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

Taxonomies are Everywhere

Especially in product websites Examples include

Yahoo!, Amazon, HomeDepot, etc.

To see them you need to just look around

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
