Heather Hedden, Taxonomy Consultant at Hedden Information Management, began her afternoon workshop explaining why taxonomies are important. Explaining that a taxonomy is a controlled vocabulary organized into a hierarchical structure, she added that taxonomies help control and organize content.
The catchphrase is "things, not strings." An example of this is results of a search can be extracted from concepts, not just the words.
Taxonomies provide consistent concepts for tagging and retrieval. They bring together synonyms for the same content. They organize concepts into hierarchies, which guide users to specific topics, and into facets for filtering and refining searches.
An ontology is a model of a knowledge domain. it includes relationships, they are customized semantic relationships.
Knowledge organization systems: term list, name authority, taxonomy, thesaurus, ontology, from simplest to most complex and expressive. Ontology is the semantic model, can connect to taxonomies, term lists, etc.
