DESCRIPTION
An ontology is a "cousin" of a thesaurus: a controlled vocabulary, enriched with a rich network of terms and relationships. Like a thesaurus, ontologies are useful for such implementations as document classification and data indexing. Marjorie M.K. Hlava, President and founder of Access Innovations, Inc. with Bob Kasenchak, a project manager of this company, outline a new feature of Data Harmony in development: Ontology Master, a module designed specifically to build and manage ontological networks.

SAMPLE RELATIONSHIPS
Cancer [IS A class of] Disease(BT)
Cancer [has subclass] Skin Cancer(NT)
Skin Cancer [IS A Subclass of] Cancer(BT)
Skin Cancer [IS CAUSED BY] UV Rays(RT)
UV Rays [CAUSES] Skin Cancer(RT)
Chemotherapy [TREATS] Skin Cancer(RT)
All of these relationships are customized and defined
for each ontology according to a simple framework
All relationships are reciprocal

HOW ONTOLOGIES ARE USED
Much in the same way as thesauri, Ontologies are powerful tools for semantic enrichment, document classification, search/retrieval enhancement, etc.
The basic process of indexing is the same; it’s the relationships between the concepts (terms) that are different

ONTOLOGY OR THESAURUS?
For many cases, a thesaurus is perfect forOrganizing concepts in a domainClassifying documentsAuto-suggesting search terms…and most other publishing needs

ONTOLOGY OR THESAURUS?
Ontologies are useful for classifying and relating domains in which defining more specific relationships are useful to the end user, for example:Biology (diseases, disease vectors, organisms)Manufacturing (suppliers, parts, products)Materials science (materials, techniques, tests)

ONTOLOGIES SOUND COOL!
Do I need one?Maybe!Maybe not!
What’s the downside?Labor-intensive and time-consuming to build
Require intensive expert reviewTherefore, more expensive and longer projects

FIRST PLACE?
