Sneak Peek at Ontology Master

Published on

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.

Sneak Peek at Ontology Master

  1. 1. Bob Kasenchak Production Coordinator DHUG 2014
  2. 2. WHAT IS AN ONTOLOGY? Cousin of a thesaurus Represents detailed relationships between concepts More specific broader/narrower relationships More specific associative relationships Ontology Languages and Standards include: Common Logic (ISO 24707) OWL (Web Ontology Language) – Markup language Various RDF (Resource Description Framework) family of Markup languages Copyright 2014 Access Innovations, Inc.
  3. 3. ONTOLOGIES VS THESAURI Copyright 2014 Access Innovations, Inc. Thesaurus Broader Terms Narrower Terms Related Terms Ontology Is a(n) example of… Is a part of.. Has part Has member Uses… Eats… Causes… Both have synonyms (Non-Preferred Terms) Ontology
  4. 4. 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 Copyright 2014 Access Innovations, Inc.
  5. 5. 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 Copyright 2014 Access Innovations, Inc.
  6. 6. ONTOLOGY OR THESAURUS? For many cases, a thesaurus is perfect for Organizing concepts in a domain Classifying documents Auto-suggesting search terms …and most other publishing needs Copyright 2014 Access Innovations, Inc.
  7. 7. 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) Copyright 2014 Access Innovations, Inc.
  8. 8. ONTOLOGICAL EXAMPLE Copyright 2014 Access Innovations, Inc.
  9. 9. ONTOLOGIES SOUND COOL! Do I need one? Maybe! Maybe not! What’s the downside? Labor-intensive and time-consuming to build Require intensive expert review Therefore, more expensive and longer projects Copyright 2014 Access Innovations, Inc.
  10. 10. THEN WHY ARE YOU TELLING US ABOUT ONTOLOGIES IN THE FIRST PLACE? Copyright 2014 Access Innovations, Inc.
  11. 11. ONTOLOGY MASTER Access Innovations is developing an ontology construction and management application to meet demand in the marketplace: Ontology Master Sister product of Thesaurus Master Based on the same framework Same easy-to-use interface Works seamlessly with MAI Copyright 2014 Access Innovations, Inc.
