What is Ontology?

By   /  October 15, 2017  /  No Comments

ontologyOntology is a subset of Taxonomy, an Ontology: Is a Domain; contains more information about the behavior of entities and the relationships between them; includes formal names, definitions and attributes of entities; and, may be constructed using OWL, the Ontology Web Language from the W3C.

Other definitions of Ontology include:

 

  • “A data model that represents a set of concepts within a domain and the relationships among those concepts.” (Microsoft)
  • “More complex and quite formal collection of terms.” (W3C)
  • “A way to represent our knowledge on a specific topic that also allows us to share information using a common language.” (NIH)
  • “Describe and classify the entities of interest in a scientific domain in a computationally accessible fashion such that algorithms and tools can be developed around them.” (PubMed)

Businesses apply Ontologies to:

  • Harmonize data across repositories in a common language for an industry. (e.g. FIBO)
  • To share a common understanding of the structure of information among people or software agents.
  • To enable reuse of domain.
  • Understand the how the usage of a term has changed over time and thus placing a term in context.
  • To allow machines to apply more efficient Deep Learning techniques and learn better independently.

Ontologies factor the thinking about how a domain influences: choices of maps and models, rules and representations, and required operations. Using taxonomies, alone, just does not model this type of thinking well.
