General description

Name: Classification
Submitted by: ValentinaPresutti
Also Known As:
Intent: To represent the relations between concepts (roles, task, parameters) and entities (person, events, values), which concepts can be assigned to. To formalize the application (e.g. tagging) of informal knowledge organization systems such as lexica, thesauri, subject directories, folksonomies, etc., where concepts are first-order elements.


Competency Questions:
  • What concept is assigned to this entity?
  • Which category does this entity belong to?
Solution description: -
Reusable OWL Building Block: (1235)
Consequences: It is possible to make assertions about e.g., categories, types, roles, which are typically considered at the meta-level of an ontology. Instances of Concept reify such elements, which are therefore put in the ordinary domain of an ontology. It is not possible to parametrize the classification over different dimensions e.g., time, space, etc.
Scenarios: Mac OSX 10.5 is classified as an operating system in the Fujitsu-Siemens product catalog.

The Classification Content OP locally defines the following ontology elements:

Class Concept (owl:Class) A concept is a Social Object. The classifies relation relates concepts to entities at some time

Concept page

Class Entity (owl:Class) Anything: real, possible, or imaginary, which some modeller wants to talk about for some purpose.

Entity page

ObjectProperty classifies (owl:ObjectProperty) A relation between a Concept and an Entity, e.g. the Role 'student' classifies a Person 'John'.

classifies page

ObjectProperty is classified by (owl:ObjectProperty) A relation between a Concept and an Entity, e.g. 'John is considered a typical rude man'; your last concert constitutes the achievement of a lifetime; '20-year-old means she's mature enough'.
