The classification content ontology design pattern. This CP represents the realtions between concepts e.g., roles, task, and entities to which concepts are assigned to e.g., person, activities. The CP is extracted form DOLCE Ultra Lite ontology.
covers requirements
What concept is assigned to this entity? Which category does this entity belong to?
It is possible to make asser tions 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.
has 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.
related cps
Typically combined with descriptionandsituation. It is specialized by cat:objectrole. The n-ary classification CP provides an alternative to this if classification has to be qualified over different dimensions.
scenarios
Mac OSX 10.5 is classified as an an operating system in the Fujitsu-Siemens product catalog.
A concept is a Social Object.
The classifies relation relates concepts to entities at some time, but time can only be expressed in the alternative pattern: timeindexedclassification.
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'.
