Named Concept Cluster

A Named Concept Cluster is a concept cluster that is a named cluster (whose category set members are in some semantic relationship to each other)

• AKA: Category Semantic Class Set, Type, Classification.
• Context:
  • It can (typically) have a Concept Class Identifier, such as a Category Label.
  • It can (typically) represent a Composite Concept.
  • It can (often) have a Category Definition.
  • It can range from being a Finite Category (such as a binary category) to being an Infinite Category.
  • It can be produced by a Clustering Task (to facilitate the understanding of some aspect of a Domain).
  • It can be an input to a Classification Task.
  • It can be a part of a Category Set (in some semantic relation to each other, such as in a knowledge base).
• Example(s):
  • an Entity Class, such as Mammal (which includes humans and dogs).
  • A Part-of-Speech Role, e.g. a Class Noun.
  • A Location Type.
  • an IsA Relation: be a Parent Concept(Superclass Role) or a Child Concept(Subclass Role).
  • A Tree of Life.
  • a Concept Hierarchy.
  • a Tag Set.
  • …
• Counter-Example(s):
  • a specific Physical Entity, such as some specific molecule.
  • a Concept Instance, such as the named person Gabor Melli.
  • a specific Word Mention.
  • this specific moment in time.
  • the concept of Time.
