18.5 A larger ontology: Question

Exercise: A larger ontology

This exercise may not have only one answer -- there might be several good answers.

Draw a lattice that has at least the following categories:

  • Entity
  • Absurdity
  • Man
  • Boy
  • Woman
  • Girl
  • Red
  • Green
  • Blue
  • Dog
  • Cat
  • Mouse
  • Bee
  • TV
  • Book
  • Hedge
  • Tree
  • Flower
  • Sadness
  • Joy
  • Anger
  • Being-in-love

You are encouraged not to let everything be an immediate subtype of Entity, but to invent categories which gather some of these categories into supertypes. You may even wish to have more than one supertype in between these categories and Entity, thereby making the depth of the lattice greater.
