conceptualisation
     
         The collection of objects, concepts
        and other entities that are assumed to exist in some area of
        interest and the relationships that hold among them.  A
        conceptualisation is an {abstract}, simplified view of the
        world that we wish to represent.  For example, we may
        conceptualise a family as the set of names, sexes and the
        relationships of the family members.  Choosing a
        conceptualisation is the first stage of {knowledge
        representation}.
     
        Every {knowledge base}, {knowledge-based system}, or
        {knowledge-level agent} is committed to some
        conceptualisation, explicitly or implicitly.
