  Abstraction \Ab*strac"tion\, n. [Cf. F. abstraction. See
     Abstract, a.]
     1. The act of abstracting, separating, or withdrawing, or the
        state of being withdrawn; withdrawal.
        [1913 Webster]
              A wrongful abstraction of wealth from certain
              members of the community.             --J. S. Mill.
        [1913 Webster]
     2. (Metaph.) The act process of leaving out of consideration
        one or more properties of a complex object so as to attend
        to others; analysis. Thus, when the mind considers the
        form of a tree by itself, or the color of the leaves as
        separate from their size or figure, the act is called
        abstraction. So, also, when it considers whiteness,
        softness, virtue, existence, as separate from any
        particular objects.
        [1913 Webster]
     Note: Abstraction is necessary to classification, by which
           things are arranged in genera and species. We separate
           in idea the qualities of certain objects, which are of
           the same kind, from others which are different, in
           each, and arrange the objects having the same
           properties in a class, or collected body.
           [1913 Webster]
                 Abstraction is no positive act: it is simply the
                 negative of attention.             --Sir W.
           [1913 Webster]
     3. An idea or notion of an abstract, or theoretical nature;
        as, to fight for mere abstractions.
        [1913 Webster]
     4. A separation from worldly objects; a recluse life; as, a
        hermit's abstraction.
        [1913 Webster]
     5. Absence or absorption of mind; inattention to present
        [1913 Webster]
     6. The taking surreptitiously for one's own use part of the
        property of another; purloining. [Modern]
        [1913 Webster]
     7. (Chem.) A separation of volatile parts by the act of
        distillation. --Nicholson.
        [1913 Webster]

Din dicționarul The Free On-line Dictionary of Computing (27 SEP 03) :

          1. Generalisation; ignoring or hiding details to capture some
          kind of commonality between different instances.  Examples are
          abstract data types (the representation details are hidden),
          abstract syntax (the details of the concrete syntax are
          ignored), abstract interpretation (details are ignored to
          analyse specific properties).
          2.  Parameterisation, making something a function
          of something else.  Examples are lambda abstractions (making
          a term into a function of some variable), higher-order
          functions (parameters are functions), bracket abstraction
          (making a term into a function of a variable).
          Opposite of concretisation.
