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 The act of abstracting, separating, or withdrawing, or the state of being withdrawn; withdrawal.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. Hamilton. [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 objects. [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 WordNet (r) 2.0 :

abstraction 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. (1998-06-04)
