Documentary abstracting: Toward a methodological model

In the general abstracting process (GAP), there are two types of data: textual, within a particularly framed trilogy (surface, deep, and rhetoric); and documentary (abstractor, means of production, and user demands). For its development, the use of the following disciplines, among others, is proposed: linguistics (structural, transformational, and textual), logic (formal and fuzzy), and psychology (cognitive). The model for that textual transformation is based on a system of combined strategies with four key stages: reading-understanding, selection, interpretation, and synthesis.
