Abstract

Abstracts (hier als Sammelbegriff für jegliche Form meist schriftlicher Zusammenfassungen verstanden) beruhen auf der inhaltlichen Informationsverdichtung (Kondensierung) von längeren Quelltexten (etwa Zeitungs- oder Zeitschriftenartikel). Geht man von der Menge aller Aussagen eines Originaldokumentes (auch als Volltext bezeichnet) aus, soll ein Abstract - abhängig vom gewünschten Verdichtungsgrad - nur die wichtigsten Aussagen des Volltextes oder Generalisierungen davon in redundanzfreier, grammatikalisch korrekter, textuell kohärenter und gut lesbarer Form enthalten. Durch die Verdichtung - so die zentrale informationswissenschaftliche Annahme - gewinnt der Nutzer Übersicht über die in einem (oder mehreren) Dokument(en) behandelten Themen mit wesentlich geringerem (Zeit-)Aufwand als durch die Lektüre des Originaltextes. Es ist dabei unstrittig, dass jede Form der Kondensierung zu Informationsverlusten führt. Folglich gilt es, ein Optimum an Zeitgewinn und Informationsverlust anzustreben. Abstracting, der Prozess der Erstellung von Abstracts, selbst kann als Spezialisierung der allgemeineren Textzusammenfassung (TZF) aufgefasst werden, fokussiert jedoch primär auf Fach- und Sachtexte.
