    Abstract
    Die Ermittlung von Kerninformationen mittels informetrischer Methoden erfordert die Nutzung formaler Bewertungskriterien wie Publikationshäufigkeit, Zitierhäufigkeit und Patentfamiliengröße. Es werden die Zeitabhängigkeit, die Austauschbarkeit und die Voraussetzungen für die Anwendung der formalen Bewertungskriterien erläutert.
