    Abstract
    Bewertung wissenschaftlicher Forschungsergebnisse aus einer elektronischen Datenbank heraus? Rangordnungen der wichtigsten Institutionen, Wissenschaftler, Zeitschriften und sogar Länder in Fachdisziplinen nach Einfluss? Markierung "heißer", hochaktueller Artikel? Auflisten der hochzitierten Forschungsfronten in den einzelnen Wissenschaftsdisziplinen? Und das alles auf Knopfdruck und nicht mittels umständlicher szientometrischer Verfahren? Geht so etwas überhaupt? Es geht. Mit den "Essential Science Indicators" (ESI) legt das ISl ein webbasiertes Informationssystem zur Wissenschaftsevaluation vor, das einzigartige Ergebnisse präsentiert und in der Tat ausgesprochen einfach zu bedienen ist. Aber es geht, verglichen mit ausgeklügelten Methoden der empirischen Wissenschaftsforschung, nicht alles. Wo liegen die Grenzen des Systems? Wir werden die Arbeitsweise der ESI, seine Datenbasis, die eingesetzten informetrischen Algorithmen - und deren methodischen Probleme, die Suchoberfläche sowie die Ergebnisdarstellung skizzieren. Als Beispiel dienen uns Aspekte deutscher Forschung. Etwa: In welcher Disziplin haben Deutschlands Forscher den größten internationalen Einfluss? Welches deutsche Institut der Neurowissenschaften kann aufglobaler Ebene mitmischen? Oder: Welcher in Deutschland tätige Wissenschaftler führt eine disziplinspezifische Rangordnung an?Letztlich: Wer braucht die "Essential Science Indicators"? - Wir testeten die Essential Science Indicators Mitte Februar 2002 anhand der Version vom 1. Januar 2002, die das Zehn-Jahres-Intervall 1991 bis 2000 sowie die ersten zehn Monate aus 2001 berücksichtigt.
