    Abstract
    Die empirische Wissenschaftsforschung arbeitet bei den Indikatoren wissenschaftlicher Leistung und wissenschaftlicher Wirkung mit Publikations- und Zitationsraten. Die vorliegende Arbeit befaßt sich mit dabei auftretenden methodischen Problemen. Was ist überhaupt eine Publikation? Was heißt Zitation? Zentral ist auch die Zählbasis, d.h. die Einheitenbildung: Was ist 1 Publikation? und: Was ist 1 Zitation? Bei Printpublikationen gibt es eine Reihe von beachtenswerten Faktoren (u.a. Mehrautorenwerke, Gewichtungsfaktoren wie den Impact Factor, Dokumenttypen). Bei elektronischen Publikationen im Internet mit ihrem dynamischen Charakter ist die Einheitenbildung noch weitaus problematischer. Zitationen, verstanden als zitierte Publikationen, werfen alle methodischen Probleme der Publikationseinheiten auf, hinzu kommen weitere, spezifische Probleme. Lösungsmöglichkeiten im syntaktischen Bereich (Relativierung auf Textseiten oder Zeichen) ändern am grundlegenden Problem nur wenig, Lösungsversuche im semantischen Bereich (etwa im Rahmen der semantischen Informationstheorie) sind im Rahmen der Publikations- und Zitationsanalysen nicht durchführbar und verweisen sowohl auf themenanalytische Methoden als auch auf die Wissenschaftstheorie. Mit diesem Working Paper wollen wir vor allem auf offene Probleme hinweisen; "endgültige" Lösungen wird der Leser nicht finden, wohl aber Lösungsvorschläge, die meist durchaus noch diskussionswürdig sind. In der Informationswissenschaft wie in der Wissenschaftsforschung sind wir bisher viel zu sicher davon ausgegangen, daß wir wissen, was Publikationen und Zitationen sind
