Abstract

Die Ergebnisse automatischen Indexierens nach Worthäufigkeit werden in verschiedenen Varianten gezeigt. Zuerst werden die Textwörter mit einer fortlaufenden Numerierung maschinell selegiert, dann alphabetisch sortiert mit Häufigkeitsangaben. Durch die Bildung von Quasi-Stämmen läßt eine Frequenzliste dominierende Fachgebiete erkennen. Danach wird noch eine Ordnung nach Begriffen vorgeführt. Sie zeigt, wie man beim Retrieval hohe Vollständigkeits- oder hohe Genauigkeitsraten erzielen kann
