- Abstract
- Nach einer kurzen Einführung in die Darmstädter Projekte WAI und AIR werden die folgenden Themen behandelt: Ein Ansatz zur automatischen Klassifikation. Statistische Relationen für die Klassifikation. Indexieren von Dokumenten als Spezialfall der automatischen Klassifikation. Klassifikation von Elementen der Relevanzbeschreibung. Klassifikation zur Verbesserung der Relevanzbeschreibungen. Automatische Dokumentklassifikation und Automatische Indexierung klassifizierter Dokumente. Das Projekt AIR wird in Zusammenarbeit mit der Datenbasis INKA-PHYS des Fachinformationszentrums Energie, Physik, Mathematik in Karlsruhe durchgeführt
