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

Abstract

Für die automatische Erschließung natürlich-sprachlicher Dokumente in einem Informationssystem wurde ein Verfahren zur automatischen thematischen hierarchischen Klassifikation der Texte entwickelt. Die dabei gewonnene Ordnungsstruktur (Begriffsnetz) wird beim Retrieval als Recherchehilfe engeboten. Die Klassifikation erfolgt in vier Stufen: Textindexierung, Prioritätsklassenbildung, Verknüpfung der begriffe und Vernetzung der Prioritätsklassen miteinander. Die so entstandenen Wichtigkeitsstufen sind die Hierarchieebenen der Klassifikation. Die während des Clusteringverfahrens erzeugten Begriffs- und Dokumenten-Gruppierungen bilden die Knoten des Klassifikationsnetzes. Die Verknüpfung zwischen den Knoten benachbarter Prioritätsklassen repräsentieren die Netzwege in diesem Netz. Die Abbildung der Suchfrage auf dieses Begriffsnetz wird zur Relevanzbeurteilung der wiedergewonnenen Texte benutzt
