Abstract

This dissertation aims at representing concepts of medical subjects as well as statements on medical subjects independent of medical terminology, in order to overcome the problems of interpretation and further elaboration of entries in an ordering system such as SNOMED, MeSH-Thesaurus or ICD Classification. The approach of a compositional, semantic language analysis developed here implies specific demands from a conceptual modelling and utilizes the following methods: (1) a characteristics-based grammar formalism for represenatation of terminological structures, to be analyzed, (2) a terminological representation formalism for a conceptual-intensionally-oriented representation of a concept system, and (3) a modified chart-parser for grammatical derivation

Abstract

Dazu sind folgende Teile eines IR-Systems notwendig: * Informationserschließung Eine Komponente zur Erschließung und Darstellung der gespeicherten Informationen. Dieser Teil dient dazu, den Inhalt der Dokumente zu beschreiben und so darzustellen, daß aufgrund dieser Merkmale ein Dokument gefunden werden kann. Eine Möglichkeit dazu besteht darin, den Dokumenten inhaltsbeschreibende Deskriptoren zuzuordnen. Durch den Prozeß der Indexierung werden die Dokumente in eine Indexierungssprache übersetzt. * Query-Language (Abfragesprache) Eine Komponente zur Formulierung der Suchanfragen des Benutzers. Dieser Teil dient dazu, die Suchanfrage des Benutzers so zu verarbeiten, daß mit der aus der Frage gewonnenen Information über die Bedürfnisse des Benutzers die passenden Dokumente gefunden werden können. * Informationsausgabe - Informationsaufbereitung Eine Komponente zur Ausgabe der auf Grund der Suchanfrage gefundenen Informationen. Dieser Teil stellt das Ergebnis der Suchanfrage dem Benutzer zur Verfügung.
