Abstract

Im Rahmen dieser Arbeit wird eine Vorgehensweise entwickelt, die die Fixierung auf das Wort und die damit verbundenen Schwächen überwindet. Sie gestattet die Extraktion von Informationen anhand der repräsentierten Begriffe und bildet damit die Basis einer inhaltlichen Texterschließung. Die anschließende prototypische Realisierung dient dazu, die Konzeption zu überprüfen sowie ihre Möglichkeiten und Grenzen abzuschätzen und zu bewerten. Arbeiten zum Information Extraction widmen sich fast ausschließlich dem Englischen, wobei insbesondere im Bereich der Named Entities sehr gute Ergebnisse erzielt werden. Deutlich schlechter sehen die Resultate für weniger regelmäßige Sprachen wie beispielsweise das Deutsche aus. Aus diesem Grund sowie praktischen Erwägungen wie insbesondere der Vertrautheit des Autors damit, soll diese Sprache primär Gegenstand der Untersuchungen sein. Die Lösung von einer engen Termorientierung bei gleichzeitiger Betonung der repräsentierten Begriffe legt nahe, dass nicht nur die verwendeten Worte sekundär werden sondern auch die verwendete Sprache. Um den Rahmen dieser Arbeit nicht zu sprengen wird bei der Untersuchung dieses Punktes das Augenmerk vor allem auf die mit unterschiedlichen Sprachen verbundenen Schwierigkeiten und Besonderheiten gelegt.
