- Abstract
- Semantische Repräsentationssprachen (SRL) dienen der strukturierten Darstellung und Handhabung von Wissen. Dieses Wissen, das durch die menschliche Sprache vermittelt und in Informationssystemen bereitgestellt werden soll, muß benutzergerecht strukturiert werden, um ein Wiederauffinden effektiv und effizient zu gewährleisten. Um diesen Zusammenhang zwischen dem syntaktischen Aufbau einer SRL und der Systemleistung fundiert untersuchen zu können, sind Beschreibungskonzepte erforderlich, mit denen sich die relevanten Aspekte von SRL und deren Einfluß auf eine Retrievalumgebung hinreichend exakt darstellen lassen. Im vorliegenden Beitrag wird ein solches Beschreibungsmodell vorgestellt

- Abstract
- Untersuchung, inwieweit tiefergehende semantische Verfahren, wie sie z.T. in der Artificial Intelligence entwickelt wurden, sinnvoll im Information Retrieval eingesetzt werden können. Dazu werden in einem implementierten System, ausgehend von einer 'mächtigen' Repräsentationssprache (prädikatenlogische Sprache mit typisierten Variablen), durch sukzessives Reduzieren der syntaktischen Mittel 'weniger mächtige' Repräsentationssprachen erzeugt und jeweils Retrievaltests durchgeführt. Insgesamt werden 8 verschiedene Sprachen miteinander verglichen
