    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

    Abstract
    Eine fundierte Untersuchung der Anforderungen an Experimente im Information Retrieval bedarf einer geeigneten Sprache, die es erlaubt, alle relevanten Aspekte adäquat zu beschreiben. Der Beitrag versucht, ein solches Begriffsgerüst zu entwickeln. Als grundlegende Begriffe dienen die 4 Kategorien: experimentelle Faktoren, situative Faktoren; Experimentalobjekte und Beobachtungsvariablen. Das Begriffsgerüst wird anhand praktischer Beispiele illustriert
