Existenzielle Regeln
Aus International Center for Computational Logic
Existenzielle Regeln
Existenzielle Regeln sind ein Formalismus zur Wissensrepräsentation mit Anwendungen in der künstlichen Intelligenz und Datenbanken. Ihre syntaktische Allgemeinheit erlauben eine Integration von Formalismen aus der Wissensrepräsentation und aus dem Datenbankbereich. Syntaktisch sind existenzielle Regeln verwandt mit Datalog; ihre wesentliche zusätzliche Ausdrucksstärke besteht in der Möglichkeit, die Existenz von Domänenelementen zu beschreiben, die nicht von vornherein namentlich bekannt sind.
Existenzielle Regeln, sind seit längerem unter verschiedenen Bezeichnungen bekannt und die Beantwortung von Anfragen an Daten unter Einbeziehung von existenziellen Regeln ist zur Zeit Gegenstand intensiver Forschung. Typische Fragestellungen hierbei sind beispielsweise: Welche Fragmente existenzieller Regeln verbinden hohe Ausdrucksstärke mit geringer Berechnungsaufwand? Welche allgemeinen Prinzipien garantieren die Entscheidbarkeit der Anfragebeantwortung? Was sind die spezifischen Komplexitäten konkreter Fragmente? Wie entwickelt man effiziente Softwaretools für diese Aufgaben?
