Abstrakte Argumentation
Aus International Center for Computational Logic
Abstrakte Argumentation
Argumentation ist ein wichtiges Forschungsfeld der Künstlichen Intelligenz und des nichtmonotonen Schließens, welches Anwendungen in Bereichen wie z.B. Legal Reasoning, soziale Netzwerke, E-Government, Multi-Agenten-Systeme und Decision Support findet.
Dabei hat sich das Konzept der abstrakten Argumentation Frameworks (AFs) zu einem der beliebtesten Ansätze entwickelt. Dieses relativ einfache aber sehr ausdrucksstarke Modell wurde im Jahre 1995 von Phan Minh Dung eingeführt und besteht, kurz gesagt, aus einer Menge von Argumenten und einer binären Attackrelation zwischen den Argumenten, durch die Konflikte ausgedrückt werden. Dabei ist mit "abstrakt" gemeint, dass man nicht die interne Struktur der Argumente betrachtet, sondern nur die Beziehung der Argumente zueinander, die durch die Attacken gegeben ist.
Zur Lösung der Konflikte werden unterschiedliche Semantiken herangezogen, die zulässige Mengen von Argumenten auswählen. Abhängig von der jeweiligen Anwendung genügen diese Semantiken unterschiedlichen Anforderungen.Professoren und Gruppenleiter
