Dung's Argumentation Framework is a formal model used to represent and evaluate arguments and their interactions. It provides a structured way to analyze how arguments can support or attack one another, helping to determine which arguments are acceptable in a given context. The framework consists of a set of arguments, a relation of attack between them, and a notion of acceptability. By defining these components, Dung's framework allows for the exploration of various argumentation scenarios, facilitating clearer reasoning and decision-making in fields like artificial intelligence and law.
