  An approach for encoding abstract dialectical frameworks and their semantics
into classical higher-order logic is presented. Important properties and
semantic relationships are formally encoded and proven using the proof
assistant Isabelle/HOL. This approach allows for the computer-assisted analysis
of abstract dialectical frameworks using automated and interactive reasoning
tools within a uniform logic environment. Exemplary applications include the
formal analysis and verification of meta-theoretical properties, and the
generation of interpretations and extensions under specific semantic
constraints.
