The aspects in question include the argumentation interaction, which is typically a dialogue; the construction and presentation of arguments for or against a proposition; the interpretation of arguments; the knowledge representation required to build and interpret arguments; theory of rhetoric; and applications such as agent negotiation, legal argument, and decision-support systems.
argument schemas, which are such an advance and pervade the entire book, are briefly reintroduced in every chapter, instead of being presented in one authoritative chapter.
