  The Aristotelian trichotomy distinguishes three aspects of argumentation:
Logos, Ethos, and Pathos. Even rich argumentation representations like the
Argument Interchange Format (AIF) are only concerned with capturing the Logos
aspect. Inference Anchoring Theory (IAT) adds the possibility to represent
ethical requirements on the illocutionary force edges linking locutions to
illocutions, thereby allowing to capture some aspects of ethos. With the recent
extensions AIF+ and Social Argument Interchange Format (S-AIF), which embed
dialogue and speakers into the AIF argumentation representation, the basis for
representing all three aspects identified by Aristotle was formed. In the
present work, we develop the Trichotomic Argument Interchange Format (T-AIF),
building on the idea from S-AIF of adding the speakers to the argumentation
graph. We capture Logos in the usual known from AIF+, Ethos in form of weighted
edges between actors representing trust, and Pathos via weighted edges from
actors to illocutions representing their level of commitment to the
propositions. This extended structured argumentation representation opens up
new possibilities of defining semantic properties on this rich graph in order
to characterize and profile the reasoning patterns of the participating actors.
