Dialogue semantics: From cognitive structures to positive and negative learning

Part of language processing and understanding is building semantic structures, or situation models. In this paper it is argued on the basis of previous works how dialogue semantics provides representations for formations of such cognitive structures. This cognitive twist is extended to a brief dialogical model of learning which embraces a fourfold partition into learning from the positive, learning from the negative, positive learning and negative learning, the latter being two prime areas of interest of PLATO. Thus, this chapter contributes to a semantic derivation and clarification of different forms of learning on a propositional level.
