Fig. 4.16An agenda that realises a user turn

Analogously, Fig. 4.17 depicts an exchange, which is formed by an agenda that provides both moves containing grammars and utterances. In practice, the utterances relate to questions and the grammars relate to possible answers to these questions. Depending on the user’s answer one of the answer moves is processed by the ASDM. For generating a new belief, the specific move provides a semantic individual similarly to user and system turns. The question_Agenda points at two subsequent agendas: one that may be processed if the user replies positively and another one if he does not wish to start cooking now. In case of such a negative reply, an agenda that provides a user turn could be activated. The system would listen until the user, for example, utters: “I want to start cooking now!”. The two relations requires and mustNot point at semantics. However, the requires relation can only be evaluated as valid if the related semantic individual is referenced by a belief individual, i.e. the meaning of the semantic is shared between user and system.
