 Finally, Ciardelli and Roelofsen (2015), Ciardelli (2016), and van Gessel (2016) develop a system that integrates inquisitive semantics with dynamic epistemic logic (van Ditmarsch et al. 2007), in order to formally model the information states and inquisitive states of the participants of a discourse, and how these states change when a question is asked or a statement is made. It also provides a semantics for question-embedding predicates like ‘know’ and ‘wonder’ (see also section 4).
