 Excitingly, there has been a recent surge in the recent development of information logics that combine the flexibility of categorial information theory with the subject matter of dynamic epistemic logics in order to design  substructural epistemic logics. Sedlar (2015) combines the modal epistemic logics of implicit knowledge and belief with substructural logics in order to capture the availability of evidence for the agent. Aucher (2015, 2014) redefines dynamic epistemic logic as a substructural logic corresponding to the Lambek Calculi of categorial information theory. Aucher shows also that the semantics for DEL can be understood as providing a conceptual foundation for the semantics of substructural logics in general. See Hjortland and Roy (2016) for an extension of Aucher’s approach to soft information
