We study the complexity of satisfiability for the expressive extension ICPDL of PDL (Propositional Dynamic Logic), which admits intersection and converse as program operations. Ou...
We describe BE, an implemented system for solving belief change problems in the presence of actions. We illustrate how we can use BE to compute the result of belief progression, be...
Modern semantic technology is one of the necessary supports for the infrastructure of next generation information systems. In particular, large international organizations, which u...
