On Thursday March 8, 2011, at 3 p.m., Ben Rodenhäuser (ILLC) will give a talk at the LIRa seminar on Doxastic Attitudes as Belief Revision Policies (joint work with Alexandru Baltag and Sonja Smets).
The talk will take place in Science Park 904, Room D1.113.
We argue for the importance of dynamic doxastic attitudes as factors determining how agents deal with information provided by various sources. Dynamic attitudes are formalized as policies (or strategies) for belief revision that are applied once informational inputs are received. We introduce various natural types of attitudes, and operations on them; we investigate the relationship between dynamic attitudes (towards sources of information) and propositional attitudes (towards pieces of information), like knowledge and belief; we study the relative strength of dynamic attitudes; and we use the approach to model Gricean implicatures.
