Construction of revisions by explanations
Falappa, Marcelo Alejandro - Simari, Guillermo Ricardo

Formato:	Objeto de conferencia, Objeto de conferencia
Enlaces:	Belief Revision systems are logical frameworks to modeling the dynamics of knowledge. That is, how to modify our beliefs when we recieve new information. The main problem arises when the information is inconsistent with beliefs that represents our epistemic state.…

Notions of relevance for modeling the dynamics of belief
Falappa, Marcelo Alejandro - Maguitman, Ana Gabriela

Formato:	Objeto de conferencia, Objeto de conferencia
Enlaces:	We identify different kinds of relevance relations between formulas that emerge in the process of belief revision. Informal definitions for alternative notions of relevance are suggested and a set of schemas and intuitive postulates for formalizing these notions are proposed.
