- belief revision — (artificial intelligence) The area of theory change in which preservation of the information in the theory to be changed plays a key role.

Usually, an ordering on the sentences of the theory is used to determine priorities among sentences, so that those with lower priority can be retracted. This ordering can be difficult to generate and maintain. The postulates of the AGM Theory for Belief Revision describe minimal properties a revision process should have.
