Abstract
A variant of Reiter's default logic is proposed as a logic for reasoning with
(defeasible) observations. Traditionally, default rules are assumed to
represent generic information and the facts are assumed to represent specific
information about the situation, but in this paper, the specific information
derives from defeasible observations represented by (normal free) default
rules, and the facts represent (hard) background knowledge. Whenever the
evidence underlying some observation is more refined than the evidence
underlying another observation, this is modelled by means of a priority
between the default rules representing the observations. We thus arrive at an
interpretation of prioritized normal free default logic as an observation
logic, and we propose a semantics for this observation logic. Finally, we
discuss how the proposed observation logic relates to the multiple extension
problem and the problem of sensor fusion.
