A Reasoning System for a First-Order Logic of Limited Belief
  Logics of limited belief aim at enabling computationally feasible reasoning
in highly expressive representation languages. These languages are often
dialects of first-order logic with a weaker form of logical entailment that
keeps reasoning decidable or even tractable. While a number of such logics have
been proposed in the past, they tend to remain for theoretical analysis only
and their practical relevance is very limited. In this paper, we aim to go
beyond the theory. Building on earlier work by Liu, Lakemeyer, and Levesque, we
develop a logic of limited belief that is highly expressive while remaining
decidable in the first-order and tractable in the propositional case and
exhibits some characteristics that make it attractive for an implementation. We
introduce a reasoning system that employs this logic as representation language
and present experimental results that showcase the benefit of limited belief.
