โœฆ Synopsis


Representing and reasoning with priorities are important in commonsense reasoning. This paper introduces a framework of prioritized logic programming (PLP), which has a mechanism of explicit representation of priority information in a program. When a program contains incomplete or indefinite information, PLP is useful for specifying preference to reduce non-determinism in logic programming. Moreover, PLP can realize various forms of commonsense reasoning in AI such as abduction, default reasoning, circumscription, and their prioritized variants. The proposed framework increases the expressive power of logic programming and exploits new applications in knowledge representation.

In this paper, we investigate the decidability problem of logic program semantics and observables, focusing in particular on the least Herbrand model (or M-semantics), the C-semantics, and the S-semantics. We introduce bounded logic programs, and show that they coincide with programs such that every

Recently, Brass and Dix showed (J. Automat. Reason. 20(1) (1998) 143-165) that the well founded semantics WFS can be deรฟned as a con uent calculus of transformation rules. This led not only to a simple extension to disjunctive programs (J. Logic Programming 38(3) (1999) 167-213), but also to a new c

Program specialization optimizes programs for known values of the input. It is often the case that the set of possible input values is unknown, or this set is inยฎnite. However, a form of specialization can still be performed in such cases by means of abstract interpretation, specialization then bein
