Extended Well-Founded Semantics for Paraconsistent Logic Programs
Proceedings of the International Conference on Fifth
Generation Computer Systems (FGCS'92), pp. 592-599, Ohmsha, 1992.
This paper presents a declarative semantics of logic programs which possibly
contain inconsistent information. We introduce a multi-valued
interpretation of logic programs and present the extended well-founded
semantics for paraconsistent logic programs. In this setting, a meaningful
information is still available in the presence of an inconsistent
information in a program and any fact which is affected by an inconsistent
information is distinguished from the others. The well-founded semantics is
also extended to disjunctive paraconsistent logic programs.
