Processing Deductive Databases under the Disjunctive Stable Model Semantics
نویسنده
چکیده
Cyclic covers are shown to characterise disjunctive stable models of unstratified deductive databases, and to facilitate top-down query processing, query compilation and view updating under the disjunctive stable model semantics. Such processing is shown to be more complex than comparable processing of stratified databases.

Minimal founded semantics for disjunctive logic programs and deductive databases
In this paper, we propose a variant of stable model semantics for disjunctive logic programming and deductive databases. The semantics, called minimal founded, generalizes stable model semantics for normal (i.e. non disjunctive) programs but differs from disjunctive stable model semantics (the extension of stable model semantics for disjunctive programs). Compared with disjunctive stable model ...
متن کاملPartial Evidential Stable Models for Disjunctive Deductive Databases
In this paper we consider the basic semantics of stable and partial stable models for disjunctive deductive databases (with default negation), cf. [9,16]. It is well–known that there are disjunctive deductive databases where no stable or partial stable models exist, and these databases are called inconsistent w.r.t. the basic semantics. We define a consistent variant of each class of models, wh...
متن کاملExpressive Power and Complexity of Partial Models for Disjunctive Deductive Databases 1
This paper investigates the expressive power and complexity of partial model semantics for disjunctive deductive databases. In particular, partial stable, regular model, maximal stable (M-stable), and least undeened stable (L-stable) semantics for function-free disjunctive logic programs are considered, for which the expressiveness of queries based on possibility and certainty inference is dete...
متن کاملA Characterization of the Partial Stable Models for Disjunctive Deductive Databases
We give a characterization of the partial stable models of a disjunctive deductive database P in terms of the total stable models of a suitably transformed database P tu. The transformation is based on annotating the atoms in the given database by the truth values true (\t") and undeened (\u"). Currently many fast algorithms are being developed for computing the total stable models of disjuncti...
متن کاملPossible Model Semantics for Disjunctive Databases
This paper presents a novel approach to the semantics of deductive databases. The possible model semantics is introduced as an alternative approach to the classical minimal model semantics. The possible model semantics can distinguish both inclusive and exclusive disjunctions, and provide a exible mechanism for inferring negation in disjunctive databases. The possible model semantics is charact...
