Abstract. Formal semantics for XQuery with side-effects have been proposed in [13, 16]. We propose a different semantics which is better suited for database compilation. We substan...
We dene a preferential semantics based on stable generated models for a very general class of temporal deductive databases. We allow two kinds of temporal information to be repre...
Aspects of semantic interpretation, such as quantifier scoping and reference resolution, are often realised computationally by non-monotonic operations involving loss of informati...
The wide scale usage of OWL for the formalization of real-world ontologies is currently influenced by important limitations which concern both its expressivity and the efficiency ...
Our previous work [26] introduced Belief Logic Programming (BLP), a novel form of quantitative logic programming with correlation of evidence. Unlike other quantitative approaches ...
