We define the semantics of logic programs with (abstract) constraint atoms in a way closely tied to default logic. Like default logic, formulas in rules are evaluated using the cl...
Discovery of suitable web services is a crucial task in Spatial Data Infrastructures (SDI). In this work, we develop a novel approach to the discovery of geoprocessing services (WP...
In this paper we reexamine the place and role of stable model semantics in logic programming and contrast it with a least Herbrand model approach to Horn programs. We demonstrate ...
In this paper we discuss the question which properties of a formally verified component are preserved when the component is changed due to an adaption to a new use. More specific...
When monitoring a system wrt. a property defined in a temporal logic such as LTL, a major concern is to settle with an adequate interpretation of observable system events; that is,...
