How to extract negative information from programs is an important issue in logic programming. Here we address the problem for functional logic programs, from a proof-theoretic pers...
This paper explores the applicability of the new paradigm of Multi-dimensional Dynamic Logic Programming to represent an agent’s view of the combination of societal knowledge dyn...
We propose a general scheme for the cooperation of different constraint solvers. A uniform interface for constraint solvers allows to formally specify information exchange between...
We describe a system for the synthesis of logic programs from specifications based on higher-order logical descriptions of appropriate refinement operations. The system has been ...
Logic programming rules are provided to capture the rules governing formal poetry in Spanish. The resulting logic program scans verses in Spanish to provide their metric analysis. ...
Abstract. In this paper a semantic approach for the specification and the management of databases with evolving schemata is introduced. It is shown how a general object-oriented m...
Generalized databases will be examined, in which attributes can be sets of attributes, or sets of sets of attributes, and other higher type constructs. A precise semantics will be ...
Abstract. Dominance constraints are widely used in computational linguistics as a language for talking and reasoning about trees. In this paper, we extend dominance constraints by ...
