We introduce a general formalism of production inference relations that posses both a standard monotonic semantics and a natural nonmonotonic semantics. The resulting nonmonotonic...
Abstract. Earlier we introduced Constraint Lambda Calculi which integrate constraint solving with functional programming for the simple case where the constraint solver produces no...
The use of policy-based mechanisms significantly reduces the complexity associated with applicational development and operation. In particular, history-based policies allow the s...
Abstract. We present a theory of proof denotations in classical propologic. The abstract definition is in terms of a semiring of weights, and two concrete instances are explored. ...
Abstract. We propose a descriptive high-level language XDTrans devoted to specify transformations over XML data. The language is based on unranked tree automata approach. In contra...
