Relational data exchange deals with translating a relational database instance over some source schema into a relational database instance over some target schema, according to a ...
We introduce a framework for semantic interpretation in which dependency structures are mapped to conceptual representations based on a parsimonious set of interpretation schemata...
We investigate mca-programs, that is, logic programs with clauses built of monotone cardinality atoms of the form kX , where k is a non-negative integer and X is a finite set of ...
The notion of assumption-based framework generalises and re nes the use of abduction to give a formalisation of non-monotonic reasoning. In this framework, a sentence is a non-mon...
