	abstract = {We show how declarative diagnosis techniques can be extended to cope with verification of operational properties, such as computed and correct answers, and of abstract properties, such as depth(k) answers and groundness dependencies. The extension is achieved by using a simple semantic framework, based on abstract interpretation. The resulting technique (abstract diagnosis) leads to elegant bottom-up and top-down verification methods, which do not require to determine the symptoms in advance, and which are effective in the case of abstract properties described by finite domains.},

	abstract = {The paper extends the Abstract Diagnosis framework to Modular Abstract Diagnosis, where we are concerned with programs composed of separate modules. Our theory of abstract diagnosis can be applied to modular diagnosis even if our concrete semantics is not OR-compositional. Abstract diagnosis is a generalization of declarative diagnosis, where we consider operational properties, i.e. observables, which are properties which can be extracted from a goal computation.},
