The Structure of a Semantic Theory
Language, 1963This paper does not attempt to present a semantic theory of a natural language, but rather to characterize the form of such a theory. A semantic theory of a natural language is part of a linguistic description of that language. Our problem, on the other hand, is part of the general theory of language, fully on a par with the problem of characterizing ...

Structuring theories on consequence
1988Building on the work of Goguen and Burstall on institutions and on Tarski's notion of deductive system, a categorial framework for manipulating theories in an arbitrary logic is presented. Its main contribution is the formalisation of the semantics of theory-building operations on top of a consequence relation.

Physical Review, 1955
Die relativistischen Korrekturen für die in die HFS eingehenden Ein-Elektronen-Integrale werden normalerweise mit dem reinen Coulomb-Feld des Kerns berechnet. Abweichend wird in der vorliegenden Arbeit die Abschirmung des Leuchtelektrons durch die inneren Elektronen mittels eines ortsabhängigen Korrekturfaktors im Coulomb-Potential berücksichtigt.

Knowledgebases as structured theories
1988According to the structural paradigm of knowledge representation, knowledgebases are built by organizing facts along the semantic primitives of a conceptual modelling approach. Previous work of the authors has shown how these organizational principles can be brought into the logical view of knowledge representation by defining mechanisms for developing
