Natural Deduction style presentations of program logics are useful in view of the implementation of such logics in interactive proof development environments, based on type theory,...
The problem of answering queries using views is to find efficient methods of answering a query using a set of previously materialized views over the database, rather than accessin...
We reformulate, in the context of continuous logic, an oscillation theorem proved by G. Hjorth and give a proof of the theorem in that setting which is similar to, but simpler than...
In this paper I take a dynamic view in the spirit of the update semantics by Veltman (1996) on the first–order model construction procedure presented by Manthey and Bry (1988)....
abstraction for modeling these problems is to view the Web as a collection of (usually small and heterogeneous) databases, and to view programs that extract and process Web data au...
