Implementations of Allen's interval-based temporal logic and a recently developed simulation system for reasoning about space and time, both require the use of transitivity tables. Although strategies exist to construct such tables, the proofs which underly the entries in the table are both tedious to do and in some cases difficult to secure. Often a difficult proof is only obtained via lemmas; moreover,...
In this paper, we present a spatial logic which can be used to reason about topological and spatial relationships among objects in spatial databases. The main advantages of such a formalism are its rigorousness, clear semantics and sound inference mechanism. We also show how the formalism can be extended to include orientation and metrical information. Comparisons with other formalisms are discussed.
RaPiD is a knowledge-based assistant for designing removable partial dentures. It employs techniques from logic data bases, declarative graphics, and critiquing, along with expert design knowledge, to provide a CAD-style graphical interface for both instructional and professional use, the latter offering some design automation. RaPiD is being evaluated in terms of usability, clinical correctness,...
