In plane elementary geometry, the concept of similar triangles not only forms an important foundation for trigonometry, but it also can be used to solve many geometric problems. T...
We study active integrity constraints and revision programming, two formalisms designed to describe integrity constraints on databases and to specify policies on preferred ways to...
This paper surveys terminological representation languages and feature-based unification grammars pointing out the similarities and differences between these two families of att...
Because botanical taxonomies are prototypical classifications it would seem that it should be easy to formalize them as concept lattices or type hierarchies. On closer inspection,...
It is widely recognized that there is a body of mathematics which is crucial to the underpinning of computer science, software engineering, and information and communications tech...
