We investigate the question of whether a query can be answered using a set V of views. We first define the problem in information-theoretic terms: we say that V determines if V pr...
We present practical algorithms for accelerating geometric queries on models made of NURBS surfaces using programmable Graphics Processing Units (GPUs). We provide a generalized f...
As XQuery nears standardization, more sophisticated XQuery applications are emerging, which often exploit the entire language and are applied to non-trivial XML sources. We propos...
Service discovery is important in mobile and pervasive computing environments, where the set of resources available to an entity changes dynamically over time. This paper describe...
Spatial relations are the basis for many selections users perform when they query geographic information systems (GISs). Although such query languages use natural-language-like te...
