Theory, algorithms, techniques and tools for producing a generalisation of a map have long been available. In this paper we study the inverse problem, namely, given two maps L and...
Spatial data mining, i.e., discovery of interesting characteristics and patterns that may implicitly exist in spatial databases, is a challenging task due to the huge amounts of s...
We establish a nonlinear lower bound for halfplane range searching over a group. Specifically, we show that summing up the weights of n (weighted) points within n halfplanes requir...
We investigate the semantics for Knowledge Query Manipulation Language KQML and we propose a semantic framework for the language. KQML is a language and a protocol to support comm...
The Wizard of Oz (WOz) technique is an experimental evaluation mechanism. It allows the observation of a user operating an apparently fully functioning system whose missing service...
