Conceptual Modelling and Ontology: Possibilities and Pitfalls

Modelling Decision Problems Via Birkhoff Polyhedra

A compact formulation of the set of tours neither in a graph nor its complement is presented and illustrates a general methodology proposed for constructing polyhedral models of decision problems based upon permutations, projection and lifting techniques. Directed Hamilton tours on n vertex graphs are interpreted as (n-1)- permutations. Sets of extrema of Birkhoff polyhedra are mapped to tours ...

Problems and Pitfalls in Evaluating Adaptive Systems1

Empirical studies with adaptive systems offer many advantages and opportunities. Nevertheless, there is still a lack of evaluation studies. This paper lists several problems and pitfalls that arise when evaluating an adaptive system and provides guidelines and recommendations for workarounds or even avoidance of these problems. Among other things the following issues are covered: relating evalu...
