Qualitative Reasoning is characterised by making knowledge explicit in order to arrive at efficient reasoning techniques. It contrasts with often intractable quantitative models. W...
In order to support verification, validation and analysis of dynamic Operations Research (OR) models a method of testing models against data is required. In the case of the QCM qu...
We present a new algorithm for reasoning in the description logic SHIQ, which is the most prominent fragment of the Web Ontology Language OWL. The algorithm is based on ordered bi...
We present a theory of a modeler's problem decomposition skills in the context of optimal reasonzng -- the use of qualitative modeling to strategically guide numerical explor...
We present an new Prot´eg´e plugin for constructing a minimal satisfiability model of an OWL ontology and visualizing it in the original music score notation.
