Approaches to qualitative reasoning

摘要

The main approaches to qualitative reasoning are surveyed, compared and contrasted. These are the constrain based, component centred and processed based approaches. Later sections consider the efficiency of the reasoning techniques and possible applications (for instance in diagnosis and measurement interpretation). The paper concludes with a number of sections which consider representation of space and time, order ofmagnitude reasoning, hierarchical and multiple models and the method by which qualitative models might be generated.
