Modeling in Qualitative Reasoning

  • Hannes Werthner


The problem of when and how to use a model (or formula) was one of the main motivations in the first works of qualitative reasoning, i.e. the program NEWTON and its application to the roller coaster problem [de Kleer 77]. Thus, this part leads back to one of the initial objectives, i.e. how to build and how to select a proper model. However, the task of modeling is not specific to qualitative reasoning, it is fundamental in every scientific work. A model of the problem has to exist before we can draw conclusions or derive consequences or answer a specific question. But qualitative reasoning offers a specific approach which has one advantage: since it takes a radical point of view, it is satisfied with very little information. Modeling — as a well-identified task distinguished from behavior generation and explanation — represents a major issue and main challenge of qualitative reasoning.
