Structured explanations as a support to model problem-solving in a Task-Method paradigm
Francky Trichet, Pierre Tchounikine · 1997
. Task and Method notions can be used as a paradigm to help the modelling-team to structure rough expert knowledge. In such a context an important difficulty is to keep in mind a synthetic understanding of how the characteristics of all the Tasks and Methods interfere with each other. In this article, we present how the modelling team can be given a synthetic understanding of the model by the use of explanation modules that propose synthetic points of view on the model. We present how we define these explanations using three levels: what is related to the paradigm, what is related to the general characteristics of the model one considers and what is related to the particular model one considers. We also highlight what differentiates explanations and solving traces, present the putting into practice of our approach and compare it with some knowledge acquisition tools. 1 Introduction When constructing a knowledge based system (KBS) the first step is the elaboration of an ab...
