Modeling the domain: An introduction to the expert module

Abstract

Acquiring and representing a domain knowledge model is a challenging problem that has been the subject of much research in the fields of both AI and AIED. This part of the book provides an overview of possible methods and techniques that are used for that purpose. This introductory chapter first presents and discusses the epistemological issue associated with domain knowledge engineering. Second, it briefly presents several knowledge representation languages while considering their expressivity, inferential power, cognitive plausibility and pedagogical emphasis. Lastly, the chapter ends with a presentation of the subsequent chapters in this part of the book. © 2010 Springer-Verlag Berlin Heidelberg.
