Abstract

In this paper we present possible roles of semi-intelligent cognitive agents (SICA) embedded in the distance learning/instruction or e-learning conceptual framework, i.e. in  learning/tutoring/instruction systems  working on the Internet or an Intranet network platform.
The problem analysis employs the TOGA (Top-down Object-based Goal-oriented Approach) methodological and ontological frameworks. The TOGA  ontology and methodology is shortly described. The specification of SICAs  starts from the definition of an e-Learning system and identification of its necessary components. E-learning system processes are seen as a cognitive  transfer of knowledge from humans and different e-documents to humans as end-users of Distance Learning Systems . Cognitive  Knowledge Transfer (CKT) is performed by Knowledge Providers, such as, professors, tutors and other specialists of a selected subject matter. It is based on the cognitive communication between them and remote students as knowledge receivers.We identify  generic scenarios of  CKT in order to distinguish such mental processes which can be allocate to SICAs. Criteria of the specification, possible roles and functional architectures of SICAs in frame of IDLS are discussed. The presented analysis is a base for the modification of the ENEA e-learning system called "Integra Module".
