Uma linha de produto de software baseada na web semântica para sistemas tutores inteligentes.

Abstract

This research is related to design and building effective and large scale Intelligent Tutoring Systems under the Semantic Web perspective. It deals with clearly an interdisciplinary theme which surrounds a conjunction of aspects related to Artificial Intelligence, Semantic Web and Software Engineering, applied to those kind of educational environments. Thus, this work, proposes a study about the development of Intelligent Tutoring Systems as part of Virtual Learning Environments for presence or distance education, taking to account characteristics of such as reuse and large scale development. In this sense, an assessment of the current ITS construction approaches adequacy, along with the definition of an architecture containing the Intelligent Tutoring Systems essential components. The proposed architecture was used to specify a product line that took into account (i) the different user profiles, (ii) the non-possession of advanced computing knowledge by the users (iii) the heterogeneity of knowledge domains this kind of systems will handle and (v) the constant change and evolution of the knowledge manipulated of this kind of systems. This way, satisfying the four mentioned considerations, a software product line based on the SemanticWeb was developed and tested. The experiments carried out to evaluate the proposed approach, in two different domains (Programming and Physics), demonstrate that it is effective in aspects such as large scale, adaptivity and evolution.
