Um modelo computacional para a construção de sistemas educacionais adaptativos e semânticos.

Abstract

This research examines the design and effective development of adaptive and semantic Web-based educational systems, integrating artificial intelligence techniques and semantic Web-based technologies. In this sense, this research presents a solution in order to ensure the effective construction of such educational systems, which means the integration of ontologias, agents and semantic Web services. As a consequence, the following goals are 1) to propose a conceptual model to build such educational environments; 2) to propose and to implement a computational model based on ontologies, agents, and semantic Web services; 3) to propose and to implement an interoperability model between edudational applications. Moreover, results obtained from three case studies (within Math and Medicine domains) are provided to evaluate the feasability of the thesis. The outcomes achieved were the conception and development of such models and the contributions are summarized as follows: i) the proposition of models to adaptive and semantic Web-based educational environments; ii) to ensure the development and maintenance of such educational sysems in an easy way; iii) to provide an structure to large-scale production of such environments and to different domains and iv) to provide the capability for universities to cooperate in the production of learning resources and access to students who needs this kind of technology as in Brazil as in abroad.
