<p>Disertacija se bavi problematikom adaptivnih web-baziranih sistema u oblasti e-učenja. Definisan je model sistema čije su osnovne komponente: učenik, učitelj i obučavajući materijali. Model je proširiv i domenski nezavistan. Istražena je interakcija između komponenti modela, pre svega između učenika i obučavajućih materijala. Razvijen je modul za procenu usaglašenosti potreba učenika sa jedne strane i sadržaja obučavajućih materijala sa druge strane. Korišćene su mere udaljenosti odnosno sličnosti, na taj način postignuta je delimična adaptibilnost modela. Adaptibilnost modela proširena je modulom koji koristi Ako Onda pravila generisana od strane sistema baziranog na Teoriji grubih skupova. Pravila u Ako Onda formi procenjuju uticaj obučavajućih materijala na učenika i shodno proceni vrše adaptaciju. Model je implementiran, testiran i korišćen za vršenje eksperimenata na test skupu obučavajućih materijala i učenika. Pokazano je na koji način se vrši adaptacija u okviru korišćenog sistema.</p> / <p>The dissertation deals with the problem of adaptive Web-based systems in the field of e-learning. The model whose basic components are: the student, the teacher and the learning materials is defined. The model is extensible and domain independent. The interaction between the components of the model is examined, especially among students and learning materials. Module for the conformity assessment between needs of students and the content of the learning materials is developed. The distance measures or similarity measures are used, thus is achieved a partial adaptability of the model. Adaptability of the model was extended by module that uses If Then rules generated by the system based on the Rough sets theory. If Then rules are used to estimate the impact of learning materials to students and after that, is performed the adaptation. The model was implemented, tested and used to carry out experiments on the test set of learning materials and students. It is shown how the adjustments are done.</p>
