Mazurets O. Information Technology for Automated Structuring of Educational Materials and Creation of Tests for Adaptive Control of the Level of Knowledge

The dissertation is devoted to the development of information technology for the automated structuring of educational materials and the creation of tests for adaptive control of the knowledge level. Information technology allows to automatically receive sets of test tasks based on input data in the form of educational materials of course. The analysis of existing methods for searching key terms in digital texts and methods of automated creation of test tasks for educational materials is implemented. The information model of the semantic structure of the educational course has been improved, which, unlike the known ones, provides a formal presentation of the semantic structure of the educational course. The semantic structure of the educational course is informative enough to automate the creation of test tasks, which are distributed by the structure of the educational materials. The method of forming the structure of educational materials and searching for key terms in them has been improved. This method, unlike the known ones, allows accounting the possibility of mutual absorption of terms and identifying as terms not only words but also phrases. New method for the automated creation of test tasks for educational materials has been developed, which uses a production model to represent the rules for the creation of test tasks. The method allows receiving test tasks sets without further formalization of educational materials. New information technology for automated creation of test tasks for educational materials has been developed, which allows receiving automatically sets of test tasks according to the input data in the form of educational materials. The resulting sets of test tasks are suitable for adaptive testing. According to the results of experimental testing of information technology of automated creation of test tasks for educational materials, it was determined that full coverage of the educational material is ensured, since the production rules apply to all levels of the semantic structure of educational materials. Automation of the process of creation of test tasks provides a significant reduction of time for the development of test tasks. The data contained in the model (headings, key terms, test tasks, relations) make it possible to carry out adaptive control of the level of knowledge.
