The strategic documents at European and national level set as a main goal for education the introduction of elements of artificial intelligence in the various educational levels and forms of training in a way appropriate for the learners. In the last two years, experimental training in artificial intelligence in high school has been implemented in Bulgaria. The report examines some problems and challenges in organizing and conducting this training in different types of schools, specialties and classes. Some guidelines are outlined and ideas for creating an appropriate curriculum and learning resources in the field of knowledge structuring and semantic modelling are shared. An approach to teacher and student training is proposed. The authors share their experience in teaching teachers and students and analyse the results of surveys and tests.

The report examines an approach to standardized presentation and virtualization of Bulgaria's cultural, historical, and natural heritage sites. Ideas and experience in using this knowledge in the teaching of various subjects in school education are shared.

The article presents an approach for the application of digital libraries, including a network of ontologies and structured databases in the education of school students in literature, history, geography and biology. The general architecture of a multi-agent platform based on the reference framework of the ViPS (Virtual Physical Space) system, which is being developed in the DeLC Laboratory of the Plovdiv University Paisii Hilendarski“, will be considered. The information and data in this platform are maintained by a hybrid structure of ontologies and databases, with the designed services maintained by intelligent agents and personal assistants. Through interaction between these intelligent components, functionalities are modelled, such as: conducting virtual tours in the teaching of different subjects; automatic generation of questionnaires, tests and surveys; development of project assignments; game-based learning; group assignments, etc. These functionalities and services are aimed at classroom training as well as interest clubs.

The preservation and dissemination of knowledge about cultural, historical, and natural sites in Bulgaria is extremely important. In this regard, the Faculty of Mathematics and Informatics of Plovdiv University is developing a project related to the implementation of an intelligent tourist guide, which, according to the tourist’s criteria, generates virtual or real tourist routes. The article will present part of the knowledge base of the tourist guide, namely an ontology that describes the richness of Bulgarian literature. The structure of the ontology, the basic axioms, and dependencies between the basic concepts, as well as the identities of the individual concepts in the ontology are presented. Keywords: Ontology; Bulgarian Literature; Intelligent Tourist Guide

The article discusses the application of digital libraries, including a network of ontologies and structured databases, in the education of students in secondary schools. The multi-agent platform of VES (the Virtual Educational Space) is presented, based on the reference architecture of ViPS (the Virtual Physical Space), which is being developed in the DeLC (the Distributed e-Learning Center) laboratory of the University of Plovdiv “Paisii Hilendarski”. The information and data in VES are supported by a hybrid structure of ontologies and databases, as the designed services are supported by intelligent agents and personal assistants. Through the interaction between these intelligent components, some functionalities are modeled such as conducting virtual excursions in the teaching of various school subjects, automatic generation of tests and surveys, development of project tasks, game-based training, etc.
