The publication explores the potential of wiki encyclopedias in addressing the challenge of constructing thesauri for educational courses. It highlights the advantages of utilizing semantic elements from these wiki platforms in the professional development of adult educators.

This article addresses the development and processing of an andragogue profile designed for integration into the adult learning ecosystem. In this context, the andragogue profile is considered as a key element ensuring optimal interaction between the andragogue and the learner. The andragogue facilitates individualized learning conditions by providing a flexible study plan and leveraging the full potential of semantic technologies. The authors emphasize the importance of semantic personalization of the learning process through the creation of personal learning trajectories (PLTs). These trajectories account for diverse learner needs and capabilities, defining individualized interaction plans between the learner and the andragogue. In this research, we propose the method of constructing an extended andragogue profile that incorporates additional characteristics related to various aspects of andragogue`s skills, knowledge and research specialization. These characteristics can be used to develop PLTs for adults on various stages of their lifelong learning (LLL). The extended profile integrates structure elements from both teacher and researcher profiles, supplemented by specific parameters of andragogue`s activities by modeling of characteristics influenced the PLT construction, interaction with learners, and other critical aspects of the educational process. Utilizing this profile can ultimately improve the quality of learning. For a multi- criteria evaluation of the andragogue profile, we apply the Saaty Analytic Hierarchy Process (AHP) method to determine the weighting coefficients of individual parameters such as professional competence, psychological profile, technological literacy and motivational characteristics.

Modern online encyclopedic resources provide actualization and integration of domain terminology, unambiguous definitions of its basic concepts and the semantics of relations between them agreed by experts. The use of encyclopedic content in the educational process allows to update the terminology of learning courses, correctly define connections with other disciplines and concepts, agree on definitions, etc. This content has to be protected from unauthorized changes, but as a result, third-party users do not have access to the elements of semantic structuring of such resources. Therefore, it is necessary to find a compromise between the resource code openness and the security of the encyclopedias content in order to expand their functionality and allow to obtain from them information pertinent for certain practical tasks. For this purpose, we propose to select clearly those elements of semantic markup that are necessary for search and further processing of the content of a certain type, to add these markup elements to pages of corresponding encyclopedic articles and formally define their values. We propose to expand the existing set of semantic properties, but display for users only a certain subset of the names and values of these properties. In this work, we consider this problem on example of metadata building for learning objects based on the transformation of the protected content of encyclopedic articles aimed at their use for the generation of individual educational trajectories. We have to define some minimal set of metadata that is sufficient for problem solving. For this purpose, we analyze the most common standards of metadata representation for learning objects and other important elements of the educational process. Based on this analysis, a set of properties of learning objects that can be obtained from the pertinent encyclopedia article (automatically, semi-automatically or with the help of domain experts) is selected.

The article substantiates the expediency of using semantic technologies as a tool for professionalization of andragogues. Authors determine the basic preconditions that have an influence on the effectiveness of information support for the training and professional activity of andragogues. The clarity of the terminological apparatus in the field of learning and education of adults provides the basis for the further development of a formal model scheme of this subject area that interoperably fixes the various relations between concepts at the level of semantics. The online repository of relevant information resources that supports semantic structuring and unified integration of content provides convenient access to knowledge in the subject area. The availability of an appropriate set of advisory and retrieval services provides personalized information support for the training of andragogues using the content of this repository. The authors proposed the AndraMedia advisory system that is intended for process of informational support of the professionalization of andragogues. It ensures the integration with other intelligent advisory systems, open educational resources, online encyclopedias, ontologies, consulting chatbots and various external knowledge bases. AndraMedia is based on the Semantic Web standards of knowledge representation and processing. Ontological model of AndraMedia system formalizes the relations between the main objects and subjects of the domain of andragogues professional training. The use of pertinent ontologies provides an unambiguous interpretation of the semantics of information resources and their integration with semantically enhanced wiki technologies used to structure content and to search it at the semantic level. The software implementation of the repository is based on MediaWiki and its SemanticMediaWiki plugin.

We aconsidernalyse the use of ecosystems paradigm for modeling the learning process that takes into account the specifics of adult students and analyse service-oriented approach for representation of andragogue activities. We research existing ecosystems developed for modelling of software design and learning process and select their components that can be used into adult learning. We propose to use ontological analysis to create a formal model of the adult ecosystem. Ontology of this ecosystem defines explicitly relations of its biotic and abiotic components and provides the basis for descriptions of the semantics of intelligent services used for support services of andragogue professional activities.

We consider actual trends in use of semantic technologies for development of the Web-oriented advisory software. Requirements and expressiveness of knowledge representation in this domain cause use of ontological knowledge model, and the Semantic Web standards and tools provide the technological foundation for creation of intelligent advisory applications that use external ontologies as sources of domain knowledge. Personification of advisory services needs in analysis of learning outcomes of informal and non-formal learning, and therefore we propose method of their formalization with use of background knowledge about with classifications of professions and qualifications in agricultural domain. This method is based on matching of semantic properties of information objects with different structure represented by atomic competencies. Services provided by advisory system are considered from the point of view of semantic technologies. Proposed approach is used for development of applied advisory system AdvisOnt aimed to combine the market of educational services with the labor market. AdvisOnt characteristics satisfy requirements to distributed semantic application.
