Annotation: The study is devoted to the analysis of the deficits of students of a pedagogical university in preparation for volunteering at school. The study of the causes and factors that reduce the success of educational activities in the field of volunteering by future teachers in their interaction with schoolchildren is conducted. As a result of interviewing and surveying students of pedagogical specialties, deficiencies were identified in the field of personal motivation of students for volunteer activities and organizing it at school, which can negatively affect their further practical work in this aspect in the future. Promising areas for overcoming the identified difficul- ties in the field of training students of a pedagogical university are identified. These include the development and implementation of a special educational course in the system of professional training of future teachers to develop the skills of students to organize volunteer activities at school, the inclusion of methods of motivating volunteering in the program of this course.

Annotation: The article explores the implicative information relations in the information field. The ambiguity of implicative information relations makes it possible to use them to build a universal methodology that can describe processes, transitions or relationships in different contexts. A technique for constructing implicative models for describing relationships and processes based on the formal apparatus of implications is proposed. Examples of the con- struction of implicative information structures are given and their interpretation is given. The difference between binary and trinary implicative constructions is shown. Implicative information constructions applicable for causal analysis are considered. The content of the antecedent, sequence and consequent in the trinitarian implication is revealed. Categorical transitions are described using implicative models. The application of implicative models in qualitative analysis is described. A new concept of “parametric implicative model” has been introduced. The principle of formal interpretability of the parametric implicative model is demonstrated, which allows for a comparative analysis of situations and objects. In this way, it helps to streamline the analysis procedures and substantiate the decisions made.

Annotation: The article explores implicit knowledge in information retrieval. There is a tendency to increase the volume of information, including in information networks. This trend motivates research in the field of information retrieval. An increase in the volume of information leads to an increase in hidden knowledge and information uncertainty. The taxonomy of the reasons for the inadequacy of the search in the information network is given. These reasons are divided into objective and cognitive. The difference between morphological and semantic search is shown. A set-theoretic model for describing the search for information and its results is proposed. Three main types of information retrieval are described. The difference between the search for information and the search for knowledge is shown. The qualitative difference between ontological and traditional information search is shown. The reasons for the appearance of implicit knowledge in practical activities and scientific research are shown. A formal description of the ontological search, including a component of implicit knowledge, is given. The criteria for the presence of implicit knowledge, which can be obtained through an ontological search, are shown. The results of this study contribute to the development of information retrieval methods, ontological search and the identification of implicit knowledge.

Annotation: The article reveals the importance of applying the approach of career-guidance tours in training specialists in the direction of “Technosphere Safety”. Professions in this area are associated with emergency situations and require the acquisition of special competencies. The article considers the principles of creation and functioning of professionally oriented volunteer organizations, on the basis of which career-guidance tours are carried out for students and advanced acquaintance with the practical side of the chosen specialty is realized. The important role of integrating informal activities of students into the educational program in the direction of training is noted. An empirical study was conducted based on a survey among students. The method of comparative analysis of the obtained empirical data was used as a diagnostic tool. A comparative assessment of the qualitative and quantitative characteristics of employment of university graduates was made. High efficiency of applying the approach of career-guidance tours in training specialists in technosphere safety is noted. The results obtained can be implemented in the development of educational technologies, pedagogical methods and teaching methods at all levels of professional education.

Annotation: The article explores the category of “correspondence” in the field of information field and information modeling. The category of “correspondence” has a multifaceted nature of existence in terms of form, content, and relation- ships between objects. Correspondence can be a function, an image, a computational or logical operation, a way of transmitting information units, etc. Correspondence can be considered as a relationship, as a property between two entities, as a result of comparing information objects, as an assessment of the results of an infor- mation search. Correspondence can be procedural, semantic, morphological, structural, etc. Different types of correspondence determine the relevance of its research. The article presents a systematics of correspondences according to formal and applied features. The content of the correspondences of formal and applied meaning is revealed. Generalized properties of the category “correspondence” and its complement “nonconformity” are presented in terms of set theory and mathematical logic. The difference between full and partial correspondence is shown. It is shown that an important category of correspondence is ontological correspondence, which al- lows the formation of knowledge, and information correspondence, which is a composite correspondence in the information field. The developed foundations of the theory of correspondence between information objects are aimed at expanding and clarifying the formalized procedures of information retrieval and information modeling, and identifying implicit knowledge.
