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.

Annotation: The article is focused on the study of geoinformation morphism in the geoinformation field. Despite the actual application of this approach and method, theoretical studies in this area have not been conducted. Geoinfor- mation morphism and categorical morphism have similarities and differences. Geoinformation morphism is a morphism of spatial transformations. Geoinformation morphism makes it possible to link logical relations, spatial relations, categorical relations and functional connections into a single analytical complex. The content of geoinformation morphism is revealed. The analogy between the logical square and the commutative diagram from category theory is shown. The relationship of geoinformation morphism with information morphism is shown. The content of three types of geoinformation morphism is revealed: bijective geoinformation morphism, injective geoinformation morphism, surjective geoinformation morphism. The qualitative difference in the tasks solved by these types of morphism is shown. Three types of geoinformation morphism complement each other and allow solving problems of spatial transformations. Recommendations are given for the development of the direction of research of geoinformation morphism.
