Increasing of Semantic Sustainability in the Interaction of Information Processes
(2020) Kosikov, S.; Parfenova, I.; Ismailova, L.; Wolfengagen, V.; Исмаилова, Лариса Юсифовна; Вольфенгаген, Вячеслав Эрнстович
© 2020, Springer Nature Switzerland AG.Ordinary semantic network in use is based on the referencing of individuals in a constant mode. When modeling the interaction of information processes, there is a dynamic that requires a transient process. In this case, individuals can be dereferenced, which leads to a violation of the stability of the information system (IS). A dynamic model is proposed and, in particular, based on (after-became)-neighborhood of properties in the semantic network. There is a semantic Web, in which there is individual confluence, i.e. semantic vulnerabilities. A semantic secure solution is based on: (1) the semantic sustainability of interrelated information processes, (2) granulation of data-metadata objects, and (3) the generation of variable metadata objects. This is done against the background of the formation of “possible worlds” as a spectrum of evolving the events. There is a transformation of properties and an associated transition process, for which a means of ensuring sustainability is proposed.

Applicative Model to Bring-in Conceptual Envelope for Computational Thinking with Information Processes
(2021) Kosikov, S.; Wolfengagen, V.; Ismailova, L.; Вольфенгаген, Вячеслав Эрнстович; Исмаилова, Лариса Юсифовна
© 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.Computational activity is now recognized as a natural science, and computational and informational processes have been discovered in the deep structures of many areas. Computations in the natural world were present long before the invention of computers, but a remarkable shift in understanding its fundamental nature occurs, in fact, before our eyes. The present moment, in fact, is a transition from the concept of computer science as an artificial science to the understanding that information processes are abundant in nature. Computing is recognized as a natural science that studies natural and artificial information processes. All object constructions are considered as virtual objects, which are possibly combinators. They are connected by “combinatory glue” and form an applicative prestructure.

A Computational Model for Supporting Access Policies to Semantic Web
(2019) Kosikov, S. V.; Ismailova, L. Y.; Wolfengagen, V. E.; Исмаилова, Лариса Юсифовна; Вольфенгаген, Вячеслав Эрнстович
© 2019, Springer Nature Switzerland AG. The paper discusses a solution to the problem of data storage in a Web environment and providing access to the data based on their semantics. The problem involves restricting access to data in accordance with the description of the access rights for different classes of users. The information is interpreted in different ways according to the semantics assigned to users. Access policies are proposed as the main technical tool for describing access rights. The provided information is consistent with the semantic description of the user accessing the information. The semantic matching of descriptions of users and the data representation combines formal and informal moments and in general is of a cognitive character. The proposed solution is based on the use of data representation in the form of semantic networks. The solution has computational nature and involves calculating the value of the structures of a specialized control semantic network describing access policies. The solution is presented in the form of a computational model, which is based on the intensional logic. The constructions of the model include both a logical means of general type and specialized structures for control the degree of intensionality. The model provides calculation of construction values depending on the parameter - assignment point. The proposed method of parameter assigning provides the possibility of taking into account the semantic characteristics of users of different classes, as well as a number of other factors essential to support the semantic network (including the presence of different versions). The article offers the architecture of the instrumental complex to support access policies that support the developed computational model, and describes its main components. The components were tested in solving practical problems in the field of jurisprudence to ensure the manipulation and visualization of concepts.

Constructing generator of words of context-sensitive language on example of typed λ-calculus
(2022) Slieptsov, I. O.; Wolfengagen, V. E.; Kosikov, S.; Вольфенгаген, Вячеслав Эрнстович
The given paper considers a problem of generating words of a context-dependent language. It reviews the application of the problem to the unit testing of functions, examines in detail the use of generators in property-based testing. The context-dependent language of О»-calculus with a simple type system О›в†’ is considered, and the problem is refined up to generating О»-terms with the given type within the given context. The article proposes a generation method that was implemented using the combinators of the fast-check library, which provides property-based testing in JavaScript.

Cognitive System for Traversing the Possible Worlds with Individual Information Processes
(2022) Kosikov, S.; Dohrn, S.; Wolfengagen, V.; Ismailova, L.; Вольфенгаген, Вячеслав Эрнстович; Исмаилова, Лариса Юсифовна
© 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.In this work, an individual process, or for short, an individual is selected, and the “history” of its transformations is traced, depending on the scenario. Scenario is considered as the restriction imposed on the behavior of individual. States, or separate scenes, are achieved by possible worlds, and transitions between worlds are given by the relation of reachability, or evolvent. The evolvent restricts a transition from one stage of knowledge to later stages. In fact, in this work, the only preliminary work has been done to study the dynamics of the individual and a leading example is formulated. Its formulation gives rise to the induced commutative diagrams in a representative functor category. The mathematical apparatus involved is based on the variable domains and the functor category that represents them. Its purpose is to develop a certain intuition of semantic modeling, and then, if possible, to form a cognitive system. Some limited semantic models have been implemented and are undergoing further practical testing and improvement.

Dynamics of Recognition of Properties in Diagnostics
(2020) Kosikov, S.; Ismailova, L.; Wolfengagen, V.; Исмаилова, Лариса Юсифовна; Вольфенгаген, Вячеслав Эрнстович
© 2020, Springer Nature Switzerland AG.The issues of processing semantic information for diagnostic studies are considered, in which, with the advent of personalized medicine, the task of ensuring efficiency and accuracy has come to the fore. The solution of such problems is associated with the need to recognize the properties of the samples, which is done by experts/crowdsourcers using the means of semantic modeling. In this regard, the analysis is subject to communication (1) level of knowledge with (2) forms of information processing and with (3) levels of abstraction. For this, a dynamic semantic model is developed and applied that can take into account such parameterization.

A Semantic Model for Indexing in the Hidden Web
(2021) Kosikov, S.; Ismailova, L.; Wolfengagen, V.; Исмаилова, Лариса Юсифовна; Вольфенгаген, Вячеслав Эрнстович
© 2020 Elsevier B.V.. All rights reserved.We argue that that the use of the Carnap - Bar-Hillel principle of indexed expressions provides a suitable cognitive model to undergo the spread of information processes in the Semantic Net. To understand the stratification of the net into the surface Web and the hidden Web, a model structure is proposed that provides navigation through the net as a whole. For logical expressions, a relativized evaluation map is given, which is parameterized by the indexing system. It is allowed to use concepts that are generated using partial functions, the variables of which run over the range of possible individual information processes. A generalized operator providing virtualization is presented for individuals. The process is accompanied with the dynamic generation of Web-pages, which triggers their indexing. This way they are thereby transferred to the surface layer of the network. A commutative diagram is proposed that establishes a cognitive model of semantic constructions of variable domains, the connection of virtual individuals with actual ones which corresponds to transitions over the stages of knowledge. The knowledge stages are modeled by indexing systems.

Cognitive Features for Stability of Semantic Information Processing
(2020) Kosikov, S.; Wolfengagen, V.; Ismailova, L.; Вольфенгаген, Вячеслав Эрнстович; Исмаилова, Лариса Юсифовна
© 2020, Springer Nature Switzerland AG.The issues of semantic information processing are considered. The central idea of information in the modern world is still an elusive concept. It is known that information must be quantified, at least in terms of partial ordering, to be additive, stored and transmitted. However, besides all this, there is no clear idea about its specific nature. The development of cognitive technologies poses the question of forms of knowledge representation: can the “stage of knowledge” be fully and faithfully analyzed in terms and forms of information processing at some level of abstraction? In other words, the analysis is to relate (1) the stage of knowledge with (2) forms of information processing and (3) levels of abstraction. Among the problems posed by the development of information technology, one of the key roles is played by the information semantics. The most significant open problems imply the development of research on a new basis in the following areas: providing data substantiation (how data can acquire meaning); ensuring the truth of the data (as meaningful data can acquire true values); building an information theory of truth (can information explain truth); constructing information semantics (can information explicate a value).

Mutable Applicative Model to Prevent Entanglement of Information Processes
(2020) Kosikov, S.; Maslov, M.; Wolfengagen, V.; Ismailova, L.; Вольфенгаген, Вячеслав Эрнстович; Исмаилова, Лариса Юсифовна
© 2020, Springer Nature Switzerland AG.A system for detecting and possibly preventing undesirable changes in the properties of objects within information system (IS), leading to a violation of the semantic consistency of information, unstable functioning of the IS and, ultimately, loss of its operability, is proposed. The modeling tools is a means for detecting and preventing the destruction of the semantic integrity of data/metadata objects in IS. The basis is the original computational model, which increases the sustainability of semantic nets, while giving them more opportunities to reflect the dynamics of the problem domain. This gives rise to IS with increased expressive capabilities, supporting the evolving semantic nets, integrated with the Web. Mechanisms for modeling the dynamics of concepts and the computational model contribute to overcoming the contradictions that exist for today in the application of semantic information technologies.

Superimposing semantic mesh to prevent information processes entanglement
(2020) Kosikov, S.; Dohrn, J.; Wolfengagen, V.; Ismailova, L.; Вольфенгаген, Вячеслав Эрнстович; Исмаилова, Лариса Юсифовна
© 2020 The Authors. Published by Elsevier B.V.In this paper, we study the problems of extracting concepts from data and introduce the notion of deviation of concepts. A wireframe model structure is established in the form of a semantic mesh, which allows you to control deviation by establishing the spectrum of possible hops on the way to achieving the generic concepts. The use of scaling to reflect the dynamics of information processes that represent data is shown. By varying the degree of generality of the scales used, the desired level of abstracting the semantic mesh is achieved. A representative example of a stepwise transition from a specific individual semantic mesh based on using the content of a subject area to an abstract semantic mesh that controls general information processes is constructed. The resulting conceptual model supports a scaled conceptual dependency on the generic and derived concepts. To map on a generalized semantic mesh with nodes in the form of variable domains, a mapper-adapter is required.
