In this paper, the process of developing an ontological model of knowledge of state control bodies in the field of quotas for the extraction of aquatic biological resources is considered. The need to develop this model arose due to the insufficient level of automation of knowledge extraction from data collected and processed manually from eighteen territorial departments of the Federal Agency for Fisheries. Insufficient speed of collecting and processing data on the current level of industrial production of aquatic biological resources may cause incorrect planning during the subsequent distribution of catch quotas, which may lead to a decrease in biological diversity in the reservoirs of the Russian Federation with the subsequent loss of types of aquatic biological resources.Method. The study used methods of analysis of theoretical and regulatory documentation, analysis of statistical data, as well as secondary data analysis.Result. An object ontological model of knowledge of state control bodies in the field of quotas for the extraction of aquatic biological resources has been developed.Conclusion. The developed ontological model makes it possible to accelerate the extraction of knowledge from aggregated data on the level of distribution and development of quotas for catching aquatic biological resources, and also serves as the basis for creating a full-fledged information system for accounting for the extraction of aquatic biological resources and monitoring their population.","PeriodicalId":202454,"journal":{"name":"Herald of Dagestan State Technical University.

The purpose of the work is devoted to the development and description of the mathematical model of the Chinese character recognition system, taking into account all the features of writing the Chinese language. The Chinese language learning app with character recognition module can help you replace a native speaker or home teacher for self-study. However, the developed software applications are based only on the creation of a neural network and cannot provide recognition, taking into account all the features of the language, which is so important when studying, therefore this topic is still relevant.Method. The neural network training model is based on the use of artificial neural networks using the backpropagation algorithm.Result. The article presents a software implementation of a system for teaching Chinese characters, taking into account the peculiarities of writing, the direction of each feature and its exact definition, taking into account the correct sequence and location in the character, as well as controlling the length of the features.Conclusion. Each of the writing features is an integral part of learning a language, since it can not only completely change the meaning of the written hieroglyph, but also help the learner to memorize the hieroglyph in a structured way, giving him a clear structure and algorithm of actions for writing the hieroglyph. When errors are detected when writing, the system will indicate to the user where exactly and in what area the error was made, what feature of the language he did not take into account, and attention should be paid to it.","PeriodicalId":202454,"journal":{"name":"Herald of Dagestan State Technical University.

The flow of detected vulnerabilities of the automated system was considered as an incoming flow of applications. The system, due to the possibility of detecting many vulnerabilities in a short time, has a queue of vulnerabilities. Information security specialists responsible for eliminating vulnerabilities in this system are considered as service channels.
