Abstract: The object of research is neural networks, the VKontakte platform, the Telegram messenger, the Python programming language and its libraries, and a block diagram of a computer system model. The subject of the study is a computer technology for detecting extremist content in text form and specific groups containing it on the VKontakte social network. The authors consider in detail the structural scheme of the computer system model, the functional modules included in it, and illustrate their interaction. The paper uses a pre-trained model designed for processing the Russian language, and provides conditions for ensuring high accuracy of recognition of illegal content without signs of retraining. The paper presents the results of checking the test data confirming the operability of the computer system. The proposed prototype of the computer system ensures its integration with the Telegram messenger, which increases usability and facilitates the process of generating queries and reports. The novelty of the research lies in the creation of a prototype of a computer system for searching and detecting extremist messages on the VKontakte social network using the Python programming language and the VKontakte API programming interface (VK API). The basis of the prototype computer system is a neural network that works with the Тгаnsformers and Тоrch. A special feature of the computer system is the ability to analyze messages on a social network and subject them to binary classification for the content or non-content of illegal information in messages. The main conclusions of the study show the efficiency of the system, the simplicity and convenience of its use, the possibility of detecting illegal text content. A distinctive feature of the prototype is the ability to detect illegal content presented using slang expressions.

Abstract: The subject of the study is the classification of special equipment of the internal affairs bodies, the grounds for its classification, the requirements for the names of groups of equipment. The object of the study is the normative legal acts of the Ministry of Internal Affairs of Russia, containing information about the concept of "special equipment of internal affairs bodies", about its division into groups reflecting the system of scientific and technical information adopted by the Ministry of Internal Affairs, as well as scientific works devoted to classification as a method of scientific research, educational literature in this subject area. Using scientific methods of cognition, such as induction, deduction, analysis, synthesis, classification, the authors discuss the concepts of "special", "technique", "special technique of internal affairs bodies", contradictions in regulatory legal acts reflecting the classification of the above-mentioned technique.
The novelty of the study lies in clarifying the concept of "special equipment of internal affairs bodies", identifying criteria for attributing technical means to this group. The choice of a universal basis for classification, such as the purpose of technology, is justified. The division of special equipment of internal affairs bodies into groups has been carried out and their names corresponding to the terminology of state standards and departmental regulatory legal acts have been proposed.
The main result of the work is the development of a draft structure of the List of samples (complexes, systems) of special equipment accepted for the supply of internal affairs bodies of the Russian Federation. It is proposed to supplement its content with the sections "Special equipment", "Conventional equipment", "Equipment" and adjust the name.

Abstract: The subject of the study is the classification of inspection and search equipment. The object of research in the work is the tactical and technical characteristics of various samples of inspection and search equipment, the features of its design, the principles of operation of the devices. The paper discusses such classifiers as the type of the detected object, the design features of the product, the specifics of the impact on the surrounding space, the physical principle of operation. The author pays special attention to the search, formulation and discussion of classification features that allow us to fully characterize not only the purpose and design of a specific inspection or search technical means, but also the principle of operation, in order to form a single conceptual apparatus in the subject area.    The main results of the study are a comprehensive consideration of the classification of inspection and search equipment, the formulation of the names of groups of inspection and search equipment, based on its principle of operation. Within the framework of individual groups, an additional division of equipment into subgroups is proposed, which allows even more accurately characterizing its capabilities.
The novelty of the research also lies in the discussion of the advantages and disadvantages of classifying signs of inspection and search equipment, in the proposal of a classification scheme based on the physical principles of the devices. For a more complete understanding of the developed classification, the author provides examples of search and inspection devices of different types according to the developed criteria.
