Abstract: The automatic processing of unstructured texts in natural languages is one of the relevant problems of computer analysis and text synthesis. Within this problem, the author singles out a task of text normalization, which usually suggests such processes as tokenization, stemming, and lemmatization. The existing stemming algorithms for the most part are oriented towards the synthetic languages with inflectional morphemes. The Uzbek language represents an example of agglutinative language, characterized by polysemanticity of affixal and auxiliary morphemes. Although the Uzbek language largely differs from, for example, English language, it is successfully processed by stemming algorithms. There are virtually no examples of effective implementation of stemming algorithms for the Uzbek language; therefore, this questions is the subject of scientific interest and defines the goal of this work. In the course of this research, the author solved the task of bringing the given texts in the Uzbek language to normal form, which on the preliminary stage were tokenized and cleared of stop words. To author developed the method of normalization of texts in the Uzbek language based on the stemming algorithm. The development of stemming algorithm employed hybrid approach with application of algorithmic method, lexicon of linguistic rules and database of the normal word forms of the Uzbek language. The precision of the proposed algorithm depends on the precision of tokenization algorithm. At the same time, the article did not explore the question of finding the roots of paired words separated by spaces, as this task is solved at the stage of tokenization. The algorithm can be integrated into various automated systems for machine translation, information extraction, data retrieval, etc.

Abstract: The subject of the study is the process of forming the parameters of the user interface that is being changed. The author considers the possibility of using neural network methods to process characteristics and classify the categories of user interfaces. To solve the problem studied, the structure of an artificial neural network based on a multilayer perceptron is modeled, the training set of data is prepared and the kit is used to train a simulated neural network. Based on the obtained parameters of the neural network, a mathematical model was constructed and analyzed to solve the problem in question, a study was made of the resulting data for various sets of input data that were not used in training the network. To form the training data set, simulate and train the neural network, the MathLab MathLab system and the Neural Network Toolbox expansion package are used, which allows building a neural network suitable for solving the tasks posed. The conducted research showed that the problem of classifying the parameters of the user interface by a set of input characteristics can be adequately solved with the help of a neural network of direct propagation based on a multilayer perceptron. The most important moments when using this solution are the choice of the architecture of the neural network being created and the preparation of a training data set for building a neural network

Abstract: The article presents description of the method of semantic editing and a overview of current research in this field. The overview is presented in terms of dividing the views of the software system into the abstract, editable, executed, stored and visual parts. Tools and methods that allow increasing the productivity of software development are always relevant. There are various integrated development environments (IDEs), which combine different methods to significantly increase the productivity of the programmer in comparison with the work without IDE. One of the promising methods is the semantic editing of the program code of the developed system allowing changing the abstract representation of the software through various editable views. The author concludes that currently there are no universal integrated software development environments with semantic editing of program code. The development of such environments could significantly increase the productivity of the programmer in comparison with the work without IDE due to the semantic editing and the function of the version control system that tracks not text changes, but changes in the abstract code model.

Abstract: The growth of a number of electronic devices and their capacities trigger the development of recommendation systems in general and adaptive interfaces in particular. Such systems collect information about user experience and analyze obtained data using the methods of machine-aided learning. Not ony the number of devices is growing, so is the number of users who often have different needs and demands. The author of the article pays special attention to the interface of USSD services. The purpose of the research is to develop an approach alllowing to decrease the average number of demands made by users while working with the text menu. To find a relevant solution, the author applied the methods of systems analysis and discovered a strong dependence between needs of each user and his/her context. Using the information about the execution context allowed to improve the existing methods and obtain better results. The author's approach is based on the two-stage clusterization: interface clusterization at the first stage and context clusterization at the second stage. To carry out testing the author used data collected during interaction with the users of USSD-services.

Abstract: The article studies features of technical and tactical training in team sports using information technology. The main arguments in favor of such learning technologies are demonstrativeness, interactivity, use of combined forms of presenting the information and implementation of self-directed learning that affects the quality of learning process. These features make it possible to create such conditions of the training process by which athletes can much quicker learn the patterns of movements with complex coordination structure unavailable in conventional organization of technical and tactical training. Technology of the technical and tactical training is implemented on the playing field with controlled light light-backlit defining the light zones. Some zones, highlighted, are forbidden for the athlete; they can be static or move around simulating opponents. Such zones prevent the movement of the athlete, simulating game situations. The athlete assess the simulated situation, predicts its development, chooses a rational path and moves along it with the ball to the free zone or passes the ball through the free zone to the opponent’s area or to another member of the team. Depending on the athlete's personal level the coach chooses a program that specifies the training mode and level of complexity. The technical and tactical training level of the athlete can be judged by the number of hits into the forbidden highlighted zone, by the ability to evaluate simulated game situation and predict its development, by the ability to use own technical and tactical skills. The technology can be used in technical and tactical training of teams in varying sports, specializing in football, hockey, handball, rugby, basketball and other team sports.
