The purpose of the work is to investigate clustering, correlations, repeatability and network properties of natural and random texts and digital images; to find out their mutual connections; to propose algorithms for establishing semantics and noise of texts and images; to apply the studied phenomena to search for keywords in natural texts. Research methods: mathematical statistics, software-algorithmic approaches, empirical and network methods, numerical modeling. Results obtained. Methods of randomization and study of network parameters of texts and digital images were developed and implemented in software. New approaches to distinguishing informative and noise images were proposed. Random texts of different types and natural texts in different languages ​​were studied. Based on network properties and correlations, a method for determining keywords in texts was proposed. The phenomenon of irreversibility of natural texts is studied and a comparison is made with the main random models. Product Description popup.authors Izhyk Oleh B. Horon Bohdan I. Dovhan Ivan Ya.
