Methods of extension of abilities of text models’ semantic analysis

Methods of extension of abilities of semantic analysis of text models by introduction of additional semantic parameters, which come out of basic semantic parameters are researched. The structural components of models are reviewed and they are a base on which methods of extension of abilities of of text models analysis are researched. Basing on use of structural components of text models external semantic parameters are introduced, which also extend abilities of analysis of those models

Using text models in systems of control of social objects

This work introduces a method of building and using text models for the analysis and control of social objects. Social objects are groups of people united in informal organizations based on common interests and goals. The main tools to control social objects are information flows used by mass media. We examine different ways of using semantic parameters to analyze text models. This work contains research of implementation methods to monitor currently used social Internet networks and to provide feedback between the social objects and the control system

Methods of forming information streams and their interaction with text models

Analysis of interaction IPi with TMi is made, types of modification of TMi, which are made under influence of IPi are researched. It’s shown that synthesis of IPi with TMi is made on different levels of abstract reflection of interacting components. This allows ensuring correct transformations which take place in TMi, during implementation of processes of synthesis IPi with TMi. Beside semantic parameters and their values imagination about priorities which characterize separate components of text models is introduced. Such extension allows better taking into account of semantic of separate text components during making processes of synthesis of IPi with TMi, which leads to increase of abilities of adequate description of social objects by means of text models

Using text models in navigation

In this work are described and researched methods of protection of navigation system from unauthorized attempts to substitute trajectory of moving objects, guided by radio or satellite. The proposed methodology to detect such interference in the operation of the navigation system is based on the use of data for historical, located on the premises trajectory

Synthesis of text models with information streams

The methods of synthesis of text models with information streams are researched. In the process of functioning of system of text models, which model systems of social objects the following are implemented: analysis of models of monitoring of information means, used by social objects, control of adequacy of models to objects and objects management. The synthesis of text models with information streams is implemented basing on use of semantic parameters. In process of text forms synthesis of models description and information streams appears necessity to output new text fragments, reflecting synthesis result. Such output processes are procedures based on use of logical schemas and grammar rules

Peculiarities of use of speech acoustic environment while embedding into it of hidden message codes

The problems of embedding of message codes into Acoustic environment of speech are researched. The peculiarities of speech perception by human hearing are analyzed. As an example of acoustic Messager environment and codes of hidden messages embedded into it is reviewed a channel of mobile Communications in the part of transformations which are implemented with acoustic signals. Approach to build a model of process of transmission of speech via non-linear channel basing on imagination about speech signals spectrum is developed. The proposals on methods of use of such models for analysis and interpretation of distortions of signals made by transformations, implemented in example channel are presented

Hiding data in text environments and their parameters

In this study, the parameters have been developed, characterized by the invisibility level of the message, which is embedded in a text environment, and methods which determine the values of these parameters. Also a review of the system composition of steganography, which is oriented to the use of text digital environments. Also included is the concept of semantic vocabulary of digital environments and text messages. Were also made analysis methods for implementing messages, depending on the fit of these dictionaries
