An effective quality control of textual information on the basis of statistical redundancy in distributed mobile IT systems and e-applications

Abstract

The architecture of uniform information space of Republic of Uzbekistan by a hierarchical principle on the basis distributed mobile IT systems is stated. For the information space of regional management which is formed as set of the distributed databases and knowledge, storehouses of the information, computing centers, managing systems, and also applied Internet-portals and systems for representation of modern e-services the task of providing of reliability of inputting, transfer and processing of the information of a various nature and format is put and solved at a level of the users of network services of an applied level (Applied, Presentation, Session levels of OSI model). The algorithms based on principles of statistical and dictionary coding are developed for the control of the information reliability at the expense of statistical redundancy. There are used the schemes of coding by methods of Huffman, Lempel-Ziv-Welch, transformation of Burrows-Wheeler and arithmetical coding.
