DISTRIBUTED INFORMATION SYSTEMS ON THE BASE OF NETWORKS WITH LOW CHANNEL CAPACITY.

• N. A. Grusho   IPI RAN, info@itake.ru

Abstract:  The problem of building a semantic encoding for distributed network-based channels with low bandwidth is discussed. On the example of the trade network, it is shown that the compression of semantic information in the specified time intervals makes it possible to reduce the requirements to the channels on the order.

NEW FEATURES OF SELF-PROPAGATING MALWARE.

• M. V. Levykin   IPI RAN, de_shiko@yahoo.com

Abstract:  According to the research of malwares such as \worm" stuxnet and \bootkit" TDL/TDSS, the following features appeared: modern malware are the multiagent systems with a complicated structure on the different levels of operating system. Such multiagent systems may consist of the following components: concealment, communication, operations, distribution, etc. Interface between the systems agents is of particular interest.

• V. Umanskiy   Close Corporation "IntexGeoTrans"

Abstract: In geographical information systems (GIS), where quality management of geodata depends on specificity of spatial objects, the problem of the consistency gets additional complexity. In the paper, some features of a spatial consistency of geographical data sets in the vector format are described. These features are essential at elimination of mistakes of display and classification. Three types of errors that affect the corresponding types of a consistency are considered: structural, geometric, and toposemantic. Each type of error require special procedures for verification and correction. These procedures are presented in the form of a common framework.

• A.G. Matskevich   IPI RAN, xmag@mail.ru

Abstract:  The techniques for improving the lexical-morphological analysis of the semantic- oriented language processor which carries out the extraction of knowledge from the natural language texts are considered. Methods and means to eliminate uncertainties in the allocation of text tokens and sentences, as well as methods of combinatorial and syntactic analysis to eliminate morphological homonymy are proposed. The methods give possibilities to improve the semantic linguistic processor which extracts knowledge structures from natural language texts and restores implicit information.

SEMANTICMETHODS FOR IMPLICIT INFORMATION DISCOVERY .

• I. P. Kuznetsov   IPI RAN, igor-kuz@mtu-net.ru

Abstract:  Development of semantic linguistic processors, which extract knowledge structures from natural language texts is connected with identification of implicit information. This problem is considered as detection of new properties of objects in Knowledge Base. The methods of such identification based on analysis of knowledge structures are suggested. As an application, the problem of identification of roles and functions of persons involved is considered based on their descriptions in the documents of criminal police.

APPROACHES TO LEXICAL AND SEMANTIC MODELING AND LINGUISTIC RESOURCES OF INFORMATION SYSTEMS.

• O. S. Kozhunova   IPI RAN, kozhunovka@mail.ru

Abstract:  Up-to-date methods and approaches to semantic modeling are analyzed, namely, in the publications of such prominent specialists in the field as N.N. Leontjeva, E.V. Paducheva, J.D. Apresyan, R. Jackendoff, J. Sowa, and others. Some of the linguistic resources (integrated into information systems) with semantics oriented features and other language-specific attributes are considered. Besides analyzing and reviewing of the existing approaches and resources, some suggestions and additions are given by the author, including the approaches of the artificial intelligence techniques and JSM (John Stewart Mill) method formalisms.

IMPACT-FACTOR MODEL IN LEGAL REGULATION SYSTEM OF SCIENTIFIC ORGANIZATION ACTIVITY.

• G. V. Lukyanov   IPI RAN, gena-mslu@mail.ru

Abstract:  The paper deals with a new indicator of effectiveness of scientific organizations and, namely, the impact-factor of publications in \Web of Science" of employees in a scientific organization. It has been proved that the new interpretation of this indicator boils down at the best to the average value of the traditional impact-factor of several journals, and at the worst to the impact-factor of a single journal.

ABOUT THE NEED AND POSSIBILITIES OF A UNIFIED DEFINITION OF INFORMATION.

• I. Gurevich   IPI RAN; LLC "HETNET Consulting," iggurevich@gmail.com

Abstract:  To create "Science of Information," we must use single, unified, unique definition of "information" concept. About 10 billion years ago, there was no life in the Universe. Information existed only in the formof physical heterogeneities (elementary particles, atoms, molecules, etc.) which possess information properties of the primary (first) order - in particular, they contain certain volume of information. Its existence did not depend on an observer existence. An observer appeared several billion years ago and gave new properties (of the second order) to information.
