THE METHOD OF DATA EXCHANGE MANAGEMENT IN AUTOMATED INFORMATION SYSTEMS WITH SEMANTIC ANALYSIS OF TRANSMITTED INFORMATION ELEMENTS
- M. M. Gershkovich

The article proposes a method for managing the transmission of data elements between nodes of a geographically distributed automated information system (AIS) aimed at the fastest delivery of the most valuable information to the user in situations where a queue of data packets appears in the communication channel. The concept of an information object (IO) is defined as a set of characteristics of some entity. The concept of a logical data block is introduced as a combination of logically related characteristics of an IO or event. The composition of the logical block can be set by an expert depending on the content of the data in the AIS and on the tasks solved by users. A method for assigning priorities to logical data blocks during transmission over communication channels depending on the semantic content is described. An algorithm for quantifying the value of a logical block and changing the value of information over time is presented.
