  The absence of the efficient methods for the design of the information
sources impact network does not allow defining the influence of the information
sources on one another accurately and detecting the primary sources of the
information spreading. The work represents a new approach - Temporary
Horizontal Visibility Graph (THVG) method, which is based on the HVG algorithm
modification. This method allows building the information sources impact
networks and making the assumptions about the primary sources of information.
Obtained method uses sources rating in data flow analysis. It is more effective
than the usual Horizontal Visibility Graph design method in the following
criteria: F-measure - by 7-9%, completeness - by 7-10% and accuracy - by 6-8%
more effective.
