  The methodology of automatic detection of the event basis of information
operations, reflected in thematic information flows, is described. The
presented methodology is based on the technologies for identifying information
operations, the formation of the terminological basis of the subject area, the
application of cluster analysis with cluster centroids, determined by analyzing
the terminology of the information flow. The clusters formed in this way
reflect the main events occurring during the information operations and reveal
the technique for their implementation.
