The article is devoted to the topical issue of identifying information threats in virtual communities of social networks and mechanisms for counteracting such threats. The process of organization of monitoring and content analysis of virtual communities in social networks is studied. The technology of detecting information threats of virtual communities in social networks and methods of their assessment have been developed. An approach to finding pages of discussions on social networks based on the Louvain method is proposed. The technology of determining the degree of information threat of the virtual community in social networks and ways to counteract the information threats of the virtual community have been developed.
The article examines the methods of counteracting the negative information impact through virtual communities of social networks. The general recommendations on construction of model of system of monitoring of virtual communities of social networks, using already existing scientific researches are offered. Three strategies of influence on the structure of the information environment of virtual communities and their shortcomings are investigated. The analysis of the result of using the considered strategies on already existing researches is carried out. Graphs of changes in the indicator of information threat of the process of functioning of the virtual community depending on the strategy of influencing the structure of the internal information environment are obtained. The structure of the sequence of development of methods and algorithms for assessing information threats of virtual communities in social networks is considered.
