Аннотация:The paper represents a part of the global research on antisocial speech behavior by linguistic diagnosis of social network interaction on the Russian segment of the Internet with thematic focus on socio-cognitive deprivation factors. A sub-corpus of annotated polylogic items is described. The formation of the corpuses was aimed at the acquisition of objective experimental data on the current state of social network discourse existing at present on Russian segment of the Internet. Particular attention was paid to the speech / discourse / texts with negative (destructive) pragmatic orientation related to the manifestation of multifactor deprivation in written speech activity. The described sub-corpus is a collection of specially annotated independent discursive items that are polylogic items (polylogues) with isolation of referencethematic clusters related to the semantic field “political transformations”.The communicants are Russian-speaking users of such public social networks as “VKontakte” and “Livejournal”, as well as users commenting on news reports on the websites of news agencies and online media. The annotation of the sub-corpus gives possibility to reveal the pragmatic component of each polylogic item, communicants’ emotional state, possible perlocutionary effect on communicants and on bystanders (not involved readers of the polylogue). The created sub-corpus is a multi-purpose one and can be used in the formation of an integrative “portrait” of participants involved in the social network discourse in this segment of the Internet.
