The authors address the needs of academicians in different fields of knowledge investigating collective memory and its discursive practices, its various manifestations in language subsystems, and the principles and mechanisms of social communication. Based on the significant potential of cognitive linguistics in this area due to the links between memory and language, the authors present this study аs to how social and cultural institutions regulate collective memory and apply different strategies, tactics, and linguistic means to create positive, negative, and neutralized images of the past in German mass media discourse. This study reveals the most relevant textproducer policies used to manipulate text-recipients and focuses on the most relevant argumentative and compositional tactics used in German mass media to re-actualize and form images of the collective past. The authors view re-actualization of collective memory in mass media in terms of social communication and media priming theories wherein collective memory is a phenomenon socially constructed in discursive practices, which perform selective, interpretive, and reversible functions. Managing the delivery of transformed images of the past to the addressee is aimed at cognitive and axiological changes in the communicative space of the addressee and forming the value judgment of the past. It is considered be possible due to the agent-object relationship of the addresser and addressee. The tactics applied by the addresser contribute not only to distributing and emphasizing some pieces of information but reducing criticism of the mass recipient perception.

This article presents three mathematical models to differentiate academic texts from three subject discourses written in Russian (i.e., Philological, Mathematical, and Natural Sciences) which further enable design and automated profiling of corresponding typologies. Our models include 5 indices, one at surface level (i.e., sentence length) and 4 syntax features (i.e., mean verbs per sentence, mean adjectives per sentence, local noun overlap, and global argument overlap). We identified and validated the five statistically significant features out of 45 linguistic features extracted from our research corpus consisting of 91.185 tokens. The shortest sentence length is found in Russian language textbooks while the longest sentences are identified in Natural Science texts. The mean number of verbs, nouns, and adjectives per sentence is higher in Natural Science textbooks, whereas Mathematics discourse is characterized by the shortest word length, highest local noun overlap, and highest global argument overlap. We assign the metric differences between the three discourses to their functions: Natural Science texts are characterized by descriptions and narrative passages in contrast to Philology that is associated with opinions. Mathematical discourse operates with precise definitions, explanations and justifications thus exercising numerous overlaps. The discriminant analysis built on top of the features supports the development of text profilers targeting parametric analyses. The automation of these features and the provided formulas for classification enable the design and development of text profilers required for textbook writing and editing. Our findings are useful for professional linguists, technologists, and academic writers to select and modify texts for their target audience.
