The study’s main goal is to identify keywords and recurrent sequences of words that account for the leaflets’ formulaicity, and - as a secondary goal - to describe their discoursal functions. The keywords were identified using three methods (G2, Hedges’ g and Neozeta) and the overlap between the three metrics was explored. The overlapping keywords were qualitatively analyzed in terms of discoursal functions. As for the distinctive multi-word patterns, we focused on recurrent n-grams with the largest coverage in the corpus: these were identified using the Formulex method (Forsyth, 2015b), which provides complementary data with respect to more conservative n- gram and lexical bundles approaches. The results revealed that the most distinctive keywords were identified using Hedges’ g metric, that the largest overlap occurred between G2 and Neozeta metrics, and that the frequent use and discoursal functions of the identified lexical patterns correspond with situational contexts and communicative purposes of patient information leaflets. It is hoped that this study will provide an opportunity for a methodological reflection and inspire further corpus-driven research on distinctive recurrent lexical patterns (e.g., keywords, n-grams, lexical bundles) or - more generally - on formulaic language in texts originally written in Russian.Данное методологически ориентированное исследование, проведенное с использованием корпусного метода, посвящено анализу наиболее отчетливо выраженных паттернов использования языка в русских инструкциях по применению лекарственных препаратов. Цель исследования двуплановая и заключается, во-первых, в установлении и эксцерпции ключевых слов и повторяющихся словосочетаний, которые вносят вклад в формулярность данного типа текста, и, во-вторых, в последовательном описании их дискурсивных функций. Для эксцерпции ключевых слов использовались три метода: логарифмическая функция правдоподобия (ЛФП), g-Хеджеса и Неодзета. Для дальнейшего качественного анализа были выбраны только ключевые слова, совпадающие во всех трех процедурах. Рекуррентные N-граммы с самым большим лексическим охватом в корпусе извлекались с использованием метода Формулекс (Forsyth 2015b), который предоставляет взаимодополняющие данные относительно более консервативных N-грамм и лексических связок. Результаты показали, что: 1) наиболее ярко выраженные ключевые слова были выявлены c использованием формулы g-Хеджеса; 2) самое большое совпадение ключевых слов было выявлено для формул ЛФП и Неодзета; 3) частотность и дискурсивные функции отобранных слов и словосочетаний обусловлены как ситуативным контекстом, так и коммуникативными функциями инструкций по применению лекарственных препаратов. Исход проведенного анализа позволяет надеяться, что полученные результаты станут толчком для методологических размышлений, а также дальнейших корпусных исследований типичных, часто употребляемых лексических паттернов (например, ключевых слов, N-грамм, лексических связок) и в целом - формулярности русскоязычных текстов.n-gramsformulaic languagephraseologypatient information leafletsRussian languageN-граммышаблонный языкфразеологияинструкции по при- менению лекарственных препаратоврусский язык1.Altenberg, Bernd (1998).
