  We present a set of deterministic algorithms for Russian inflection and
automated text synthesis. These algorithms are implemented in a publicly
available web-service www.passare.ru. This service provides functions for
inflection of single words, word matching and synthesis of grammatically
correct Russian text. Selected code and datasets are available at
https://github.com/passare-ru/PassareFunctions/ Performance of the inflectional
functions has been tested against the annotated corpus of Russian language
OpenCorpora, compared with that of other solutions, and used for estimating the
morphological variability and complexity of different parts of speech in
Russian.
