In this paper, we look at a paradigm leveling process currently taking place in Russian that affects historical consonant alternations (morphophonemic alternations that arose as a result of historical sound changes in Slavic and Russian specifically). In Standard Russian, these alternations are present in some verb forms (ljubit' 'to love'-ljublju 'I love'), in comparatives (suxoj 'dry'-suše 'drier, more dryly'), in deverbal nouns, and in some other grammatical categories. However, many non-standard forms in Russian lack alternations or have 'incorrect' alternations unattested in the standard language. Unfortunately, Russian corpora contain almost no such non-standard forms, and the best source of such data is the Internet. However, estimating relative frequencies of different forms found on the Internet is a challenge because the counts provided by search engines are extremely unreliable. We developed various strategies and a program to circumvent this problem and applied the technique to our study of alternations primarily in comparatives and to some extent also in verb forms.
