_r1_scandinavian(self, word, vowels)

source code 

Return the region R1 that is used by the Scandinavian stemmers.

R1 is the region after the first non-vowel following a vowel, or is the null region at the end of the word if there is no such non-vowel. But then R1 is adjusted so that the region before it contains at least three letters.

Parameters:
  • word (str, unicode) - The word whose region R1 is determined.
  • vowels (unicode) - The vowels of the respective language that are used to determine the region R1.
Returns: unicode
r1, the region R1 for the respective word.

Note: This helper method is invoked by the respective stem method of the subclasses DanishStemmer, NorwegianStemmer, and SwedishStemmer. It is not to be invoked directly!
