LatvianStemmer Light stemmer for Latvian.

This is a light version of the algorithm in Karlis Kreslin's PhD thesis A stemming algorithm for Latvian with the following modifications:

  • Only explicitly stems noun and adjective morphology
  • Stricter length/vowel checks for the resulting stems (verb etc suffix stripping is removed)
  • Removes only the primary inflectional suffixes: case and number for nouns ; case, number, gender, and definitiveness for adjectives.
  • Palatalization is only handled when a declension II,V,VI noun suffix is removed.
