Sažetak

The paper presents two conservative Croatian language stemmers, k2 and k3. These stemmers are based on the k1 stemmer, an aggressive Croatian language stemmer presented by Nikola Ljubešić in a 2007 paper. By introducing an expanded set of rules that use derivational morphemes of nouns, verbs, and adjectives to determine the stems of words, we hoped to create a more efficient
stemmer. In order to test whether the k2 and k3 stemmers were more efficient than the k1 stemmer, we calculated their precision, recall, and F1-score using a 9775 token corpus, and compared the results with the precision, recall, and F1-score of the k1 stemmer.
