05 Lemmatization
When tagging text, each word form is assigned a lemma (the base form of the word), facilitating further processing in a unified way. The lemmatization system was developed in the project JOS: Linguistic Annotation of Slovene (Holozan et al. 2008) and follows the MULTEXT-East v4 or JOS morphosyntactic system in determining parts of speech, capitalization and some other features.
Annotation Guidelines
This chapter summarizes the annotation guidelines for the lemmatization of Slovene texts. The guidelines are arranged from the latest, up-to-date version to the oldest version.
