ESTMORF is a computer program for analysing unrestricted Estonian text. ESTMORF is implemented in a most straightforward way: it compares word forms of the running text with combinations of lexemes from its lexicon.
ESTMORF determines, for every input word form, the structure of the word (e.g. stem, derivational suffix, inflectional affix), the word class and inflectional categories (e.g. number and case).
