Lemmatization

MAXDictio permits lemmatization of words in various languages for word frequency and word combination functions.  When this option is activated, words are returned to their respective basic forms, so that words with the same meaning are combined regardless of declination or case. For example, only the word “give” will be counted for the various forms “give”, “gave”, and “given”.

In MAXDictio, lemmatization is performed using lemma lists which are available in the following languages:

  • Bulgarian
  • German
  • English
  • Estonian
  • French
  • Italian
  • Catalan
  • Polish
  • Portuguese
  • Swedish
  • Spanish
  • Czech
  • Ukrainian
  • Hungarian

The lists are in TXT format (UTF-8) and can be edited and expanded as required. It is recommended to create backup copies, because files may be overwritten during a new installation. You can find the lists in the installation folder of MAXQDA:
