Lemmatization & Dialog Systems 2018


Notes:

Lemmatisation in linguistics is the process of grouping together the inflected forms of a word so they can be analysed as a single item, identified by the word’s lemma, or dictionary form.

  • Lemmatisation
  • Lemmatize
  • Lemmatized
  • Lemmatizer
  • Lemmatizing
