This package allows to bring Lefff lemmatization and part-of-speech tagging to a spaCy custom pipeline. This will create new lemma and inflect methods for each spaCy Token. Text Normalization is an important part of preprocessing text for Natural Language Processing. Note that the tokenization function (spacy_tokenizer_lemmatizer) introduced in section 3 returns lemmatized tokens without any stopwords, so those steps are not necessary in our pipeline and we can directly run the preprocessor. They usually are the preferred choice. It consists of taking the root form a word. The XLNet paper goes over this point pretty thoroughly. ; GermaLemma: Looks up lemmas in the TIGER Corpus and uses Pattern as a fallback for some rule-based lemmatizations. For words who's Penn tag indicates they are already in lemma form, the original word is returned directly. Let's call spaCy's lemmatizer L, and the word it's trying to lemmatize w for brevity. Internally spaCy passes token information to a method in Inflections which first lemmatizes the word. $\endgroup$ – Gizio Nov 3 '18 at 17:20.
