Out of curiosity, which do you think is the best one, spaCy 2. To use these libraries for lemmatization, you will typically need first to 4 days ago · Another process performed by spaCy is lemmatization, or the retrieval of the dictionary root word of each word (for example “brighten” for “brightening”). Lemmatization is the process of finding the canonical word given different inflections of the word. These are displayed differently because of the way repr works in Python - it renders strings with single quotes, and spaCy tokens just print the text. Funny thing is, I forgot I installed version 2. English so I don't understand why the lemmatization rules change. The tokenizer is typically created automatically when a Language subclass is initialized and it reads its settings like punctuation and special case rules from the Language.
