Lemmatization is the process of converting a word to its base form. Python has nice implementations through the NLTK, TextBlob, Pattern, spaCy and Stanford CoreNLP packages. We will see how to optimally implement and compare the outputs from these packag
To use the older 1.0 models just specify this version in theloadcall:cube.load("en", 1.0)(enfor English, or any other language code). This will download (if not already downloaded) and usethisspecific model version. Same goes for any language/version you want to use. ...
