Exercise

Stems and lemmas from GoT

In this exercise, you are given a couple of sentences from George R.R. Martin's Game of Thrones. Your task is to create stems and lemmas from the given GoT string.

Remember that stems reduce a word to its root whereas lemmas produce an actual word. However, speed can differ significantly between the methods with stemming being much faster. In Steps 2 and 3, pay attention to the total time it takes to perform each operation. We're making use of the time.time() method to measure the time it takes to perform stemming and lemmatization.
