     "We could see that babies is shortened to `babi`, which is not really an english word, but as long as suffixes of `babi-` are grouped as a single token, it helps in easy processing. But what if we need to be still grammatically correct and trade off with the speed of calculation. In that case we have to use Lemmatization. It is grammatically accurate and it is computationally expensive, since it loads a lemmatizer model."
