In linguistic morphology, _____________ is the process of reducing inflection in words to their root forms such as mapping a group of words to the same stem even if the stem itself is not a valid word in the language.

• Stemming

• Rooting

• Text-Proofing

• Lemmatization

____________ is a Python library to make programs that work with natural language.

• Keras

• NLTK

• Pandas

• Seaborn

Stop Words are words which do not contain important significance to be used in Search Queries. Usually, these words are filtered out from search queries because they return a vast amount of unnecessary information. Mostly they are words that are commonly used in English language such as 'as, the, be, are' etc.

• True

• False

Lemmatization, unlike Stemming, reduces the inflected words properly ensuring that the root word is the dictionary form. For example, runs, running, ran are all forms of the word run.
