Determine the Part of Speech of Words in Sentence Using Python NLTK

In this tutorial, we will introduce the way to determine the part of speech of words in a sentence. We will use python nltk to implement.

1. Import libraries

from nltk import pos_tag
from nltk import word_tokenize

2. Create a sentence

text_data = "Tom loved outdoor running"

3. Determine the part of speech of words in sentence

text_tagged = pos_tag(word_tokenize(text_data))

# Show parts of speech
print(text_tagged)

You will get the result:

[('Tom', 'NNP'), ('loved', 'VBD'), ('outdoor', 'RP'), ('running', 'VBG')]

Here is a simple list of part of speech in nltk.

Tag	Part Of Speech
NNP	Proper noun, singular
NN	Noun, singular or mass
RB	Adverb
VBD	Verb, past tense
VBG	Verb, gerund or present participle
