Hands-On Tutorial On Polyglot – Python Toolkit For Multilingual NLP Applications

Natural Language Processing is a course of of constructing the human language comprehensible to machines after which performing completely different operations on it to extract helpful data. NLP is part of Artificial Intelligence which makes the interplay between laptop and human language.

There is a big number of python libraries that may assist us in performing NLP duties. All libraries have certain distinctive options and which make them completely different from one another. Generally, NLP libraries have capabilities like Tokenize, Stemming, Lamenting, Spell CHeck, and so on. 

Polyglot is an open-source python library which is used to carry out completely different NLP operations. It is predicated on NumPy which is why it’s quick. It has a big number of devoted instructions which makes it stand out of the crowd. It is just like spacy and can be utilized for languages that don’t help spacy.

In this text, we are going to discover completely different NLP operations and capabilities which may be carried out utilizing polyglot.


Like some other python library, we are going to set up polyglot utilizing pip set up polyglot.

  1. Importing Required Libraries

We will import polyglot and discover its completely different functionalities. All functionalities will probably be imported as and when required.

  1. Performing Operation on Data

Before performing completely different operations on our knowledge, allow us to first initialize some textual content which we are going to use for performing different capabilities on.

init=""'Analytics India Magazine chronicles technological progress within the area of  analytics, synthetic intelligence, knowledge science & massive knowledge by highlighting the improvements, gamers, and challenges shaping the way forward for India by means of promotion and dialogue of concepts and ideas by sensible, ardent, action-oriented people who wish to change the world.'''

  1. Language Detection

Polyglot can establish the language of the textual content handed to it utilizing the language perform. Let us see find out how to use it.

detect = Detector(init)


Language Detector
  1. Tokenize

In tokenize, we are able to print the wordlist which is the phrases which can be there within the textual content used in addition to the sentences that are there within the textual content. 

from polyglot.textual content import Text

textual content = Text(init)

textual content.phrases


textual content.sentences

Sentences Detection
  1. POS Tagging

Parts of speech tagging is used to identify the syntactic performance of phrase prevalence.

from polyglot.mapping import Embedding

textual content.pos_tags

POS Tagging
  1. Named Entity Extraction

It extracts phrases from the plain textual content which can be entities like location, particular person, and organizations.

textual content.entities

Named Entity Extration

Let us do this with some extra texts. 

init1 = '''Hello my identify is Himanshu Sharma and I'm from India'''

textual content = Text(init1)

textual content.entities

  1. Morphological evaluation

It defines the regularities behind phrase formation in human language. Let us see find out how to use it.

from polyglot.textual content import Word

phrases = ["programming", "parallel", "inevitable", "beautiful"]

for w in phrases:

     w = Word(w, language="en")

     print(w, w.morphemes)

Morphological Analysis
  1. Sentiment Analysis

textual content = Text("The new economic policies are quite good.")

for w in textual content.phrases:

    print(w, w.polarity)

Sentiment Extraction

These are a number of the NLP operations which we are able to carry out utilizing polyglot.


In this text we noticed how polyglot can be utilized to detect the language we’re utilizing in a selected textual content, adopted by the tokenization in phrases and sentences. We noticed how we are able to use named entity recognition and sentiment evaluation. Polyglot is simple to make use of and can be utilized for a wide range of od NLP operations.
