Spelling checker in Python

For any type of text processing or analysis, checking the spelling of the word is one of the basic requirements. This article discusses various ways that you can check the spellings of the words and also can correct the spelling of the respective word.
 

Using textblob library

First, you need to install the library textblob using pip in command prompt. 

pip install textblob 

You can also install this library in Jupyter Notebook as: 
 

import sys !{sys.executable} - m pip install textblob 

  
Program for Spelling checker - 
 

from textblob import TextBlob a = "cmputr" # incorrect spelling print("original text: "+str(a)) b = TextBlob(a) # prints the corrected spelling print("corrected text: "+str(b.correct())) 

Output: 
 

original text: cmputr corrected text: computer

Using pyspellchecker library

You can install this library as below:
Using pip: 

pip install pyspellchecker

In Jupyter Notebook: 
 

import sys !{sys.executable} - m pip install pyspellchecker 

  
Spelling Checker program using pyspellchecker - 
 

from spellchecker import SpellChecker spell = SpellChecker() # find those words that may be misspelled misspelled = spell.unknown(["cmputr", "watr", "study", "wrte"]) for word in misspelled: # Get the one `most likely` answer print(spell.correction(word)) # Get a list of `likely` options print(spell.candidates(word)) 

Output: 
 

computer {'caput', 'caputs', 'compute', 'computor', 'impute', 'computer'} water {'water', 'watt', 'warr', 'wart', 'war', 'wath', 'wat'} write {'wroe', 'arte', 'wre', 'rte', 'wrote', 'write'}

Using JamSpell

To achieve the best quality while making spelling corrections dictionary-based methods are not enough. You need to consider the word surroundings. JamSpell is a python spell checking library based on a language model. It makes different corrections for a different context.

1) Install swig3

apt-get install swig3.0 # for linux brew install swig@3 # for mac

2) Install jamspell

pip install jamspell

3) Download a language model for your language

# Create a corrector corrector = jamspell.TSpellCorrector() # Load Language model -  # argument is a downloaded model file path corrector.LoadLangModel('Downloads/en_model.bin') # To fix text automatically run FixFragment: print(corrector.FixFragment('I am the begt spell cherken!')) # To get a list of possible candidates  # pass a splitted sentence, and a word position print(corrector.GetCandidates(['i', 'am', 'the', 'begt', 'spell', 'cherken'], 3)) print(corrector.GetCandidates(['i', 'am', 'the', 'begt', 'spell', 'cherken'], 5)) 

Output:

u'I am the best spell checker!' (u'best', u'beat', u'belt', u'bet', u'bent') (u'checker', u'chicken', u'checked', u'wherein', u'coherent', ...)
