Auto-Correct in NLP

you have to follow these steps:

  • Identify a misspelled word

  • Find strings n edit distance away: (these could be random strings)

  • Filter candidates: (keep only the real words from the previous steps)

  • Calculate word probabilities: (choose the word that is most likely to occur in that context)

step 1

step 2- identify strings which are n edits away.

step 3- keep only the words that are present in dictionary.

Step 4 - calculate the filtered words probabilities from the entire corpus.

word with the maximum probability is the best replacement.
