how to find most common words in text by matlab

how to tag POS on nouns and verbs in MATLAB, Is it related to regular expressions? I know that regular expressions find a pattern in a text, but I want to find the most common words in texts and tag POS on them( I mean the words are nouns or verbs) and then exchange that POS and make an unfamiliar pair of words. how can I find the most common words in texts by MATLAB?is there any solution for that or I should use another software?

Finding the most common words is easy with Text Analytics Toolbox:

>> sonnets = extractFileText("sonnets.txt");
>> sonnets = erasePunctuation(sonnets);
>> tokenizedSonnets = tokenizedDocument(lower(sonnets));
>> bag = bagOfWords(tokenizedSonnets);
>> topkwords(bag, 10)

ans =

    10×2 table

       Word     Count
      ______    _____

      "and"      490 
      "the"      436 
      "to"       409 
      "my"       371 
      "of"       370 
      "i"        344 
      "in"       321 
      "that"     320 
      "thy"      281 
      "thou"     234

You probably want to remove some words (check out removeWords and stopWords). POS tagging is supported in release R2018b and later.
