#1

How many trigrams phrases can be generated from the following sentence, after performing following text cleaning steps:

  • Removing stopwords
  • Replacing punctuations by single space

“#Coding-Blocks is a great source to learn @machine_learning.”

My understanding: after stopword removal it would be:
Coding-Blocks great source learn machine_learning

So there would be three Trigrams:

  1. Coding-Blocks great source
  2. great source learn
  3. source learn machine_learning

Please let me know what I am missing here.

Hey @tisandas2011, you also need to remove ‘-’, and ‘_’ as well.
The resultant string will be “Coding Blocks great source learn machine learning” and answer will be 5.

Hope this resolved your doubt.
Plz mark the doubt as resolved as well.
