Text normalization

Text normalization is like cleaning up your toys after playing with them. Just like how you have to put your toys back in their proper places so that you can find them easily later on, similarly text normalization puts words in their proper places in a sentence so that computers can understand them better.

For example, sometimes people write "u" instead of "you" or "2" instead of "to". But a computer doesn't understand these shortcuts and gets confused. So text normalization changes these shortcuts into their full forms so that the computer can understand them.

It also helps to correct the spelling mistakes by changing incorrect spellings of words to their correct spellings. This is like when mom tells you the correct way to spell a word when you write it wrong.

So, text normalization is just like cleaning up messy words so that computers can easily understand them and communicate with us.
