Since we all know that the language of computers is Numerical, the very first step that comes to our mind is to convert our language to numbers.
This conversion takes a few steps to happen. The first step to it is Text Normalization. Since human languages are complex, we need to first of all simplify them in order to make sure that the understanding becomes possible. Text Normalization helps in cleaning up the textual data in such a way that it comes down to a level where its complexity is lower than the actual data.
