Data Preprocessing is about clearing the stopwords, removing special characters, lemmatization, stemming etc. The input data is the one that we got from the previous experiment, the reader gets the stopwords from a Windows Blob storage, text.preprocessing is a sort of library that has the all the inbuilt generalized functions and procedures in R.
