operators for preprocessing:
a. Tokenize: Split the text into individual words or tokens.
b. Transform Cases: Convert the text to lowercase or uppercase to ensure consistency.
c. Remove Stopwords: Remove common words that do not provide much meaningful information.
d. Remove Special Characters: Eliminate special characters, such as punctuation marks or symbols.
e. Remove Numbers: Exclude numeric values from the text.
- Stemming: Apply stemming to reduce words to their root forms. You can use operators like "Stem (Porter)" for this purpose.
