• Eradicating particular characters: Take away punctuation, symbols, or non-alphanumeric characters that don’t contribute to the which means of the textual content.
• Eradicating numbers: Take away numerical digits if they aren’t related to the evaluation.
• Lowercasing: Convert all textual content to lowercase to make sure consistency in textual content matching and evaluation.
• Eradicating cease phrases: Take away frequent phrases that don’t carry a lot info, corresponding to “a”, “the”, “is”, and so forth.

Tokenization

• Splitting textual content into phrases or tokens: Cut up the textual content into particular person phrases or tokens to organize for additional evaluation. Researchers can obtain this by using whitespace or extra superior tokenization strategies, corresponding to using libraries like NLTK or spaCy.

Normalization

• Lemmatization: Cut back phrases to their base or dictionary type (lemmas). For instance, changing “working” and “ran” to “run”.
• Stemming: Cut back phrases to their base type by eradicating prefixes or suffixes. For instance, changing “working” and “ran” to “run”.
• Eradicating diacritics: Take away accents or different diacritical marks from characters.
