Text preprocessing involves cleaning and tokenizing the text, removing stopwords, and stemming or lemmatizing words. Feature extraction involves converting the text into numerical features that can be used by machine learning algorithms. Sentiment classification involves training a model to classify text into positive, negative, or neutral categories. Sentiment scoring involves assigning a sentiment score to the text based on the classification results.
