For example, an exclamation point indicates emotional intensity, while a question may indicate uncertainty. Sentiment Dictionary: Contains a list of words that have been classified as positive or negative. Emotions can be quickly identified by comparing words in text with words in the dictionary. Training the Classifier Once the text features have been extracted, the classifier can be trained to predict the sentiment of the text. Commonly used classifiers include: Naive Bayes: A simple classifier based on the assumption of independence of features. Support Vector Machines:
