This module is mainly aimed at understanding the underlying sentiment of a statement. First, NLP is used in basic preprocessing of the data. Once the preprocessin is completed, the sentence is classified into one of the following types:

1. Statement/ Declarative Sentence
2. Question/ Interrogative Sentence
3. Exclamation/ Exclamatory Sentence
4. Command/ Imperative Sentence

Underlying Concepts: Any sentence comprises of two major parts: Subject and Predicate. (Exception being in the Imperative Sentences where the subject is left out or 'YOU' is understood to be the subject). Phrase is a group of words that define a portion of a sentence typically forming a component of a clause. Clause is part of a sentence which has both and subject in it.
