NLP-Oriented Study on the Imperative Sentence with Interrogative Mood

Abstract

Imperative sentence with interrogative mood (ISIM) is a transitional category between imperative sentence and interrogative sentence. It has both the form of interrogative sentence and the function to transfer information of imperative sentence. So, the classification and meaning of ISIM become argumentative in study and application in Natural Language Processing. In this paper, the author claims three points in this paper: first, there are two parts of ISIM: imperative center which transfers imperative information and interrogative structure which makes the whole sentence more euphemistic, second, there are four types of ISIM in form: attached imperative sentence, imperative sentence of positive and negative, imperative sentence of right and wrong, rhetorical imperative sentence, third, the semantic and types of interrogative structure will affect the semantic of whole sentence.
