Style transformation in natural languages

摘要

To express semantic knowledge of natural languages accurately and unify the processing of languages, the style transformation of natural languages is discussed in an all-round way. The discussion covers purpose, voice, modal, tense, narrow sense of style, number and case. All style transformations may be described accurately by a four-element Descriptive Language of Style Transformation (STDL). The transformation between representation of semantic units without style and with style can be converted through style transformation function. Each style transformation function is a difference function in multiple natural languages. Such difference functions can be used to simplify language processing procedure and improve processing quality.
