摘要
信息片段是个意义单位 ,是话语中一定数量的信息 ,具有可处理性、内部的整体性和外部的离散性。对信息片段的界定不能从句子表层的形式出发 ,而必须从深层的意义出发 ,是一个以逻辑命题为基础、听者可以一次处理、包含已知信息和未知信息两个结构成分的语段。对信息片段的切分有内部切分和外部切分两种。在内外切分中 ,提出了必须遵守的两个原则 :以外就内和以小就大 ,旨在对切分的深度进行限制。内外切分的目的在于把握信息传递的基本格局和流程。
As an information unit, a piece of information is a quantum or unit of information. It's a meaningful segment of utterance by the speaker that can be independently and inseperately processed by the hearer. As a result, it is defined, from the perspective of the meaning or information rather than from the perspective of the form of the segment, as a proposition based segment with given information and new information as its two constituents. A piece of information can be divided internally and externally. The divisions are governed by two principles: the internal prior to the external division and a bigger prior to a smaller constituent. The purpose of the divisions is to show the order or structure of the information flow.
