基于"意义建构"之上的"信息差"理论及模型

本文首先对德尔文“意义建构”理论进行了概括性介绍,然后对德式理论进行了简单分析,在对该理论提出一点质疑的同时,经过从哲学本体论、认识论以及信息论、认知科学的角度做了大量的分析和论证,创新性地提出了在情报学领域中对信息行为研究应建立在“信息差”理论基础上,即在情报学领域内,信息行为集中体现了个体在认知不确定的情况下(信息需求产生的根本原因)对现有的信息系统进行信息差的查寻。本文用了一定的篇幅对信息差理论建立的三个前提作了详尽的论证,进而通过图形及有关函数的表示,对信息差的理论和模型进行了详细的说明。

Study on Theoretic Perspectives and Model of Information Gap-from "The Sense-Making Theory"

This paper gives a brief introduction on Dervin's theory,from which one suspended point is put forward,and at the same time,raises a new theory: Analysis and argumentation are given on Information Gap theory based on ontology,epistemology,information science and cognitive science.The paper asserts that Information Behaviour in the information science incarnates mainly individual information acknowledgment under his / her uncertainty situation.This means that an individual will search information in the information system when he/she has information in need.This paper gives a detailed demonstration about three presupposition on the Information Gap Theory and Model by using functions and figures.
