摘要
本文从认知心理学角度出发,用布鲁克斯方程式阐释了情报个体因吸收新情报而改变其知识结构的过程。这个吸收过程是一个激活式的动态过程,联结强度和知识结构决定被激活区域的范围大小。情报用户的知识结构的激活促使知识结构处于一种动态平衡,前一个平衡促使后一个更高层次的平衡产生,从而生成更复杂的知识结构。这种激活式的结构还可以运用于文献的表达和检索,使之更为准确。
Proceeding from cognitive psychology, this paper uses the Brookes equation to explain the process of the change of the individual＇ s knowledge structure out of his absorbing of new intelligence. The absorption process is an activated dynamic process, in which the scope of the activated knowledge structure is decided by the strength of the intelligence and the structure of knowledge. The activating of individual＇ s knowledge structure prompts a dynamic balance of knowledge structure which will prompt the next higher-level balance, thereby forming a more complicated knowledge structure. This activated knowledge structure can also be used for document presentation and retrieval and make them more precise.
