信息需求作为一个有一定外部联系和内在结构的有机整体,由于其特殊的质的规定性,既受社会因素的制约,又受个体因素的制约和影响。在不同因素的综合作用中,信息需求结构呈现出一个动态的变化过程。不同的环境条件催生不同的信息需求状态,各种基本状态以及由此决定的不同表现形式,表明了信息需求内部结构的复杂性,这种复杂性呈现出三维立体的结构:信息需求的认知结构、信息需求的效用结构和信息需求的内容结构,三者的划分及相互作用为信息服务提供了一条可以洞察信息市场机制,满足用户需求的清晰思路和可行性理论依据。
As an organic whole with some external connection and internal structure, information demand is restricted by social factors and restricted by individual factors because of its special qualitative regulation. In the combined effect of different factors, the structure of information needs presents a dynamic process of change. Different environmental conditions give rise to different states of information needs, various basic states and the different manifestations thus determined, indicating the complexity of the internal structure of information needs. This complexity presents a three-dimensional structure: the perception of information needs Structure, the structure of the utility of information needs and the content structure of the information needs, the division and interaction of the three provides a clear idea and feasibility of theoretical basis for information services can insight into the mechanism of the information market to meet user needs.
