【摘要】 信息行为分析就是对用户的信息搜寻、查找、检索、选择、利用等各项信息行为所做的研究。随着科学技术、社会经济的不断向前发展,用户行为发生的方式与环境也在发生着巨大的变化。因此,用户的信息行为需要重新认识。本文主要研究群体信息行为对个体信息行为认知的影响;认知因素在用户潜在信息需求转化为信息行为的过程中如何起作用;用户在信息源选择这个认知问题解决的过程中,可采取什么选择策略与方法。在对国内外专家学者的研究成果进行回顾的基础上,对研究中涉及到的信息行为分析与认知心理学中的基本概念做了简单的解释;论述了个体行为形成过程的认知特点,个体信息行为改变过程的认知动因,以及群体信息行为对个体信息行为的认知影响;分析了潜在信息需求的产生及其转化的必要性与过程;提出了转化过程的认知信息加工观点,并采用流程图来表示这个转化过程;也提出了用户信息源选择的认知问题解决算子——多项Logit算子,并进行计算模拟。最后展望了信息行为分析中认知研究的前景。
【Abstract】 Information behavior analysis is the research of information seeking, search, retrieval, selection, and utilization on the part of users. As technology and economy march on, almost everything related to information behavior has gone through great changes. As a result, information behavior has to be re-considered.Three things are mainly discussed upon in the paper. One is how to view the relationship between the individual and the group he belongs to from the cognitive perspective. One is how cognition takes effect in the realization of latent information needs. Another is what psychological tactic the user can take when he selects an information source from many.First, an retrospection of famous scholars’ research in recent years are made. Then fundamental concepts in information behavior analysis and cognitive psychology are explained as a preparation for the following chapters. Then, the cognitive effects of group information behavior on individual behavior are elaborated in one whole chapter, characteristics of group information behavior and cognitive characteristcs of individual information behavior included. Next, cognitive research on the realization process of latent infomation needs are elaborated, the cognitive information processing viewpoint putforand and one flowchart for the realization summarized. Besides, one tentative flow chart for the realization is also raised. Afterwards, regarding the problem of user information source selection, one operator called multinomial Logit is tentatively put forward. Finally, work in the paper is summarized and prospects of cognition research in information behavior analysis is briefly described.
