摘要
通过对信息检索认知理论的研究,构建信息检索认知模型。依据信息检索认知模型及认知负荷理论,构建信息检索认知过程中认知负荷结构模型,并提出认知负荷评价的基本框架。通过实证研究,对数字图书馆信息检索认知过程中的认知负荷进行评价并指出其动态变化。
This paper defines the user cognitive model of information retrieval through the analysis of cognitive theory. Based on the cognitive model of information retrieval and cognitive load theory, it constructs the structural model of the cognitive load in the cognitive processes of information retrieval and the cognitive load framework. It evaluates information retrieval of digital library in the cognitive processes of cognitive load by empirical research, and pointes out that the cognitive load dynamically changes in the cognitive process of information retrieval.
