我们通过协议分析研究了在 WWW 上寻找信息的认知过程以及受试者的知识和经验对其过程和表现的影响。我们根据科学发现的两个空间模型分析了协议数据。 WWW 上的信息查找过程被认为是搜索两种问题空间的过程：关键字空间和网络空间。实验结果表明：（1）由于知识和经验的影响，专家寻找目标的表现高于新手；（2）在搜索每个空间时，专家对每个空间进行了详细搜索，而新手则没有；（3）从一个空间转移到另一个空间时，专家交替搜索两个空间，而新手则倾向于执着于两个空间之一的搜索。
We investigated cognitive processes of seeking information on the WWW and the effects of subjects' knowledge and experience on their processes and performance through the protocol analysis. We analyzed the protocol data on the basis of the two space model of scientific discovery. The information seeking process on the WWW was considered as a process of searching two kinds of problem spaces: the keyword space and the web space. The experimental results showed that (1) due to the effects of knowledge and experience, the experts' performance of finding a target was higher than that of the novices, (2) when searching each space, the experts searched each space in detail but the novices did not, and (3) when shifting from one space to the other, the experts searched the two spaces alternately, but the novices tended to cling to a search of one of the two spaces.
