重新查找电子信息是一个常见问题，但与如何首次查找信息问题相比，它受到的研究较少。在这篇论文中，我研究了人们如何处理任务来重新查找他们在网络上看到的信息以及可能影响重新查找的因素。我进行了一项受控的实验室研究，参与者参加了两次会议：一次为一组 18 项任务查找信息，第二次会议大约一周后尝试一组对应的重新查找任务。结果表明，查找和重新查找确实存在差异，但并非适用于所有类型的任务。没有观察到网络搜索引擎的使用从第一次会话到第二次会话有显着变化。然而，对于参与者更熟悉的任务，搜索引擎的使用较少。涉及重新查找在第一次会话中找到的信息子集的任务需要更长的时间才能完成，并且被认为更加困难。参与者经常直接访问网络上的已知资源来开始搜索。这些已知资源集包括许多纸质资源的在线对应物，例如电话簿、词典和报纸。对于许多任务，参与者使用相同的起始策略来重新查找他们用来查找信息的信息，这表明了强大的访问模式。这项工作有助于奠定人们如何重新查找信息以及影响重新查找的因素的知识基础。它还通过确定影响重新查找的维度和因素，为信息重新查找和个人信息管理的研究领域做出贡献。报告的结果对于网站和信息存储库的设计、帮助用户查找和重新查找信息的工具的设计以及研究个人信息管理的研究界都有影响。
Refinding electronic information is a common problem, yet it has received less study than the problem of how to find information for the first time. In this dissertation, I examine how people approach tasks to refind information they have seen on the Web and factors that may affect refinding. I conducted a controlled, laboratory study in which participants participated in two sessions: one to find information for a set of 18 tasks and a second session, about a week later, to attempt a set of counterpart refinding tasks. Results indicate that finding and refinding do have differences, but not for all types of tasks. The use of Web search engines was not observed to change significantly from the first session to the second. However, for tasks that participants were more familiar with, search engines were used less. Tasks that involved refinding a subset of the information that was found in the first session took longer to complete and were perceived as more difficult. Participants often went directly to known resources on the Web to start their searches. These sets of known resources included many on-line counterparts of paper resources such as telephone directories, dictionaries, and newspapers. For many tasks, participants used the same starting strategy to refind the information that they used find it, indicating strong patterns of access. This work contributes to the base of knowledge about how people refind information and the factors that affect refinding. It also contributes to the research field of information refinding and personal information management by identifying dimensions and factors that affect refinding. The results reported have implications for the design of Web sites and information repositories, the design of tools to help users find and refind information, and for the research community studying personal information management.
