To inform the design of next-generation Web search tools, researchers must better understand how users find, manage, and refind online information. Synthesizing results from one of their studies with related work, the authors propose a search engine use model based on prior task frequency and familiarity.
A challenging problem for Internet users today is how to refind information that they have seen before. We believe that finding and refinding are different user activities and require different types of support. The problem of how to find information on the web is studied extensively – new search algorithms, support for natural language queries, and… (More)
Refinding information found on the web is a considerable problem for many users, especially when in mobile situations. In this paper, we explore how a voice-controlled service, accessible by telephone, could help to support mobile users' needs for refinding specific information previously found on the web. We outline challenges in creating such a service… (More)
In this paper, we describe a system and architecture for building and remotely accessing shared context between a user and a computer. The system is designed to allow a user to browse web pages on a personal computer and then remotely make queries about information seen on the web pages using a telephone-based voice user interface.
Mixed-initiative interaction is an important facet of many conversational interfaces, flexible planning architectures, intelligent tutoring systems, and interactive information retrieval systems. Software systems for mixed-initiative interaction must enable us to both operationalize the mixing of initiative (i.e., support the creation of practical dialogs)… (More)
In this paper we describe difficulties involved in studying PIM behaviors and factors that can affect how people approach the refinding process. Factors that have been studied in the context of information seeking behaviors are summarized and their application to PIM and refinding are discussed. Finally, we note the importance of task in evaluating… (More)
Voice Navigation of web spaces has become a reality in the last few years, partly due to the rapid adoption of VoiceXML and the increase in communication quality and computing power of cell-phones. This report discusses some of the approaches on how to convert the web content to a way that could be used from a voice-enabled phone. These approaches have… (More)
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… (More)
