Users of search engines often abandon their searches. Despite the high frequency of Web search abandonment and its importance to Web search engines, little is known about <i>why</i> searchers abandon beyond that it can be for good or bad reasons. In this paper, we ex-tend previous work by studying search abandonment using both a retrospective survey and an(More)
Exploratory search activities tend to span multiple sessions and involve finding, analyzing and evaluating information found through many queries. Typical search systems, on the other hand, are designed to support single query, precision-oriented search tasks. We describe a search interface and system design of a multi-session exploratory search system,(More)
Interactive Query Expansion (IQE) presents suggested terms to the user during their search to enable better Information Retrieval (IR). However, IQE terms are poorly used, and tend to lack information meaningful to the user. The lack of cognitive and functional support during query refinement is a well documented problem, and despite the work carried out,(More)
People spend an enormous amount of time searching for complex information online; for example, consumers researching new purchases or patients learning about their conditions. As they search, people build up rich mental schemas about their target domains; which, if effectively shared, could accelerate learning for others with similar interests. In this(More)
People spend an enormous amount of time searching for and saving information online. Existing tools capture only a small portion of the cognitive processing a user engages in while making sense of a new domain. In this paper we introduce a novel interface for capturing online information in a structured but lightweight way. We use this interface as a(More)
We describe an on-going design process in building Querium, a search system for multi-session exploratory search tasks. Querium extends a conventional search interface with a sophisticated search history interface that helps people make sense of their search activity over time. Information seeking is a cognitively demanding process that can benefit from(More)
