Best Faces Forward: A Large-scale Study of People Search in the Enterprise - Paper
Community: user experience
Contribution & Benefit: We present Faces, an application built to allow effective large-scale people search in the enterprise, and its usage analysis within IBM along a time period of over 140 days.
Abstract » This paper presents Faces, an application built to enable effective people search in the enterprise. We take advantage of the popularity Faces has gained within a globally distributed enterprise to provide an extensive analysis of how and why people search is used within the organization. Our study is primarily based on an analysis of the Faces query log over a period of more than four months, with over a million queries and tens of thousands of users. The analysis results are presented across four dimensions: queries, users, clicks, and actions, and lay the foundation for further advancement and research on the topic.
The Search Dashboard: How Reflection and Comparison Impact Search Behavior - Paper
Contribution & Benefit: Describes the design of a reflective interface for search. A 5-week study showed that after brief contact, users adopted new behavior. Provides clear next steps for improving the search experience.
Abstract » Most searchers do not know how to use Web search engines as effectively as possible. This is due, in part, to search engines not providing feedback about how search behavior can be improved. Because feedback is an essential part of learning, we created the Search Dashboard, which provides an interface for reflection on personal search behavior. The Dashboard aggregates and presents an individual's search history and provides comparisons with that of archetypal expert profiles. Via a five-week study of 90 Search Dash-board users, we find that users are able to change aspects of their behavior to be more in line with that of the presented expert searchers. We also find that reflection can be beneficial, even without comparison, by changing participants' views about their own search skills, what is possible with search, and what aspects of their behavior may influence search success. Our findings demonstrate a new way for search engines to help users modify their search behavior for positive outcomes.
Building the Trail Best Traveled: Effects of Domain Knowledge on Web Search Trailblazing - Paper
Community: design
Contribution & Benefit: User study on the impact of domain knowledge on Web search trailblazing (creating URL sequences to help searchers). Can assist search engine designers understand the benefit from employing domain-expert trailblazers.
Abstract » Web users can help guide others through complex tasks in unfamiliar domains by creating ordered sequences of queries and Web pages, an activity we call trailblazing. The trails generated from this process can be surfaced by search engines to help users engaged in these tasks. However, if search engines are going to have people generate trails they need to understand whether there is value in using domain experts for trailblazing (or whether novices are sufficient). In this paper, we describe the findings of a user study of trailblazing in the medical domain, comparing domain novices and experts. We observed differences in how people in each of the groups blazed trails and the value of the trails they generated; experts were more efficient and generated better-quality trails. Although there has been significant research on contrasting novice and expert search behaviors, to our knowledge there is no work (at least in the search domain) on establishing whether artifacts created by domain experts (trails in our case) are more valuable than those created by novices. The answer to this question is important for system designers who want to learn whether investing in domain expertise is worthwhile.
A Survey on Web Use: How People Access, Consume, Keep, and Organize Web Content - Long Case Study
Community: designCommunity: user experience
Contribution & Benefit: This survey contributes to the design of cloud content repository by exploring the relationship between content characteristics (contacted by passive delivery vs. active discovery) and behavior (access, consume, keep, organize).
Abstract » We present the results from a preliminary survey concerning the relationship between web content type (contacted by passive delivery or active discovery) and behavior (access, consume, keep, and organize). From the results of the survey, we highlight content specific design suggestion for Tangible Web (TW), our cloud content repository system that enables users to clip, save, format, and organize web content.
