Aggregated search is the task of incorporating results from different specialized search services, or verticals, into Web search results. While most prior work focuses on deciding which verticals to present, the task of deciding where in the Web results to embed the vertical results has received less attention. We propose a methodology for evaluating an aggregated set of results. Our method elicits...
In this paper, we explore the question of whether or not perceived time pressure and task difficulty are predictors of users' satisfaction with their search strategies. We conducted a crowd‐sourced user study in which 269 participants completed a total of 600 information‐seeking tasks. Based on self‐reported data gathered from post‐task questionnaires, we found that both perceived time pressure and...
In this demonstration, we present a system called ResultsSpace to support collaborative information seeking by small groups. ResultsSpace is designed to help groups who are collaborating on searches asynchronously, and includes specific user interface features to increase awareness of collaborators' prior actions and progress. We present the main features of ResultsSpace including collaborative ratings...
We describe a collaborative search system called Results Space to support small groups of users in conducting asynchronous collaborative searches. We discuss the design of the system and present results from a laboratory evaluation. We also describe the development of an asynchronous collaborative task scenario (based on a task from the TREC Robust test collection) designed to elicit naturalistic...
In this article we describe the emerging area of text classification research focused on the problem of collaborative learning process analysis both from a broad perspective and more specifically in terms of a publicly available tool set called TagHelper tools. Analyzing the variety of pedagogically valuable facets of learners’ interactions is a time consuming and effortful process. Improving automated...
