Evaluating exploratory visualization systems: A user study on how clustering-based visualization systems support information seeking from large document collections

Yujie Liu, Scott Barlowe, Yaqin Feng, Jing Yang, Min Jiang
2012 Information Visualization  
Through this study, we analyze how and why clustering-based EVSs benefit (or not) users in a variety of information seeking tasks.  ...  Exploratory visualization systems (EVSs) maximize users' information gain through learning and have been widely used in scientific discovery and decision making contexts.  ...  Conceptual description and system practice [7] , which have been proved effective in mental model building, can be employed.  ...

An analysis of two approaches in information retrieval: From frameworks to study designs

Kalervo Järvelin
2007 Journal of the American Society for Information Science and Technology  
There is a well-known gap between Systems-oriented IR and User-oriented IR, which Cognitive IR seeks to bridge.  ...  This becomes apparent in the use of independent, controlled and dependent variables in the study designs of each approach.  ...  Regarding information retrieval, the search process is not represented nor the other information access processes of which retrieval forms a part and contributes to in practice.  ...

A user-centered approach to evaluating human interaction with Web search engines: an exploratory study

Amanda Spink
2002 Information Processing & Management  
The goal of the study reported in this paper was to develop a user-centered approach to the evaluation including: (1) effectiveness: based on the impact of users' interactions on their information problem  ...  Some users experienced major changes/shifts in various userbased variables, such as information problem or information seeking stage with a search of low precision and vice versa.  ...  This evaluation approach is based on a theoretical framework and model that conceptualizes Web searching within a user's information seeking and retrieving context outlined in the next section of this  ...

Report on ACM SIGIR 2006 workshop on evaluating exploratory search systems

Ryen W. White, Gheorghe Muresan, Gary Marchionini
2006 SIGIR Forum  
Exploratory search systems (ESS) are designed to help users move beyond simply finding information toward using that information to support learning, analysis, and decision-making.  ...  The evaluation of the interactive systems designed specifically to help exploratory searchers is a challenging area, worthy of further discussion in the research community.  ...  Perhaps the most complete model integrated the information seeker, search task, information base, search system, and effects.  ...
