There is an old English folk saying that goes, "If you can't stand the heat, get out of the kitchen." I have a different approach: Do something about the heat. The folk saying would have us accept the poor designs of the world. Why? After all, if people were responsible for the "heat" in the first place, then people should be able to do something about it. Is the kitchen too hot? Redesign it.

Ahn, Jae-wook and Brusilovsky, Peter (2011): Guiding educational resources for iSchool students with topic-based adaptive visualization. In: Proceedings of the 2011 iConference 2011. pp. 632-633.

Information visualizations can be applied to the educational domain in order to help the students access appropriate educational resources. We present a novel adaptive visualization method that supports navigations through class materials according to the lecture topics. The map-based adaptive annotations and the relevance-based visualizations are supported in the framework. We are going to use the system in a real iSchool class and will conduct a user study in order to validate the effectiveness of the idea.

Ahn, Jae-wook and Brusilovsky, Peter (2010): What you see is what you search: adaptive visual search framework for the web. In: Proceedings of the 2010 International Conference on the World Wide Web 2010. pp. 1049-1050.

Information retrieval is one of the most popular information access methods for overcoming the information overload problem of the Web. However, its interaction model is still utilizing the old text-based ranked lists and static interaction algorithm. In this paper, we introduce our adaptive visualization approach for searching the Web, which we call Adaptive VIBE. It is an extended version of a reference point-based spatial visualization algorithm, and is designed to serve as a user interaction module for a personalized search system. Personalized search can incorporate dynamic user interests and different contexts, improving search results. When it is combined with adaptive visualization, it can encourage users to become involved in the search process more actively by exploring the information space and learning new facts for effective searching. In this paper, we introduce the rationale and functions of our adaptive visualization approach and discuss the approaches' potential to create a better search environment for the Web.

Ahn, Jae-wook and Brusilovsky, Peter (2010): Can Concept-Based User Modeling Improve Adaptive Visualization?. In: Proceedings of the 2010 Conference on User Modeling, Adaptation and Personalization 2010. pp. 4-15.

Adaptive visualization can present user-adaptive information in such a way as to help users to analyze complicated information spaces easily and intuitively. We presented an approach called Adaptive VIBE, which extended the traditional reference point-based visualization algorithm, so that it could adaptively visualize documents of interest. The adaptive visualization was implemented by separating the effects of user models and queries within the document space and we were able to show the potential of the proposed idea. However, adaptive visualization still remained in the simple bag-of-words realm. The keywords used to construct the user models were not effective enough to express the concepts that need to be included in the user models. In this study, we tried to improve the old-fashioned keyword-only user models by adopting more concept-rich named-entities. The evaluation results show the strengths and shortcomings of using named-entities as conceptual elements for visual user models and the potential to improve the effectiveness of personalized information access systems.

Personalized Web search has emerged as one of the hottest topics for both the Web industry and academic researchers. However, the majority of studies on personalized search focused on a rather simple type of search, which leaves an important research topic -- the personalization in exploratory searches -- as an under-studied area. In this paper, we present a study of personalization in task-based information exploration using a system called TaskSieve. TaskSieve is a Web search system that utilizes a relevance feedback based profile, called a "task model", for personalization. Its innovations include flexible and user controlled integration of queries and task models, task-infused text snippet generation, and on-screen visualization of task models. Through an empirical study using human subjects conducting task-based exploration searches, we demonstrate that TaskSieve pushes significantly more relevant documents to the top of search result lists as compared to a traditional search system. TaskSieve helps users select significantly more accurate information for their tasks, allows the users to do so with higher productivity, and is viewed more favorably by subjects under several usability related characteristics.

Ahn, Jae-wook, Brusilovsky, Peter, Grady, Jonathan, He, Daqing and Syn, Sue Yeon (2007): Open user profiles for adaptive news systems: help or harm?. In: Proceedings of the 2007 International Conference on the World Wide Web 2007. pp. 11-20.

Over the last five years, a range of projects have focused on progressively more elaborated techniques for adaptive news delivery. However, the adaptation process in these systems has become more complicated and thus less transparent to the users. In this paper, we concentrate on the application of open user models in adding transparency and controllability to adaptive news systems. We present a personalized news system, YourNews, which allows users to view and edit their interest profiles, and report a user study on the system. Our results confirm that users prefer transparency and control in their systems, and generate more trust to such systems. However, similar to previous studies, our study demonstrate that this ability to edit user profiles may also harm the system's performance and has to be used with caution.

Brusilovsky, Peter, Farzan, Rosta and Ahn, Jae-wook (2005): Comprehensive personalized information access in an educational digital library. In: JCDL05: Proceedings of the 5th ACM/IEEE-CS Joint Conference on Digital Libraries 2005. pp. 9-18.

This paper explores two ways to help students locate most relevant resources in educational digital libraries. One method gives a more comprehensive access to educational resources, through multiple pathways of information access, including browsing and information visualization. The second method is to access personalized information through social navigation support. This paper presents the details of the Knowledge Sea II system for comprehensive personalized access to educational resources and also presents the results of a classroom study. The study delivered a convincing argument for the importance of providing multiple information presentations modes, showing that only about 10% of all resource accesses were made through the traditional search interface. We have also collected some solid evidence in favor of the social navigation support.
