Abstract—In common Web-based search interfaces, it can be difficult to formulate queries that simultaneously combine temporal, spatial, and topical data filters. We investigate how coordinated visualizations can enhance search and exploration of information on the World Wide Web by easing the formulation of these types of queries. Drawing from visual information seeking and exploratory search, we introduce VisGets – interactive query visualizations of Web-based information that operate with online information within a Web browser. VisGets provide the information seeker with visual overviews of Web resources and offer a way to visually filter the data. Our goal is to facilitate the construction of dynamic search queries that combine filters from more than one data dimension. We present a prototype information exploration system featuring three linked VisGets (temporal, spatial, and topical), and used it to visually explore news items from online RSS feeds. Index Terms—Information visualization, World Wide Web, information retrieval, exploratory search, visual information seeking. 1

MedioVis is a visual information seeking system which was designed especially for library data. The objective target was to create a system which simplifies and optimizes the user's information seeking process and thus further motivates the user to browse in the library stock. To enhance the motivation special attention was given to consider joy of use aspects during the design of the user interface. The primary user interface design is based on multiple coordinated views to offer a great variety of exploration possibilities in a direct-manipulative manner. To accomplish a self-explanatory usability of the system for non-expert users, the development was accompanied by continuous user tests with casual and regular library users. At the end of the development process a comprehensive summative evaluation was conducted, comparing efficiency and joy of use of the existing web-based catalogue system KOALA of the library of the University of Konstanz with the MedioVis system. The results of this comparative evaluation show a significant improvement of the efficiency of the information seeking process with the help of MedioVis. The users also rated MedioVis significantly better in all dimensions of its hedonic quality and appeal compared with KOALA.

We propose a new way of navigating the Web using interactive information visualizations, and present encouraging results from a large-scale Web study of a visual exploration system. While the Web has become an immense, diverse information space, it has also evolved into a powerful software platform. We believe that the established interaction techniques of searching and browsing do not sufficiently utilize these advances, since information seekers have to transform their information needs into specific, text-based search queries resulting in mostly text-based lists of resources. In contrast, we foresee a new type of information seeking that is high-level and more engaging, by providing the information seeker with interactive visualizations that give graphical overviews and enable query formulation. Building on recent work on faceted navigation, information visualization, and exploratory search, we conceptualize this type of information navigation as visual exploration and evaluate a prototype Web-based system that implements it. We discuss the results of a large-scale, mixed-method Web study that provides a better understanding of the potential benefits of visual exploration on the Web, and its particular performance challenges.

Abstract The paper presents the structure and function of an ethical micro world simulation and of a support system in ethical problem-solving and decision-making. The ethical micro world simulation models realistic scenarios with interacting independent stakeholders. Users of the simulation are triggered to make autonomous decisions in dilemmas arising in the interaction between stakeholders. The goals are to investigate the possible approaches to implement the psychological approach to ethical problem-solving and decision-making, and to stimulate higher ethical competence. The ethical support system is based on the theory of autonomy. By using it thinking is guided away from heteronomy and toward autonomy. Its basic features are: 1) not allow the user to use the system as a moral authority, 2) not present a ready made set of moral principles and values, 3) help the user to be unconstrained by moral fixations and authorities, 4) help the user to organize and analyze the facts, 5) help the user to weight the relevant values and principles against each other, 6) help the user to solve the moral problem at hand systematically, 7) force the user to motivate his/her decisions in regard to the relevant interests and values.

In this paper we will present a new approach combining different visualizations into a so called SuperTable with a Scatterplot. The goal was to improve user experience during the information seeking process. Originally INSYDER was a system to supply small and medium size enterprises with business information from the Internet by using a local meta search engine. The new prototype will be much more flexible concerning the operational area as well as the used visualizations. Instead of offering multiple visualizations to choose from INSYDER combines them into one, reducing the confusion of different visualizations. 1

This dissertation investigates the use of categorized overviews of web search results, based on meaningful and stable categories, to support exploratory search. When searching in digital libraries and on the Web, users are challenged by the lack of effective overviews. Adding categorized overviews to search results can provide substantial benefits when searchers need to explore, understand, and assess their results. When information needs are evolving or imprecise, categorized overviews can stimulate relevant ideas, provoke illuminating questions, and guide searchers to useful information they might not otherwise find. When searchers need to gather information from multiple perspectives or sources, categorized overviews can make those aspects visible for interactive filtering and exploration. However, they add visual complexity to the interface and increase the number of tactical decisions to be made while examining search results. Two formative studies (N=18 and N=12) investigated how searchers use categorized overviews in the domain of U.S. government web search. A third study (N=24) evaluated categorized overviews of general web search results based on thematic,
