  • Visual Information Seeking
    Journal of the Association for Information Science and Technology, 2014
    Co-Authors: Dan Albertson
    Abstract:

    The present study reports on the Information Seeking Processes in a visual context, referred to throughout as visual Information Seeking. This study synthesizes research throughout different, yet complementary, areas, each capable of contributing findings and understanding to visual Information Seeking. Methods previously applied for examining the visual Information Seeking Process are reviewed, including interactive experiments, surveys, and various qualitative approaches. The methods and resulting findings are presented and structured according to generalized phases of existing Information Seeking models, which include the needs, actions, and assessments of users. A review of visual Information needs focuses on need and thus query formulation; user actions, as reviewed, centers on search and browse behaviors and the observed trends, concluded by a survey of users' assessments of visual Information as part of the interactive Process. This separate examination, specific to a visual context, is significant; visual Information can influence outcomes in an interactive Process and presents variations in the types of needs, tasks, considerations, and decisions of users, as compared to Information Seeking in other contexts.

  • INSYDER: a content-based visual-Information-Seeking system for the Web
    International Journal on Digital Libraries, 2005
    Co-Authors: Harald Reiterer, Gabriela Tullius, Thomas M. Mann
    Abstract:

    This paper presents INSYDER, a content-based visual-Information-Seeking system for the Web. The Web can be seen as one huge digital library offering a variety of very useful Information for business analysts. INSYDER addresses these possibilities and offers powerful retrieval and visualisation functionalities. The main focus during the development was on the usability of the system. Therefore, a variety of well-established visualisation components were employed to support the user during the Information-Seeking Process (e.g. visual query, result table, bar graph, segment view with tile bars, and scatterplot). Also, the retrieval aspects were developed with the goal of increasing the usability of the system (e.g. natural language search, content-based classification, relevance feedback). Extensive evaluations of the retrieval performance and the usability of the visualisation were conducted. The results of these evaluations offered many helpful insights into developing a new visual-Information-Seeking system called VisMeB.

  • DEXA Workshop - Evaluation of different visualizations of Web search results
    Proceedings 11th International Workshop on Database and Expert Systems Applications, 1
    Co-Authors: Thomas M. Mann, Harald Reiterer
    Abstract:

    The paper discusses the evaluation of a visual Information Seeking system for the Web called INSYDER. The aim of INSYDER is to find business Information on the Web. The evaluation compares different visualizations including HTML-List, ResultTable, ScatterPlot, BarGraph and SegmentViews. These visualizations support the interpretation of the search result phase of the Information Seeking Process. First results of the evaluation with forty users are presented and an outlook on future work is given.

  • using eye tracking to investigate patent examiners Information Seeking Process
    Information Retrieval Facility Conference, 2014
    Co-Authors: Fernando Loizides, Barrou Diallo
    Abstract:

    In this paper we present a methodology which was tested for using eye-tracking to record patent examiners’ visual attention during patent triage. The findings present ways that the eye-tracker can complement current metrics for evaluating Information retrieval tools, as well as the ability to investigate further behaviors and actions which cannot be done by currently employed methods.

  • ECDL - An empirical study of user navigation during document triage
    Research and Advanced Technology for Digital Libraries, 2009
    Co-Authors: Fernando Loizides, George Buchanan
    Abstract:

    Document triage is the moment in the Information Seeking Process when the user first decides the relevance of a document to their Information need[17]. This paper reports a study of user behaviour during document triage. The study reveals two main findings: first, that there is a small set of common navigational patterns; second, that certain document features strongly influence users' navigation.

  • ECDL - Investigating document triage on paper and electronic media
    Research and Advanced Technology for Digital Libraries, 2007
    Co-Authors: George Buchanan, Fernando Loizides
    Abstract:

    Document triage is the critical point in the Information Seeking Process when the user first decides the relevance of a document to their Information need. This complex Process is not yet well understood, and subsequently we have undertaken a comparison of this task in both electronic and paper media. The results reveal that in each medium human judgement is influenced by different factors, and confirm some unproven hypotheses. How users claim they perform triage, and what they actually do, are often not the same.

  • ECDL - MedioVis – a user-centred library metadata browser
    Research and Advanced Technology for Digital Libraries, 2005
    Co-Authors: Christian Grün, Jens Gerken, Hans-christian Jetter, Werner A. König, Harald Reiterer
    Abstract:

    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.
