  • Influence of training and stage of search on gaze behavior in a Library Catalog faceted search interface
    Journal of the Association for Information Science and Technology, 2011
    Co-Authors: Bill Kules, Robert Capra
    Abstract:

    This study examined how searchers interact with a web-based, faceted Library Catalog when conducting exploratory searches. It appliedmultiple methods, including eye tracking and stimulated recall interviews, to investigate important aspects of faceted search interface use, specifically: (a) searcher gaze behavior--what components of the interface searchers look at; (b) how gaze behavior differs when training is and is not provided; (c) how gaze behavior changes as searchers become familiar with the interface; and (d) how gaze behavior differs depending on the stage of the search process. The results confirm previous findings that facets account for approximately 10-30% of interface use. They show that providing a 60-second video demonstration increased searcher use of facets. However, searcher use of the facets did not evolve during the study session, which suggests that searchers may not, on their own, rapidly apply the faceted interfaces. The findings also suggest that searcher use of interface elements varied by the stage of their search during the session, with higher use of facets during decision-making stages. These findings will be of interest to librarians and interface designers who wish to maximize the value of faceted searching for patrons, as well as to researchers who study search behavior.

  • the influence of search stage on gaze behavior in a faceted search interface
    ASIS&T '10 Proceedings of the 73rd ASIS&T Annual Meeting on Navigating Streams in an Information Ecosystem - Volume 47, 2010
    Co-Authors: Bill Kules, Robert Capra
    Abstract:

    This poster reports on a study of gaze behavior within a faceted Library Catalog. Initial results suggest that gaze behavior differs at definable stages within a search session.

  • a tale of two interfaces how facets affect the Library Catalog search
    Journal of the Association for Information Science and Technology, 2012
    Co-Authors: Sarah Ramdeen, Bradley M Hemminger
    Abstract:

    In the summer of 2008 all University of North Carolina libraries switched from a traditional Library Catalog interface supporting text-based searching (TextOnly) to a text and facet-based interface (TextFacet) to improve users' search experiences. This study seeks to understand the differences between these two interfaces and how they affect the search experience of the novice user. In this study, 40 participants were asked to search for resources using both interfaces. Their search times and accuracy were measured across three types of search tasks (known, partially known, and exploratory). After completing the searches, they were asked a series of questions about their experiences. The data were analyzed in order to identify strengths and weaknesses in both search interfaces. Thirty-six out of 40 participants preferred the TextFacet interface to the TextOnly interface. Using three dependent variables—time, accuracy, and rating—the two interfaces were compared and interactions were tested with the three task types. Search times for the TextFacet were shorter and participants preferred the TextFacet search interface over the TextOnly search interface. Performances across the three task types were different in terms of search time. The partially known and exploratory task types showed similar distributions for rating and accuracy. These distributions were distinctly different from the known task type. The results of this study may assist libraries in developing improved Library Catalog search interfaces that utilize facets as well as text searching.

  • effectiveness of real time query expansion in a Library Catalog
    Association for Information Science and Technology, 2011
    Co-Authors: Xi Niu, Bradley M Hemminger
    Abstract:

    Query expansion (QE) is a potentially effective technique to help searchers formulate or improve their search. In January 2010, the University of North Carolina at Chapel Hill (UNC) Library made an effort to improve user interactions with authority data in its online Catalog. It introduced a real- time query expansion feature for the Catalog interface that would provide real-time suggestions based on what the user had typed in the search box. QE is not a new technique, and has been widely used in web search interfaces. It has rarely been adopted by Library Catalogs though. From the libraries perspective, populating the query expansion feature with authority data provides a balance between traditional Library use of authority records and the expectations users have from their use of Web search engines. By analyzing the search logs from the Library server, we investigate the impact of this feature on users' search behavior. Two sampling periods of logs were chosen: April 2009 (before the feature's launch) and April 2010 (after the feature's launch). Totally, we have analyzed approximately 200M log data with approximately 800,000 useful log records. Results showed that users take the suggestions 20.26% of all searches. There was a significant increase in the rate of subject searches. The Library Catalog interface supporting dynamic query expansion also leads to longer queries, less query iterations per search, and fewer result items viewed per search. In addition, search failure rate has seen a great drop. However, results also imply some issues may exist with the use of query expansion, necessitating proper handling of the search expansion interface. Our findings have implications for how query expansions should be offered to Library Catalogs to increase the use of Library's collection.

  • Library Catalog analysis as a tool in studies of social sciences and humanities an exploratory study of published book titles in economics
    Journal of Informetrics, 2009
    Co-Authors: Daniel Torressalinas, Henk F Moed
    Abstract:

    Abstract This paper explores the use of Library Catalog Analysis (LCA), defined as the application of bibliometric or informetric techniques to a set of Library online Catalogs, to describe quantitatively a scientific-scholarly field on the basis of published book titles. It focuses on its value as a tool in studies of Social Sciences and Humanities, especially its cognitive structures, main book publishers and the research performance of its actors. The paper proposes an analogy model between traditional citation analysis of journal articles and Library Catalog Analysis of book titles. It presents the outcomes of an exploratory study of book titles in Economics included in 42 academic Library Catalogs from 7 countries. It describes the process of data collection and cleaning, and applies a series of indicators and thematic mapping techniques. It illustrates how LCA can be fruitfully used to assess book production and research performance at the level of an individual researcher, a research department, an entire country and a book publisher. It discusses a number of issues that should be addressed in follow-up studies and concludes that LCA of published book titles can be developed into a powerful and useful tool in studies of Social Sciences and Humanities.
