- Abstract
- We present the first systematic study of the influence of time on user judgements for rankings and relevance grades of web search engine results. The goal of this study is to evaluate the change in user assessment of search results and explore how users' judgements change. To this end, we conducted a large-scale user study with 86 participants who evaluated 2 different queries and 4 diverse result sets twice with an interval of 2 months. To analyze the results we investigate whether 2 types of patterns of user behavior from the theory of categorical thinking hold for the case of evaluation of search results: (a) coarseness and (b) locality. To quantify these patterns we devised 2 new measures of change in user judgements and distinguish between local (when users swap between close ranks and relevance values) and nonlocal changes. Two types of judgements were considered in this study: (a) relevance on a 4-point scale, and (b) ranking on a 10-point scale without ties. We found that users tend to change their judgements of the results over time in about 50% of cases for relevance and in 85% of cases for ranking. However, the majority of these changes were local.

- Abstract
- Die Arbeit untersucht die Usability von Online-Wörterbüchern und elektronischen Sprachportalen und soll eine Brücke zwischen der Usability von Websites hinsichtlich softwareergonomischer Normen und Konventionen und Wörterbüchern in elektronischer Form schlagen. Die einzige Usability-Methode, mit der es möglich ist, konkrete und empirisch belegte Aussagen darüber zu treffen, wie potentielle Nutzer ein Online-Wörterbuch verwenden und welche Probleme dabei festgestellt werden, ist ein Usability- Test mit realen Benutzern. Als Untersuchungsgegenstand dient das Online-Wortschatz-Informationssystem Deutsch (Owid), die Base lexicale du français (BLF) und das elektronische Lernerwörterbuch Deutsch-Italienisch (Eldit). Die Arbeit setzt sich aus vier verschiedenen empirischen Studien zusammen. Da ein Usability-Test immer nur einen Ausschnitt an Funktionalitäten aus einem gesamten System widerspiegeln kann, wurden mithilfe einer empirischen Fragebogen-Studie zunächst die für den Benutzer wichtigsten und am meisten verwendeten Funktionen eines Online-Wörterbuchs identifiziert und als Grundlage für den Test gewählt. Eine anschließende heuristische Evaluation trug potentielle Usability-Probleme der drei Online- Wörterbücher zusammen und stellte die Grundlage für die Thesenstellung des Usability-Tests dar. Der Test setzte sich aus zwei empirischen Teilen zusammen: Einem Aufgabenteil, den die Testperson für jedes der drei Online-Wörterbüchern einzeln bearbeiten und dabei die Testmethode des lauten Denkens anwenden musste und einem Post-Test- Fragebogen, der direkt nach dem Bearbeiten des jeweiligen Aufgabenkatalogs ausgefüllt wurde. Der gesamte Test wurde mit Morae, einer Software u. a. für Software- und Website- Usability-Tests, durchgeführt und ausgewertet.

- Abstract
- This study examined how searchers interact with a web-based, faceted library catalog when conducting exploratory searches. It applied multiple 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.

- Abstract
- People frequently answer consequential questions, such as those with a medical focus, using Internet search engines. Their primary goal is to revise or establish beliefs in one or more outcomes. Search engines are not designed to furnish answers, and instead provide results that may contain answers. Information retrieval research has targeted aspects of information access such as query formulation, relevance, and search success. However, there are important unanswered questions on how beliefs-and potential biases in those beliefs-affect search behaviors and how beliefs are shaped by searching. To understand belief dynamics, we focus on yes-no medical questions (e.g., "Is congestive heart failure a heart attack?"), with consensus answers from physicians. We show that (a) presearch beliefs are affected only slightly by searching and changes are likely to skew positive (yes); (b) presearch beliefs affect search behavior; (c) search engines can shift some beliefs by manipulating result rank and availability, but strongly-held beliefs are difficult to move using uncongenial information and can be counterproductive, and (d) search engines exhibit near-random answer accuracy. Our findings suggest that search engines should provide correct answers to searchers' questions and develop methods to persuade searchers to shift strongly held but factually incorrect beliefs.
