    Abstract
    Examines the problem of a compelling online news delivery system by focusing on how mass media audiences and online users differ in their assessment of news. It employed a 2-wave USA national survey to study the perception of interactivity in mass media and computer networks and its relationship to the assessment of news. The 1st wave looked a national probability sample, ahile the 2nd targeted viewers of NBC Nightly News who responded to the show via e-mail. NBC respondents rated mass media to be less interactive, while they rated computer communication more interactive than the national sample. The NBC group also rated mass media news less important and of lower quality than did the national sample. Interactivity ratings did not predict mass media credibility assessment for either group. However, respondents who defined interactivity as cybernetic feedback or who contacted NBC by e-mail rated computer communication to be more credible than thos who did not

    Abstract
    The research described in this article extends work done on human behavior in naming concepts and objects by adapting a methodology developed at Bell Labs and applying it to a library indexing language, the Library of Congress Subject Headings. The study investigated the representation of users' knowledge (names of objects and concepts), database representation for similar objects and concepts, and degree of agreement among users and between users and information systems. Three user groups give names to 40 stumuli. Names generated were compared with each other and with LCSH. Degree of agreement was calculated using similarity measures. The analyses identified patterns of agreement and variability in naming. There was little agreement in the names people use and the names recommended for use by LC, implying that retrieval systems should do more to accomodate common naming behavior

    Abstract
    Knowing what information a user wants is a paramount challenge to information science and technology. Implicit feedback is key to solving this challenge, as it allows information systems to learn about a user's needs and preferences. The available feedback, however, tends to be limited and its interpretation shows to be difficult. To tackle this challenge, we present a user study that explores whether tracking the eyes can unpack part of the complexity inherent to relevance and relevance decisions. The eye behavior of 30 participants reading 18 news articles was compared with their subjectively appraised comprehensibility and interest at a discourse level. Using linear regression models, the eye-tracking signal explained 49.93% (comprehensibility) and 30.41% (interest) of variance (p < .001). We conclude that eye behavior provides implicit feedback beyond accuracy that enables new forms of adaptation and interaction support for personalized information systems.

    Abstract
    Finding audiovisual material for reuse in new programs is an important activity for news producers, documentary makers, and other media professionals. Such professionals are typically served by an audiovisual broadcast archive. We report on a study of the transaction logs of one such archive. The analysis includes an investigation of commercial orders made by the media professionals and a characterization of sessions, queries, and the content of terms recorded in the logs. One of our key findings is that there is a strong demand for short pieces of audiovisual material in the archive. In addition, while searchers are generally able to quickly navigate to a usable audiovisual broadcast, it takes them longer to place an order when purchasing a subsection of a broadcast than when purchasing an entire broadcast. Another key finding is that queries predominantly consist of (parts of) broadcast titles and of proper names. Our observations imply that it may be beneficial to increase support for fine-grained access to audiovisual material, for example, through manual segmentation or content-based analysis.

    Abstract
    Identifies and characterizes the knowledge used by experienced librarians while searching for subject information in online catalogues. 10 experienced librarians performed the same set of 6 subject searches in an online catalogue. Investigates the knowledge used to solve retrieval problems. This knowledge presents expertise in the use of the catalogue. Data were collected through the use of think aloud protocols, transaction logs and structured interviews. Knowledge was defined as knowledge objects (factual knowledge), knowledge of events (experimental knowlegde), knowledge of performance (process knowledge), and metaknowledge. Metaknowledge is the sense of whole derived from the integration of factual, process, and experimental knowledge about the search and the conditions under which it is performed. Focuses on metaknowledge. For evidence of metaknowledge the data were examined for explanations that participants gave for their actions and observations, and for ways that participants evaluated their own progress during the process of searching. Reasons and explanations given by searchers were related to all phases of the library information retrieval process from the user's receipt of material to policies for collection development, and not just events directly related to the performance of a particular search task

    Abstract
    Representation and retrieval obstacles within a digital library designed for use by middle school children are presented. Representation of objects is key to retrieval. Tools used to create representations for children's resources, such as controlled vocabularies, need to be more age appropriate. Development of age-appropriate controlled vocabularies requires us to learn more about the ways children interact with systems and form search strategies to represent their information needs. Children's search terms and questions are a rich resource for learning more about their information seeking process, their question state, and their formulation of searches. A method for gathering and using children's own search terms and the benefits of their utilization in developing more age-appropriate controlled vocabularies are discussed.

    Abstract
    The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.
