The four FRBR user tasks have become widely accepted as functions of the library catalog, but there have been only sporadic discussions concerning their validity and sufficiency, despite their modification in the models subsequently presented in the FRAD, FRSAD, and draft FRBR-LRM reports. This article presents a critique of the four variant sets of user tasks, and proposes an extended set of six generic end-user tasks, applicable to both bibliographic and authority data: locate, collocate, connect, identify, select, and obtain. The article also outlines their interrelationships and suggests those tasks that may be particularly well supported by professional cataloging. 相似文献

音频资料元数据规范与FRBR的应用* 总被引：4，自引：1，他引：4
王绍平 《现代图书情报技术》2004,20(9):21-23
制定音频资料元数据规范需要正确界定著录对象，确定它们之间的关系，同时根据著录对象的特征及其被用户利用的特点，明确元数据的构成元素。FRBR提出的文献信息资源的实体层次有助于根据资源的特征与用户需求，选择适当的描述层次，确定相应的元素构成。FRBR模型的立体架构也为构建元数据提供了新的思路。 相似文献

IFLA书目记录功能需求(FRBR)初探 总被引：28，自引：1，他引：27
IFLA的书目记录功能需求(Functional Requirements for Bibliographic Records,简称FRBR)是目前国际书目控制的焦点,它利用实体--属性方法构建了一个揭示书目结构和关系的概念模型。该模型对沿袭了一个多世纪的编目理论提出了挑战,在编目界引起了强烈反响。那么,FRBR的基本理念和精髓是什么?它对传统的编目规则和实践会产生什么影响?它的应用价值到底有多大?文章试图从这几个方面对FRBR进行介绍和探讨,以供国内同仁参考。 相似文献

ABSTRACTPrevious research has mostly focused on the demographic and academic correlates of library anxiety. This study focused on the “library anxiety” and “emotion perception” of students, with the objective of examining the relationship between these two concepts. In total, 279 self-reporting questionnaires were used for analysis. The results confirmed the existence of the phenomenon of library anxiety, with these students being more anxious regarding the “user education” and “user knowledge” factors. They showed greater skills of emotion perception. A negatively significant relationship appeared between library anxiety and emotion perception. The results suggest that user education and emotion perception training programs should be developed to overcome students' problems. 相似文献

This study examines the conceptions and treatment of genre in four sets of modern Anglo-American cataloging rules spanning 171 years. Genre-related rules are first identified through “genre(s),” “form(s),” and “type(s)” keyword searches, and manual examination of the contents, then analyzed by level of treatment genre receives and by user tasks, as defined in the Functional Requirements for Bibliographic Records. While genre is found to be sporadically addressed across the rules, its significance has increased over time. In conclusion, the authors call for a rigorous and functional definition of genre and an integrated approach to genre in cataloging. 相似文献

Crowdsourcing interactions: using crowdsourcing for evaluating interactive information retrieval systems 总被引：1，自引：0，他引：1

In the field of information retrieval (IR), researchers and practitioners are often faced with a demand for valid approaches to evaluate the performance of retrieval systems. The Cranfield experiment paradigm has been dominant for the in-vitro evaluation of IR systems. Alternative to this paradigm, laboratory-based user studies have been widely used to evaluate interactive information retrieval (IIR) systems, and at the same time investigate users’ information searching behaviours. Major drawbacks of laboratory-based user studies for evaluating IIR systems include the high monetary and temporal costs involved in setting up and running those experiments, the lack of heterogeneity amongst the user population and the limited scale of the experiments, which usually involve a relatively restricted set of users. In this paper, we propose an alternative experimental methodology to laboratory-based user studies. Our novel experimental methodology uses a crowdsourcing platform as a means of engaging study participants. Through crowdsourcing, our experimental methodology can capture user interactions and searching behaviours at a lower cost, with more data, and within a shorter period than traditional laboratory-based user studies, and therefore can be used to assess the performances of IIR systems. In this article, we show the characteristic differences of our approach with respect to traditional IIR experimental and evaluation procedures. We also perform a use case study comparing crowdsourcing-based evaluation with laboratory-based evaluation of IIR systems, which can serve as a tutorial for setting up crowdsourcing-based IIR evaluations. 相似文献

Retaining users of mobile government services (MGS) is critical to the success of mobile government. Drawing on Bagozzi's self-regulation framework, the current research investigates the predictors of MGS continuance by considering both perceived quality and perceived value. Unlike most e-government research that has utilized linear models, this study employed a two-stage structural equation modeling–artificial neural network approach that can identify non-linear and non-compensatory interactions. The current research first applied a structural equation model to examine the significant factors influencing MGS continuance, and then utilized a neural network model recheck the structural equation modeling findings and rank the importance of these factors. Data were obtained from 335 “one-stop-shop service platform” app users in China through an online survey platform. The research findings reveal that user satisfaction is the utmost influential determinant of their continuous-use intention regarding MGS, followed by user trust; moreover, perceived quality and perceived value strongly influence satisfaction and trust. However, perceived risk does not affect intention to continue use. We also discuss theoretical and practical implications for government agencies and service providers, for improving user continuance rates for MGS. 相似文献

This article contends that not only journalism but also journalism studies can benefit from a stronger commitment to the public. While the bodies of literature on “popular journalism”, “public journalism” and “citizen/participatory journalism” have, in different contexts and from different angles, made a strong case in favour of a public-oriented approach to journalism, it is remarkable how few of the empirical studies on journalism are based on user research. As the control of media institutions over the news process is in decline, we should take the “news audience” more seriously and try to improve our understanding of (changing) news use patterns. Besides this rather obvious theoretical point, there are also societal and methodological arguments for a more user-oriented take on the study of journalism. Starting from a reflection on the key trends in news use in the digital age—participation, cross-mediality and mobility—this article attempts to show the theoretical and societal relevance of a radical user perspective on journalism and journalism research alike. Furthermore, we look at new methodological opportunities for news user research and elaborate on our arguments by way of an empirical study on changing news practices. The study uses Q-sort methodology to expose the impact a medium's affordances can have on the way we experience news in a converged and mobile media environment. The article concludes by discussing what the benefits of a radical user perspective can be both for journalism studies as for journalism. 相似文献

The classical Probability Ranking Principle (PRP) forms the theoretical basis for probabilistic Information Retrieval (IR)
models, which are dominating IR theory since about 20 years. However, the assumptions underlying the PRP often do not hold,
and its view is too narrow for interactive information retrieval (IIR). In this article, a new theoretical framework for interactive
retrieval is proposed: The basic idea is that during IIR, a user moves between situations. In each situation, the system presents
to the user a list of choices, about which s/he has to decide, and the first positive decision moves the user to a new situation.
Each choice is associated with a number of cost and probability parameters. Based on these parameters, an optimum ordering
of the choices can the derived—the PRP for IIR. The relationship of this rule to the classical PRP is described, and issues
of further research are pointed out.

This article investigates user experiences with editorial control in online newspaper comment fields following the public backlash against online comments after the 2011 terror attacks in Norway. We analyze data from a survey of online news consumers focusing on experiences and attitudes towards editorial control set against a spectrum between “interventionist” and “noninterventionist” positions. Results indicate that interventionist respondents rate the quality of online comments as poor, whereas noninterventionist respondents have most often experienced being the target of editorial control measures and feel that editorial control has intensified after the terror attacks. We conclude that newspapers should pay attention to the different needs of participants when devising strategies for editorial control. Media professionals should also consider changes to increase the transparency of moderation practices. 相似文献
