ABSTRACT Digital libraries and collections are a growing facet of today's traditional library. Digital library technologies have become increasingly more sophisticated in the effort to provide more and better access to the collections they contain. The evaluation of the usability of these technologies has not kept pace with technological developments, however, and the end-user has in some cases been left behind. This research study evaluates the usability of digital collections created using the CONTENTdm Digital Collection Management System, a software system used by the University of North Carolina at Chapel Hill. Specifically, this study addresses the following questions: Does CONTENTdm meet users' needs? Is the interface sufficiently intuitive for them to use it? Is the experience of exploring digital collections using CONTENTdm satisfying to users? Employing usability testing techniques with actual-end users, this study attempts to assess the efficacy of the CONTENTdm public interface as well as user attitudes toward it. Ten participants from three user groups—faculty, library science graduate students, and the general public—performed eleven tasks designed to test the key functions of CONTENTdm-created collections and then answered a series of questions about their experiences. Key findings from this study indicate that while the included digital collections are useful and desirable to end-users, the interface generated by CONTENTdm can be confusing even for those who have considerable experience using the Internet. Results from this study may be used to improve this software system and add to the literature surrounding the usability of digital libraries in general. 相似文献

There is ongoing discussion about the value and reliability of information produced by experts and organized by digital libraries in universities versus information produced by the crowd in virtual communities. This study compares users' perceptions of digital libraries and virtual communities in terms of affinity. In this study, affinity with digital libraries or virtual communities is defined as the degree of importance that users place on digital libraries or virtual communities. Data collected from 334 users of digital libraries and virtual communities were used for data analysis. The statistical method of 'compare means' is employed. We find the mean of affinity with digital libraries is significantly larger than that of virtual communities, suggesting users are likely to perceive higher levels of affinity with digital libraries than with virtual communities. More analysis oriented to different groups is also conducted. The findings and their implications are discussed. 相似文献

Digital library research has developed over the past decade, but little has been done on the identification of evaluation criteria, especially from users' perspectives. This article identifies users' criteria and applies them to the evaluation of existing digital libraries. Forty-eight subjects were instructed to develop and justify a set of essential criteria for the evaluation of digital libraries. At the same time, they were requested to evaluate existing digital libraries by applying the criteria that they were developing. A compilation of criteria developed by participants show that usability and collection quality were the most important criteria for evaluating digital libraries. Service quality, system performance efficiency, and user opinion solicitation were also deemed essential criteria. The author further compares digital library evaluation criteria identified by users and researchers and applied in previous research. The article reveals problems in current digital library design and development, discusses suggestions for improving digital library design, and presents areas for further research. 相似文献

A cross-cultural comparison of Kuwaiti and British citizens' views of e-government interface quality
It is difficult to conceive how Web users from different cultures can be encouraged to reap the benefits of an e-government initiative when its portal is suffering from culture-indifferent interface quality. Thus far, the e-government literature not only has paid scanty attention to web evaluation issues but also has been slow to embarking on cross-cultural research. As an attempt to address this concern, this investigation introduces an augmented approach to analyze cross-cultural website quality. The proposed approach consists of three parts: 1) a qualitative study of the website using content analysis, 2) an empirical evaluation using traditional statistical methods of perceptions of website users, and 3) a “persuasive quality gap” analysis that examines the gap between the composite scores of perceived importance and performance of quality attributes across the studied two cultures. These analyses were used to identify cross-cultural differences between Kuwaiti and British users' perceptions of e-government quality attributes. While the findings showed no significant differences between Kuwaiti and British users in terms of important quality features, the results revealed significant variations between the two groups in terms of perceived performance of quality attributes. Moreover, although the findings showed marginal support for the existence of differences between the two samples in terms of persuasive quality features, a post-hoc analysis of the persuasive quality gap revealed a need to consider not only important and/or high performing characteristics but also persuasive features to fully understand cross-cultural e-government quality variations. The author discusses the implications of these results for e-government design practices and future research. 相似文献

This study investigates comparative optimism—whereby people perceive themselves as relatively invulnerable to risks as compared to others—in the evaluation of online information credibility by children and their parents. Results of a representative national survey of Internet users revealed significant antecedents of children's and parents' comparative optimism, including demographic characteristics, cognitive thinking style, and perceived self-efficacy. Parental optimism was also found to relate to the mediation strategies used to regulate children's Internet use, and comparative optimism in children was associated with tendencies to believe online information and specific evaluation behavior. Findings are considered in terms of their theoretical implications and with regard to the role of parents in children's digital information literacy development. 相似文献

Libraries, along with other information service institutions, have entered a digital era in which resources are presented electronically through various digital platforms. The library Web site functions as the main source of information to patrons as well as a community outreach tool. Many library services now either succeed or fail based on how well users interact with the institution's Web site. In order to evaluate the effectiveness of library services, it thus becomes important for libraries to measure the performance of library Web sites. Web analytics is the ideal tool to answer questions regarding the evaluation of Web site performance. However, Web analytics can be hard to understand for those who do not have the time to familiarize themselves with all the terms and data. Writing a thorough Web analytics report can help make Web analytics easier to digest for administrators or Web site stakeholders.This tutorial provides step-by-step instructions on how to craft a Web analytics report. It provides suggestions on visualizing statistics, interpreting data, and customizing the report based on a real experience. The tutorial is facilitated with customized figures, charts, and tables from a real Web analytics report on the Texas Tech University Libraries Web site and concludes with recommendations on presenting the report to the administration and stakeholders. 相似文献

Creating a learnable, effective, and user-friendly library Web site hinges on providing easy access to search. Designing a search interface for academic libraries can be particularly challenging given the complexity and range of searchable library collections, such as bibliographic databases, electronic journals, and article search silos. Library Web designers must decide whether to present users with a single search interface—one that searches across content silos by default—or to offer an interface that exposes the various silos available. Designers must also contend with the user's entire search experience and determine how search should appear on the library home page as well as in global navigation systems. In the spring of 2010, the North Carolina State University Libraries sought to answer search design questions for an upcoming Web site design effort. The Libraries evaluated two different search interfaces to determine whether a tabbed search approach with options to pre-select silos is an effective design for end users. Findings show that a tabbed search interface is an effective design device for presenting multiple silos. This study outlines the methods the North Carolina State University Libraries used to conduct usability testing as well as observations, findings, and recommendations about effective design of search on academic library Web sites. 相似文献

The questions of whether chat reference service is beneficial enough to users to justify the costs of offering it, and how valuable it is to users in fulfilling their information needs, have been primary concerns for librarians providing the service, for library administrators managing the service, and for funding agencies paying for it. The present study combines a traditional evaluation of the user's satisfaction with the reference encounter, with details of the user's information use and the user's motivation for using the chat reference service. This evaluation study assesses the effectiveness of chat reference service in meeting users' information needs. 相似文献

Emma Hughes 《Health information and libraries journal》2016,33(1):77-81
This article is the first in the feature to highlight the social network site Twitter as a tool for health information and it reports on a study by Emma Hughes, who completed an MSc in information and library studies at Aberystwyth University in 2014. Emma's research investigated the quality of health information available on Twitter, in particular the information available on UK alcohol consumption guidelines. Her research suggests that users searching for this information would need certain literacy skills to interpret it correctly. However, there is no doubt that Twitter is an increasingly popular resource for information dissemination and health professionals, and organisations should be encouraged to use it frequently as a tool for sharing information.

A number of technologies exist which enable the unobtrusive capture of computer interface interactions in the background of a user's working environment. The resulting data can be used in a variety of ways to model aspects of search activity and the general use of electronic documents in normal working routines. In this paper we present an approach for using captured data to identify relationships between documents used by an individual or group, representing their value in a given context—that may relate to specific information need or activity. The approach employs the use of a naïve Bayesian classifier to evaluate possible relationships that are derived implicitly from the data. It is intended that the relationships established be stored within an information retrieval (IR) system to aid in the retrieval of related documents where future users arrive at a similar context. In the evaluation of the approach over 70 hours of data from computer users in industrial and academic settings are collected to assess its overall feasibility. The results indicate that the approach provides a useful method for the establishment of identifiable relationships between documents based on the context of their usage, rather than their content. 相似文献

This research explored the perceptions of university students about the credibility of information being shared on Facebook. The data were collected using an online questionnaire from university students who were Facebook users. A total of 325 usable responses were received which were analyzed using SPSS. The results revealed that these students perceive information shared on Facebook as credible and of good quality. The source credibility, medium credibility, and information quality had positive and significant relationships with each other. The age, social background, and educational level of students appeared to predict the credibility of information shared on Facebook. These results are useful for information professionals and social media managers in extent to understand and cater to the demands of information consumers. These findings would also be helpful for teachers, information providers, and researchers to understand the perspectives of developing countries' students on the credibility of social media information. Furthermore, this study is supposed to be a valuable addition in existing literature which could provide guidelines for novice researchers, interested in exploring the area, especially in the context of Facebook users in a developing country's context. 相似文献
