AbstractThis study aims to identify, collect and critical review the research literature on Multilingual Digital Libraries in English language from 1997 to 2012.Design/methodology/approach: The present literature review has followed the rules of systematic review. In particular, the identified relevant papers were categorized based on their expressed aim on two core themes, that of system-centered and user-centered studies. The assigned papers were further analyzed and six sub-themes emerged for the system-centered studies and four for the user-centered studies. Additional categorization was also provided according to type of publication.Findings: The literature concerning Multilingual Digital Libraries is vast and mainly focuses on two aspects the “System” and the “Users”. The majority of papers tried to meet the challenges raised for enabling multilingual information retrieval in Digital Libraries. Unfortunately, these efforts undertaken by a small number of researchers or research groups apparently working in isolation and therefore resulting in the development of numerous different tools and techniques. Relatively few studies have focused on the user and aimed to explore users' behavior and expectations when interacting with Multilingual Digital Libraries. As a result, further research is needed to reach to some tangible and usable findings.Originality/value: This literature review captures the diversity of the research conducted regarding multilingual information access and retrieval in Digital Libraries. It organizes the vast literature in comprehensive themes and sub-themes enabling easy access to specific information.Limitations: This study reviews only papers in English due to language restrictions from 1997 to 2012. 相似文献

Librarians at the State University of New York at Buffalo implemented the Resources for International Students Web guide to support library outreach to a multicultural and multilingual audience. A focus group helped librarians to understand the needs of new international students and tailor Web resources accordingly. In addition to creating awareness of international student cultural challenges, this article presents focus-group guidelines to assist in the planning process of library services and resources. 相似文献

Abstract In 2002, librarians at the Utah State University (USU) Libraries were awarded a grant to develop online tutorials. The major design challenge was to create tutorials specific to USU resources and students, including distance learners, while also making them flexible so that other Utah colleges and universities can adapt them for their own needs. The tutorials also needed to address the information behavior of a new generation of students accustomed to using computers and the Internet. While recent studies have begun to address some gaps in our knowledge of the information behavior of the Web Generation, we conducted a needs assessment to help us create a tutorial that more accurately addresses the existing knowledge and behavior of undergraduates at USU. We used multiple methods to determine the learning needs of our audience and to provide guidance for the design process. 相似文献

This investigation sought to develop a broad view of discovery service user behavior by analyzing vendor-provided and Google Analytics usage data from discovery service implementations at two Indiana University campuses. The results of this analysis demonstrate how usage data can communicate both intermediary and end results of user interactions within discovery services. The findings reveal user behavior trends, which may be used to develop strategies to improve information literacy instruction techniques, as well as discovery service interface enhancements. 相似文献

Specific stereotype portrayals of African American women were hypothesized to produce stereotype-consistent judgments made of a different African American woman. Participants (N?=?76) observed a mammy, jezebel or welfare queen video-segment. Then they observed an African American woman in a mock job interview and rated the interviewee. Participants who observed a specific stereotype associated the interviewee more quickly with stereotype-consistent adjectives than with stereotype-inconsistent adjectives for all three stereotypes. For measures of how suitable the woman was for jobs that were related to the stereotypes, only the welfare queen prime produced significant effects. 相似文献

The study reported herein aimed to identify and discuss the nature and pattern of the uses of new media through a notable YouTube phenomenon. It analyzed 132 online videos centered on ‘Bus Uncle,’ a YouTube celebrity who rose into fame in Hong Kong during April 2006. Most of the videos drew references from local popular culture texts. They were mostly playful and sarcastic in their undertones. The collective behaviors in YouTube suggest that this hugely popular video-sharing site takes on the roles as public space, a playground and a cultural public sphere. 相似文献

Our neighborhoods are full of life. This life flows into and through our libraries. The cares, worries, joys, and pleasures of everyday living accompany these visits. Members of these communities may walk in, be pushed in, and sometimes perhaps, skate in. Those of us who work in their libraries are the beneficiaries. The stories of some of these neighbors as they use the Colonial Heights, Elk Grove, and Fair Oaks branches of the Sacramento Public Library are conveyed in this anecdotal‐based article. 相似文献

ABSTRACT Uncertainty is defined as affective symptoms of stress, anxiety, and frustration when faced with an information need. Traditional face-to-face instruction allows sender and receiver to fulfill information needs using multiple sources, which can be visual, auditory, tactile, or verbal. Distance learners may experience high levels of uncertainty when most or all of the communication and interaction takes place in an electronic environment that does not allow for these multiple information sources. Research on face-to-face communication and uncertainty suggests that people attempt to reduce uncertainty by acquiring more information and also by using structured or familiar information resources. This paper suggests that many of our behavioral motivations in face-to-face activities would also apply in the online environment. By creating online tutorials that combine structured hierarchical instructions with familiar modes of communication, we may be able to reduce symptoms of uncertainty in the library search process. 相似文献
