BACKGROUND: The analysis included forty-one academic health sciences library (HSL) Websites as captured in the first two weeks of January 2001. Home pages and persistent navigational tools (PNTs) were analyzed for layout, technology, and links, and other general site metrics were taken. METHODS: Websites were selected based on rank in the National Network of Libraries of Medicine, with regional and resource libraries given preference on the basis that these libraries are recognized as leaders in their regions and would be the most reasonable source of standards for best practice. A three-page evaluation tool was developed based on previous similar studies. All forty-one sites were evaluated in four specific areas: library general information, Website aids and tools, library services, and electronic resources. Metrics taken for electronic resources included orientation of bibliographic databases alphabetically by title or by subject area and with links to specifically named databases. RESULTS: Based on the results, a formula for determining obligatory links was developed, listing items that should appear on all academic HSL Web home pages and PNTs. CONCLUSIONS: These obligatory links demonstrate a series of best practices that may be followed in the design and construction of academic HSL Websites.  相似文献

Course-related library Web pages can be designed to introduce students to an academic library Web site and provide access to information relevant to specific courses. These pages are most often developed to support a library instruction session. The author's course-related pages are designed on a template that includes the main features of the library Web site (e.g., links to the online catalog, reference information, and interlibrary loan request forms), a list of pertinent online indexes and databases, links to electronic journals, and recommended Web sites. Technical and organizational issues related to creating and maintaining such pages are discussed, as are outreach efforts and faculty/student response to incorporating this type of Web page into library instruction. A sample evaluation form and a list of selected course-related library Web sites are included as appendices.  相似文献

The exponential growth of federal Websites is outpacing federal information management policy guidelines. Federal Websites are potentially rich information resources, and the Web may well become the preeminent channel for disseminating federal information. Legitimate policy issues associated with the use of this new information dissemination channel should be assessed. This article provides an overview of information policy issues which affect federal Websites and introduces assessment techniques which federal Website designers and administrators could use to evaluate the design and management of their Web-based information resources.  相似文献

从大量动态无序的非结构化网络资源中发现主题或学科核心网站,是学科导航、个性化服务及信息推送的基础。但在核心网站评选过程中,存在两个问题,一是通过搜索引擎获得的相关网站集合中,有大量非相关网站,直接影响核心网站评选的效率;二是当前核心网站研究中均未考虑到网站的扩展问题。为此,本文将Web共引分析技术引入非相关网站过滤,提出利用Fisher判别法实现核心网站扩展,并给出了扩展可靠性检验方法。  相似文献

OBJECTIVES: This paper explores the potential of multinomial logistic regression analysis to perform Web usage mining for an academic health sciences library Website. METHODS: Usage of database-driven resource gateway pages was logged for a six-month period, including information about users' network addresses, referring uniform resource locators (URLs), and types of resource accessed. RESULTS: It was found that referring URL did vary significantly by two factors: whether a user was on-campus and what type of resource was accessed. CONCLUSIONS: Although the data available for analysis are limited by the nature of the Web and concerns for privacy, this method demonstrates the potential for gaining insight into Web usage that supplements Web log analysis. It can be used to improve the design of static and dynamic Websites today and could be used in the design of more advanced Web systems in the future.  相似文献

Hyperlinks from other Web sites are, in some respect, similar to bibliographical citations. Link analysis, like citation analysis in bibliometrics, has emerged as a research area of webometrics in recent years. But why are links made and where do they point? A sample of inlinked Web entities (i.e., Web pages or Web sites) was randomly selected from a group of academic institutions' Web sites. The inlinked sites, along with the hyperlink data and outlinking sites, were analyzed and categorized to form a taxonomy of inlinked sites. Based on this taxonomy, a list of reasons for hyperlinking, grouped in four top-level categories (teaching/learning, research, service, and home page), was identified. Compared with bibliographical citations, hyperlinks were made for a different set of reasons. Hyperlinking also has fewer dimensions, less complexity, and little negative implication. On the whole, almost 50% of all the inlinks examined were created for pointing to resource or directory information provided at the target Web sites. In addition, nearly three fourths (73%) of all the inlinked sites analyzed in this study were linked to for reasons relating to service or home page while less than one third (27%) of the links were made out of research or teaching/learning motivations. Yet, teaching and research are the two major criteria traditionally used for evaluating academic institutions. These findings, although by no means conclusive, suggest that evaluative link-based studies should not only consider link counts but also reasons for hyperlinking in order to ensure the validity of such research.  相似文献

Unlike Web hyperlink data, Web traffic data have not yet been the focus of considerable study in Webometrics research. The relationships between Web traffic data and academic/business performance measures have not been as firmly established as the relationships between Web hyperlink data and such performance measures. Although various traffic data sources exist, few studies have examined and compared their relative merits. We carried out a study that aimed to address this lack. We selected groups of universities and businesses from the U.S. and China and collected their Web traffic data from three sources: Alexa Internet, Google Trends for Websites, and Compete. We found significant correlations between Web traffic data and organizational performance measures, specifically academic quality for universities and financial variables for businesses. We also examined the characteristics of the three data sources and compared their usefulness. We found that Alexa Internet outperformed the others.  相似文献

ABSTRACT

As the World Wide Web has advanced since its inception, librarians have endeavored to keep pace with this progress in the design of their library Web pages. User recommendations collected from focus groups and usability testing have indicated that the University of Scranton's Weinberg Memorial Library's Web site was not working as intended, and the library's home page, in particular, was cluttered. Focus groups indicated that the process of accessing the library's databases from off-campus took too many steps, key resources were not located in key areas of the page, links were too close together, and the font was too small. Library staff determined it was necessary to rethink and redesign its pages. Self-reports from focus groups were insufficient to get at the mechanics of Web page use. Through usability testing, librarians were able to observe students and faculty completing simple research and directional tasks. Before “going live” with the new page in January 2007, users who had participated in the focus groups and in the usability testing were surveyed about the redesigned library Web page. The users indicated that the new Web page was less confusing, easier to use, and somewhat more intuitive than the previous library Web page. Web sites are always works in progress, and academic librarians should be proactive about making changes to their library Web sites to take advantage of emerging technology and to meet user expectations.  相似文献

This article is intended to serve as a guide for librarians developing mobile Websites to be linked to their current library Website. Kroski (2008a) defines the mobile Web as “the World Wide Web accessed through a mobile device, ranging from a cellular phone to an iPod Touch. It includes the entirety of the Web and is not limited to Websites that are specifically designed for mobile viewing” (5). This literature review focuses on the mobile Web, mobile device usage, and best practices for designing mobile Websites for libraries.  相似文献
