The Web has evolved as a hypertext environment whose value is derived from a simple ability to link resources together. The advanced linking features of some early hypertext systems might be implemented in the Web in various ways. The Semantic Web is one aspect of the continuing evolution of the Web which may be of value to the evolution of scholarly publishing and research, and may enable publishers to justify investment in the future. The key advantages are the ability to unlock value from the existing scholarly literature by enabling innovation in research tools; further encouraging the creation of a marketplace of services of value to the publishing industry; and ensuring that websites and content are well integrated into the Web as it exists now and in the future. 相似文献

ABSTRACTThe primary purpose of an academic library Web site is to serve as a portal to library-acquired content. Navigational design of a library Web site affects the user's ability to find and access content. At Albertsons Library, the goal of the navigational design of the Web site is to mimic user behavior on the Web site to help them access information and articles from over 300 different library vendors. Coordinating with different vendors makes tracking the navigational flow of user behavior difficult with the tool Google Analytics. Using the events feature in Google Analytics, the team responsible for Web design was able to track user flow, and was able to quantify how many users were actual “drop-offs” versus those that were clicks into library resources. Decisions made after acquiring these data resulted in a Web site with a 10 percent or less bounce rate, and decreased the number of clicks required for users accessing the library's content. 相似文献

Google is the single largest driver of traffic to library Web sites and digital repositories, and librarians would do well to listen when the search giant reveals information about its practices or makes recommendations. Recently, Google announced that it would begin to favor Web sites that use the secure hypertext transfer protocol (HTTPS) in its search results rankings. HTTPS encrypts data transmission and one of Google's stated reasons for this change is to help make the Web safer and minimize data theft. Similar announcements by Google have sometimes been ignored by librarians, to the peril of the visibility and use of library products and services on the Web. 相似文献

网络超文本阅读研究——基于大学生网络阅读行为的调查分析 总被引:1,自引:0,他引:1
朱咫渝 《图书馆工作与研究》2011,(10)
随着互联网的兴起,以非线性链接、跳跃、开放性、超媒体等为特征的网络超文本阅读成为大众阅读最主要的一种方式之一。为了了解网络超文本阅读与纸本阅读的差异;分析超文本对阅读及信息搜寻行为的影响,本研究利用问卷调查法和个人访谈法,对大学生的网络阅读行为进行实证调查,研究发现虽然超文本阅读将阅读范围从文字材料扩大到多媒体,实现了读者与作者的互动交流,更有利于信息搜寻,但这种倾向于快速浏览的阅读同时也带来了阅读的迷失感,而且面对与学业相关的阅读时仍以纸本阅读为主。 相似文献

This study explores faculty deposits in institutional repositories (IR) within selected disciplines and identifies the diverse navigational paths to IR sites from library Web site homepages. The statistical relationship between the development of an IR and the presence of a Web site dedicated to the reform of traditional scholarly communication is also explored. The implications for the development of institutional repositories are highlighted. 相似文献
