随着网络的发展,网络信息资源保存变得越来越迫切。作为信息的传播者,网络出版者在web资源保存中发挥着重要的、不可替代的作用。当前,网络出版者既受到知识产权的保护,又面临着世界各国不断发展的网络出版物呈缴制度的压力。同时,他们还肩负着网络信息短期保存、与保存机构合作、信息提供和信息发掘等责任。在这个过程中,网络出版者同样会获得诸如网站宣传、经济效益、信息和服务等方面的收获。 相似文献

Web2.0是相对Web1.0的新一类互联网应用的统称,它强调用户的广泛参与;语义Web作为当前Web技术的扩展,通常被看作新一代的信息基础设施,被人们称为第三代智能网络。目前,关于二者的研究和争论如火如荼,笔者认为二者在Web的演进过程中是相辅相成、互相支持的。本文分析了二者各自的局限,阐述了二者结合的基本原理,最后以实例绘制了二者结合的具体实现方法。 相似文献

Objectives:
The research evaluated participant satisfaction with the content and format of the “Web 2.0 101: Introduction to Second Generation Web Tools” course and measured the impact of the course on participants'' self-evaluated knowledge of Web 2.0 tools.Methods:
The “Web 2.0 101” online course was based loosely on the Learning 2.0 model. Content was provided through a course blog and covered a wide range of Web 2.0 tools. All Medical Library Association members were invited to participate. Participants were asked to complete a post-course survey. Respondents who completed the entire course or who completed part of the course self-evaluated their knowledge of nine social software tools and concepts prior to and after the course using a Likert scale. Additional qualitative information about course strengths and weaknesses was also gathered.Results:
Respondents'' self-ratings showed a significant change in perceived knowledge for each tool, using a matched pair Wilcoxon signed rank analysis (P<0.0001 for each tool/concept). Overall satisfaction with the course appeared high. Hands-on exercises were the most frequently identified strength of the course; the length and time-consuming nature of the course were considered weaknesses by some.Conclusion:
Learning 2.0-style courses, though demanding time and self-motivation from participants, can increase knowledge of Web 2.0 tools.Highlights
- Course participants'' knowledge of Web 2.0 tools increased significantly.
- Medical Library Association members liked the online course format, particularly the hands-on exercises and self-pacing.
- There was no significant difference in course completion rate or course satisfaction among participants from academic, hospital, or other library settings.
- Few survey respondents pointed specifically to workplace technology blocking as a reason for non-completion, though this underestimates the effect of such blocking on hospital and corporate library staff.
Implications
- MLA members appreciate having online continuing education (CE) courses. New short, online CE courses were developed based on the findings of this survey.
- Hands-on exercises may improve learning and increase motivation.
- Time and self-motivation are necessary for completing online courses.

SUMMARY Key trends and players are changing the information content industry. In her keynote address to NASIG, Leigh Watson Healy provided a “20,000-foot” view of the content industry past, present, and future. Drawing from her experience in the field of educational information and from research conducted by Outsell, Inc., a marketing and research firm focusing on all aspects of the information content industry, Healy invited the audience to challenge the assumptions presented, and encouraged NASIG members to think about the dramatic changes in store for vendors, buyers, and end users of information. 相似文献
