Web of Science数据库功能的作用.ppt

* Next are the “unique capabilities” that are provided within the Web of Science. We have been capturing, unifying and standardising Author Cited References over 55 years, and this allows unique methods of discovery simply not possible in any other literature database. It is possible to navigate backwards in time through the “Cited References” and forwards in time using the “Times Cited” hyperlinks to discover the complete story behind every single research activity. Discover the details of all of the prior work that made this discovery possible, but in addition you can also find the latest developments that have been built upon this discovery. Using the “Related Records” function. It is also possible to expand your search and find articles that are impossible to find through traditional searching techniques. * And the final benefit of the Web of Science is the Depth of the coverage. Going all the way back to 1945 in Sciences, 1956 in the Social Sciences and 1975 in the Arts Humanities, you can be sure of getting the complete history of any research topic. Although we recognize the importance of current information, we have found that some of the most influential research is often decades old, and without researching the historic records significantly you will be missing out on key information. * 被引文献检索（Cited Reference Search): 谁引用这篇论文？引用这篇论文的文献讲了些什么？ 论文之间的引文连接：反映了科学交流的网络、结构及其随时间的变化、学科间的互动 引文统计作为一种文献计量和科学计量的指标：告诉分析人员首先应该关注什么 科学研究贵在创新，一篇在严肃的科学期刊上发表的研究论文，必须在某些方面有所创新，否则就没有发表的价值。但是所有的科学研究又都是建立在前人工作的基础之上，在此基础上有所发展，因此又必需对前人工作给以充分的评价。在论文中必需充分回顾与本人结果直接有关的前人工作，然后再恰如其分地介绍自己工作中的创新之处… … - 邹承鲁，“我的科学之路”，2003年 * * * * Citation Index 的功能独特，检索者可以发挥其丰富的想象力，籍此解决许多问题： * * * 知识发现：信息已经成为社会发展的三大重要资源之一。我们处在这样一个信息时代，即我们几乎被信息淹没，但仍感到知识的匮乏，因为大量的信息垃圾充斥其中，使我们很难从中得到解决问题所需的知识。我们首先面对的是如何管理信息中的知识，如何从数据中获取知识，如何利用大量信息发现知识，这就是我们今天所要讨论的知识发现。 * * * * * * * * * * * * * 了解被引用情况，引用文献是在此工作基础上的发展与延续…… 检索结果全记录页面 查找该文章相关记录 浏览相关记录，无需增加任何检索词，获得相关文献 可浏览共被引的参考文献 浏览共被引的参考文献 创建引文跟踪服务 点击创建引文跟踪服务 保存到管理软件
