虽然在学术文献中对引文的分析现在已经是信息科学的一个既定的和相对容易理解的部分，但是对于可以在网络上找到的引文的了解还不够。特别是，是否有新的网络类型，如果有，这些是琐碎的还是潜在的有用的研究或评估研究交流？我们从64种开放获取期刊（包括生物学、物理学、化学和计算机）的1577个网址或研究文章标题的网络引用样本中寻找证据。只有25%代表智力影响，来自网络文档参考（23%）和其他非正式学术来源（2%）。许多Web/URL引用是为一般或特定主题导航（45%）或自我宣传（22%）而创建的。进一步的分析揭示了谷歌独特的Web/URL引用类型以及Web上科学开放获取出版的一些特征的显著学科差异。我们的结论是，网络提供了一种新的、不同类型的引文信息，因此可以使我们衡量研究的不同方面，特别是研究过程；但是为了获得好的信息，应该将不同的类型分开。
Although the analysis of citations in the scholarly literature is now an established and relatively well understood part of information science, not enough is known about citations that can be found on the Web. In particular, are there new Web types, and if so, are these trivial or potentially useful for studying or evaluating research communication? We sought evidence based upon a sample of 1,577 Web citations of the URLs or titles of research articles in 64 open-access journals from biology, physics, chemistry, and computing. Only 25% represented intellectual impact, from references of Web documents (23%) and other informal scholarly sources (2%). Many of the Web/URL citations were created for general or subject-specific navigation (45%) or for self-publicity (22%). Additional analyses revealed significant disciplinary differences in the types of Google unique Web/URL citations as well as some characteristics of scientific open-access publishing on the Web. We conclude that the Web provides access to a new and different type of citation information, one that may therefore enable us to measure different aspects of research, and the research process in particular; but to obtain good information, the different types should be separated.
