先前的研究表明，来自不同类型的Web源的引文数据可以用于研究评估。在这里，我们介绍一个新的综合在线影响（IOI）指标。作为案例研究，我们选择了2003年发表在《美国信息科学与技术学会杂志》（JASIST）和《科学计量学》上的研究文章。我们比较了Web of Science（WoS）和Scopus的引文计数与五个在线引文数据来源，包括Google Scholar，Google Books，Google Blogs，PowerPoint演示文稿和课程阅读列表。IOI的平均值和中位数几乎是WoS和Scopus的两倍，这证实了在线引文数量足够多，可以用于研究的影响评估。我们还发现传统和在线影响力指标之间存在显著相关性，证实两者在学术交流中评估相似的东西。进一步的分析显示，在WoS之外的唯一Google Scholar引用的总体百分比分别为73%和60%，发表在JASIST和Scientometrics上的文章。一个重要的结论是，在研究评估需要WoS和Scopus数据库之外的更广泛类型的智力影响指标的学科领域，IOI可以用来帮助监测研究绩效。(C)2009爱思唯尔有限公司保留所有权利。
Previous research has shown that citation data from different types of Web sources can potentially be used for research evaluation. Here we introduce a new combined Integrated Online Impact (IOI) indicator. For a case study, we selected research articles published in the Journal of the American Society for Information Science & Technology (JASIST) and Scientometrics in 2003. We compared the citation counts from Web of Science (WoS) and Scopus with five online sources of citation data including Google Scholar, Google Books, Google Blogs, PowerPoint presentations and course reading lists. The mean and median IOI was nearly twice as high as both WoS and Scopus, confirming that online citations are sufficiently numerous to be useful for the impact assessment of research. Wealso found significant correlations between conventional and online impact indicators, confirming that both assess something similar in scholarly communication. Further analysis showed that the overall percentage for unique Google Scholar citations outside the WoS were 73% and 60% for the articles published in JASIST and Scientometrics, respectively. An important conclusion is that in subject areas where wider types of intellectual impact indicators outside the WoS and Scopus databases are needed for research evaluation, IOI can be used to help monitor research performance.
