嵌入Twitter的超链接，作为国际大学网站外部链接总数的代理
Hyperlinks embedded in Twitter as a proxy for total external inlinks to international university websites
摘要：
本文分析了Twitter作为一个潜在的替代来源的外部链接用于网络计量分析，因为它的能力，嵌入超链接在不同的推文。考虑到搜索Twitter公共API的局限性，我们决定使用Topsy搜索引擎作为编译tweet的源。为此，我们在全球范围内抽取了200所大学的样本，并收集了所有与这些机构有超链接的推文。为了比较结果，从其他来源（MajesticSEO和OpenSiteExplorer）获得了更多的链接数据。此后，进行了各种统计测试，以确定指标之间的相关性和从收集的推文预测外部链接的能力。结果表明，推文数量很高，尽管它们受到特定大学和国家的存在和表现的影响。Topsy提供的数据与所有链接指标显着相关，特别是与OpenSiteExplorer（r=0.769）。最后，由于高出错率，预测模型不能提供最佳结果，在应用于特定环境的非线性模型中，这种高出错率略有下降。我们的结论是，使用Twitter（通过Topsy）作为超链接到大学的来源产生了可喜的成果，由于其高度的相关性与链接指标，但有限的政策和文化的使用和存在于社交网络。
英文摘要：
This article analyzes Twitter as a potential alternative source of external links for use in webometric analysis because of its capacity to embed hyperlinks in different tweets. Given the limitations on searching Twitter's public API, we decided to use the Topsy search engine as a source for compiling tweets. To this end, we took a global sample of 200 universities and compiled all the tweets with hyperlinks to any of these institutions. Further link data was obtained from alternative sources (MajesticSEO and OpenSiteExplorer) in order to compare the results. Thereafter, various statistical tests were performed to determine the correlation between the indicators and the ability to predict external links from the collected tweets. The results indicate a high volume of tweets, although they are skewed by the presence and performance of specific universities and countries. The data provided by Topsy correlated significantly with all link indicators, particularly with OpenSiteExplorer (r=0.769). Finally, prediction models do not provide optimum results because of high error rates, which fall slightly in nonlinear models applied to specific environments. We conclude that the use of Twitter (via Topsy) as a source of hyperlinks to universities produces promising results due to its high correlation with link indicators, though limited by policies and culture regarding use and presence in social networks.
