维基百科作为网络门户的价值
On the Value of Wikipedia as a Gateway to the Web
摘要：
通过链接到外部网站，维基百科可以作为一个门户网站。然而，迄今为止，人们对维基百科外部链接产生的流量知之甚少。我们通过详细分析从维基百科用户的客户端设备收集的使用日志来填补这一空白。我们的分析分为三个步骤：首先，我们量化了外部链接的参与程度，发现在一个月内，英文维基百科产生了4300万次外部网站的点击，其中通过信息框，引用参考文献和文章正文中的链接的点击量大致相等。信息框中列出的官方链接的点击率（CTR）最高，平均为2.47%。特别是，与商业、教育机构和网站相关的官方链接具有最高的CTR，而与地理内容、电视和音乐相关的官方链接具有最低的CTR。其次，我们调查了外部链接的参与模式，发现维基百科经常作为搜索引擎和第三方网站之间的垫脚石，有效地满足了搜索引擎无法满足的信息需求。第三，我们量化了外部网站从英文维基百科获得的点击的假设经济价值，估计各个网站的所有者每月需要支付700 - 1300万美元才能获得相同数量的流量通过赞助搜索。总的来说，这些发现揭示了维基百科不仅是一个重要的信息来源，而且是一个通往更广泛的网络生态系统的高流量门户。
英文摘要：
By linking to external websites, Wikipedia can act as a gateway to the Web. To date, however, little is known about the amount of traffic generated by Wikipedia's external links. We fill this gap in a detailed analysis of usage logs gathered from Wikipedia users' client devices. Our analysis proceeds in three steps: First, we quantify the level of engagement with external links, finding that, in one month, English Wikipedia generated 43M clicks to external websites, in roughly even parts via links in infoboxes, cited references, and article bodies. Official links listed in infoboxes have by far the highest click-through rate (CTR), 2.47% on average. In particular, official links associated with articles about businesses, educational institutions, and websites have the highest CTR, whereas official links associated with articles about geographical content, television, and music have the lowest CTR. Second, we investigate patterns of engagement with external links, finding that Wikipedia frequently serves as a stepping stone between search engines and third-party websites, effectively fulfilling information needs that search engines do not meet. Third, we quantify the hypothetical economic value of the clicks received by external websites from English Wikipedia, by estimating that the respective website owners would need to pay a total of $7--13 million per month to obtain the same volume of traffic via sponsored search. Overall, these findings shed light on Wikipedia's role not only as an important source of information, but also as a high-traffic gateway to the broader Web ecosystem.
