点科学顶级域名：学术网站还是垃圾网站？
Dot-Science Top Level Domain: academic websites or dumpsites?
摘要：
Dot-science于2015年推出，是一个新的学术顶级域名，旨在为“对科学感兴趣的全球互联网用户提供一个专用的，易于访问的位置”。这项工作的主要目标是找出这个顶级域的一般学术用法。具体而言，调查了以下三个问题：使用情况（在dot-science注册的网站域名数量）、目的（与这些网站域名链接的网站的主要功能和类别）和影响（网站的知名度和权威性）。为此，通过ICANN的域名注册数据库收集了13，900个域名。随后对每个Web域进行了分类，并从Majestic的API中获得了有关Web影响的数据。根据所获得的结果，可以得出结论，.科学顶级域名几乎没有被学术界采用，主要被注册公司用于转售目的（所有Web域名的35.5%被停放）。反向链接数量最多的网站通常与非学术网站有关，这些网站采用了密集的链接建设做法，并提供休闲甚至欺诈内容。Majestic的信任流度量方法已被证明是一种有效的学术网站过滤方法。至于与学术相关的主要网络科学领域类别，发现了1，175个（占所有注册域名的8.5%），主要是个人学术网站（342个域名），博客（261个）和研究小组（133个）。所有可疑的内容都揭示了网络上的不良做法，在网络上，“科学”标签从根本上被用作欺骗搜索引擎算法的机制。
英文摘要：
Dot-science was launched in 2015 as a new academic top-level domain (TLD) aimed to provide 'a dedicated, easily accessible location for global Internet users with an interest in science'. The main objective of this work is to find out the general scholarly usage of this top-level domain. In particular, the following three questions are pursued: usage (number of web domains registered with the dot-science), purpose (main function and category of websites linked to these web domains), and impact (websites' visibility and authority). To do this, 13,900 domain names were gathered through ICANN's Domain Name Registration Data Lookup database. Each web domain was subsequently categorized, and data on web impact were obtained from Majestic's API. Based on the results obtained, it is concluded that the dot-science top-level domain is scarcely adopted by the academic community, and mainly used by registrar companies for reselling purposes (35.5% of all web domains were parked). Websites receiving the highest number of backlinks were generally related to non-academic websites applying intensive link building practices and offering leisure or even fraudulent contents. Majestic's Trust Flow metric has been proved an effective method to filter reputable academic websites. As regards primary academic-related dot-science web domain categories, 1,175 (8.5% of all web domains registered) were found, mainly personal academic websites (342 web domains), blogs (261) and research groups (133). All dubious content reveals bad practices on the Web, where the tag 'science' is fundamentally used as a mechanism to deceive search engine algorithms.
