堆栈溢出中重复共享外部链接的探讨
An Exploratory Study on the Repeatedly Shared External Links on Stack Overflow
摘要：
在Stack Overflow上，用户重复使用11，926，354个外部链接来共享Stack Overflow网站外部托管的资源。外部链接连接到现有的编程相关知识，并扩展了Stack Overflow上的众包知识。有些外部链接，即所谓的重复外部链接，可以多次共享。我们观察到，82.5%的链接共享活动（即，在Stack Overflow上的任何问题、答案或评论中共享链接）共享外部资源，并且57.0%的外部链接的出现是共享重复的外部链接。但是，目前还不清楚哪些类型的外部资源被重复共享。为了帮助用户管理他们的知识，我们希望研究Stack Overflow上知识共享中重复外部链接的特征。在本文中，我们分析了堆栈溢出上的重复外部链接。我们观察到，指向文本资源（托管在文档网站，教程网站等）的外部链接被重复分享的次数最多。我们注意到：1）不同的用户以重复的外部链接的形式重复共享相同的知识，从而增加了知识的维护工作量（例如，更新多个帖子中的无效链接），2）相同的用户可以出于推广的目的重复地共享外部链接，以及3）外部链接可以指向具有用户难以检索相关信息的信息过载的网页。我们的研究结果为Stack Overflow的主持人和研究人员提供了见解。例如，我们鼓励Stack Overflow集中管理重复外部链接形式的常见知识，以更好地维护Stack Overflow上的众包知识。
英文摘要：
On Stack Overflow, users reuse 11,926,354 external links to share the resources hosted outside the Stack Overflow website. The external links connect to the existing programming-related knowledge and extend the crowdsourced knowledge on Stack Overflow. Some of the external links, so-called as repeated external links, can be shared for multiple times. We observe that 82.5% of the link sharing activities (i.e., sharing links in any question, answer, or comment) on Stack Overflow share external resources, and 57.0% of the occurrences of the external links are sharing the repeated external links. However, it is still unclear what types of external resources are repeatedly shared. To help users manage their knowledge, we wish to investigate the characteristics of the repeated external links in knowledge sharing on Stack Overflow. In this paper, we analyze the repeated external links on Stack Overflow. We observe that external links that point to the text resources (hosted in documentation websites, tutorial websites, etc.) are repeatedly shared the most. We observe that: 1) different users repeatedly share the same knowledge in the form of repeated external links, thus increasing the maintenance effort of knowledge (e.g., update invalid links in multiple posts), 2) the same users can repeatedly share the external links for the purpose of promotion, and 3) external links can point to webpages with an overload of information that is difficult for users to retrieve relevant information. Our findings provide insights to Stack Overflow moderators and researchers. For example, we encourage Stack Overflow to centrally manage the commonly occurring knowledge in the form of repeated external links in order to better maintain the crowdsourced knowledge on Stack Overflow.
