在本文中，我们采取了IPL 2和Yahoo！答案作为我们的数字参考和基于社区的问答网站的案例研究的两个样本。我们检查了这两个系统的服务的基础上提出的200个真实的问题在IPL 2和他们的类似问题发现在雅虎！答案比较了两个平台中相似问题的问题类型、主题分类、回答类型和回答时延。结果分析表明，两个系统对问题的分类不同，所提问题的类型也不同。从IPL 2获得答案需要更长的时间，而Yahoo！答案产生了截然不同的响应时间。然而，一些差异也表明，有必要考虑将两个系统中的某些想法结合起来。
In this paper, we took IPL2 and Yahoo! Answers as the two samples for our case study of digital references and community-based Q&A sites. We examined the services of the two systems based on 200 real questions raised in IPL2 and their similar questions found in Yahoo! Answers. Question type, topic classification, answer type, and answer time delay were compared between the similar questions in these two platforms. The result analysis showed that the two systems classify their questions differently, and the types of the questions asked are different too. It took much longer time to obtain answers from IPL2, whereas different types of questions in Yahoo! Answers generated dramatically different response time. However, some differences also demonstrated that there is need to consider integrating certain ideas in the two systems.
