ABSTRACT
While question answering communities have been gaining
popularity for several years, we wonder if the increased popularity
actually improves or degrades the user experience. In addition,
automatic QA systems, which utilize different sources such as
search engines and social media, are emerging rapidly. QA
communities have already created abundant resources of millions
of questions and hundreds of millions of answers. The question
whether they will continue to serve as an effective source of
information for web search and question answering is of vital
importance. In this poster, we investigate the temporal evolution
of a popular QA community ­Yahoo! Answers, with respect to its
effectiveness in answering three basic types of questions: factoid,
opinion and complex questions. Our experiments show that
Yahoo! Answers keeps growing rapidly, while its overall quality
as an information source for factoid question-answering degrades.
