社会化问答平台中问题属性对答案域的影响

Questions Attributes' Impact on Answer Domains in a Social Q & A Platform

社会化问答平台中,问题的主客观属性会影响用户的回答。本文采集了Yahoo!Answers中的2604个问答对,对问题属性与答案域属性进行相关性分析,研究发现:问题的字数多少、包含细节信息的多少与答案的数量没有正相关关系;问题中的句子平均长度越短、问题的可读性越强,越有可能吸引更多的回答者,获得的答案也更详尽;而在问题中使用感谢、急迫等带有情感表达的词汇,对获取更多、更详细的答案没有直接帮助。因此,问者在表述问题时应尽量使用言简意赅的短句子,并且尽量使用who,what,when,where,why,how等词来引导问题,增强问题可读性。

In a social Q ＆ A platform, subjective and objective questions will lead to different answers by the users. In this paper, 2604 pairs of questions and answers from the Yahool Answers were analyzed. It found out that numbers of words of questions and how detailed the information is had no positive correlation with the numbers of answers based on correlation analysis of questions attributes and answer domain. Conversely, the shorter the average length of questioning sentences is and the stronger readability of the questions is, the more attractive they become and the more detailed the answers tend to be. However, the usage of emotion expressions such as thanks or anxiety fails to attract more detailed answers. Thereby, this paper suggests the questioner use concise and short sentences to express the problems as much as possible, and try to use such words as ＂who＂, ＂what＂, ＂when＂, ＂where＂, ＂why＂ and ＂hew＂ to lead the questions so as to strengthen their readability.
