摘要
[目的/意义]本文从知识特征的角度,对在线问答社区中问题质量和价值的影响因素进行分析,为优化用户生成内容质量、实现有效的知识共享提供参考。[方法/过程]以编程问答社区Stack Overflow为研究对象,收集社区建设以来10年的数据,从知识的大众化程度、知识间的关联程度、知识的多样化程度、知识在网络中的重要程度4个方面,考察哪些知识特征会影响社区用户对于问题质量的评价。[结果/结论]知识特征对问题的内容质量具有显著影响。其中,知识间的关联程度、知识在网络中的重要程度,对问题得到的评价具有正向影响作用;随着知识的大众化水平提高,问题得到的评价呈现先升后降的趋势。
[Purpose/Significance]The study explores why some questions are highly rated by emphasizing the knowledge characteristics embedded in the questions,so as to provide reference for optimizing the quality of user-generated content and realizing effective knowledge sharing.[Methods/Process]Data from a programming-related Q&A site—Stack Overflow for ten years were collected,spanning the years from 2008 to 2017.The influence of knowledge characteristics on question score was analyzed from four aspects:knowledge popularity,knowledge correlation,knowledge diversity and knowledge importance.[Results/Conclusions]The research found that knowledge characteristics had a significant impact on content quality.Questions with highly relevant tags and tags of high network importance were more likely to get high scores.The tag frequency was curvilinearly related to the likelihood of attention allocation to questions in an inverted U-shape,which showed that proper tag frequency helps to improve question evaluation.
