大数据驱动的开发者社区中知识交流网络的分析

Big Data Driven Analysis of Knowledge Exchange Network in Developer Community

开发者社区一般包括博客、问答和论坛等多个版块,这些版块共同构成了用户贡献和交流软件开发知识的平台。文中以CSDN为研究对象,通过分析CSDN平台上积累的大数据构建了开发者知识交流网络,并基于复杂网络理论对其进行了分析,发现多版块的知识交流网络具有小世界、无标度等复杂网络特性。基于知识交流网络进一步分析了知识贡献者的分布情况,发现多版块用户中有较多的知识贡献者,其在知识交流网中起着比较重要的作用。

Developer community generally has various sections such as blog,QA,bbs,etc.These sections together constitute a platform where users contribute and communicate software development knowledge.This paper concentrated and analyzed the big data accumulated in CSDN and constructed knowledge exchange networks.Analysis of the networks based on complex network method indicates the small-world effect and scale-free property of multi-section knowledge exchange network.Further study shows that there exist relatively more knowledge distributors in multi-section users and they play a relative more important role in the knowledge exchange network.
