| 1 | What Security Questions Do Developers Ask? A Large-Scale Study of Stack Overflow Posts显示文摘安全总是是一个流行、批评的话题。与信息技术的快速的发展,它总是正在吸引民族注意。然而,自从安全有长历史,它论及改变很多的大量话题,从经典密码学到最近流行活动安全。有需要调查安全相关的话题和趋势,它能是为安全研究人员,安全教育者和安全专业人员的一个指南。到地址上述在这篇论文,我们需要在栈溢出上在安全相关的问题上进行大规模研究。栈溢出是一个流行联机问题和答案地点让软件开发者传达,协作,并且分享与对方一起的信息。在在栈溢出上张贴的众多的问题之中有许多不同话题,安全相关的问题占据一个大比例并且有一个重要、重要的位置。我们首先使用二条启发规则从数据集提取基于帖子的标签与安全有关的问题。然后我们使用一个先进话题模型,潜伏的 Dirichlet 分配(LDA ) 调节了使用基因算法(GA ) ,基于他们的文章聚类不同安全相关的问题。在获得安全相关的问题的不同话题以后,我们使用他们的元数据做各种各样的分析。我们总结所有话题进五个主要范畴,并且也调查不同话题的流行和困难。基于我们的学习的结果,我们为研究人员,教育者和专业人员结束几个含意。 | Xin-Li Yang David Lo Xin Xia Zhi-Yuan Wan Jian-Ling Sun | 2016 | Journal of Computer Science & Technology2016，31，5： | 8 |
| 2 | Mining Design Pattern Use Scenarios and Related Design Pattern Pairs:A Case Study on Online Posts显示文摘In common design pattern collections,e.g.,design pattern books,design patterns are documented with templates that consist of multiple attributes,such as intent,structure,and sample code.To adapt to modern developers,the depictions of design patterns,especially some specific attributes,should advance with the current programming technologies,for example,“known uses”,which exemplifies the use scenarios of design patterns in practice,and“related patterns”,which describes the relatedness between a design pattern and the others within a context.However,it is not easy to update the contents of these attributes manually due to the diversity of the programming technologies.To address this problem,in this work,we conducted a case study to mine design pattern use scenarios and related design pattern pairs from Stack Overflow posts to enrich the two attributes.We first extracted the question posts relevant to each design pattern by identifying the design pattern tags.Then,the topics of the posts were discovered by applying topic modeling techniques.Finally,by analyzing the topics specified for each design pattern,we detected 195 design pattern use scenarios and 70 related design pattern pairs,involving 61 design patterns totally.These findings are associated with a variety of popular software frameworks and programming techniques.They could complement the existing design pattern collections and help developers better acknowledge the usage and relatedness of design patterns in today's programming practice. | Dong Liu Zhi-Lei Ren Zhong-Tian Long Guo-Jun Gao He Jiang | 2020 | Journal of Computer Science & Technology2020，35，5： | 1 |
