Item Metadata only Answering questions about unanswered questions of stack overflow(IEEE, 2013) Asaduzzaman, Muhammad; Mashiyat, Ahmed Shah; Roy, Chanchal K.; Schneider, Kevin A.Community-based question answering services accumulate large volumes of knowledge through the voluntary services of people across the globe. Stack Overflow is an example of such a service that targets developers and software engineers. In general, questions in Stack Overflow are answered in a very short time. However, we found that the number of unanswered questions has increased significantly in the past two years. Understanding why questions remain unanswered can help information seekers improve the quality of their questions, increase their chances of getting answers, and better decide when to use Stack Overflow services. In this paper, we mine data on unanswered questions from Stack Overflow. We then conduct a qualitative study to categorize unanswered questions, which reveals characteristics that would be difficult to find otherwise. Finally, we conduct an experiment to determine whether we can predict how long a question will remain unanswered in Stack Overflow.Item Metadata only VisCad: Flexible Code Clone Analysis Support for NiCad(ACM, 2011) Asaduzzaman, Muhammad; Roy, Chanchal K.; Schneider, Kevin A.Clone detector results can be better understood with tools that support visualization and facilitate in-depth analysis. In this tool demo paper we present VisCad, a comprehensive code clone analysis and visualization tool that provides such support for the near-miss hybrid clone detection tool, NiCad. Through carefully selectedmetrics and visualization techniques VisCad can guide users to explore the cloning of a system from different perspectives.
