We know surprisingly little about how professional developers define debugging and the challenges they face in industrial environments. To begin exploring professional debugging challenges and needs, we conducted and analyzed interviews with 15 professiona...
The Impact of Classifier Configuration and Classifier Combination on Bug Localization
Found in: IEEE Transactions on Software Engineering
By Stephen W. Thomas,Meiyappan Nagappan,Dorothea Blostein,Ahmed E. Hassan
Issue Date:October 2013

Load tests ensure that software systems are able to perform under the expected workloads. The current state of load test analysis requires significant manual review of performance counters and execution logs, and a high degree of system-specific expertise....
Predicting Bugs Using Antipatterns
Found in: 2013 IEEE International Conference on Software Maintenance (ICSM)
By Seyyed Ehsan Salamati Taba,Foutse Khomh, Ying Zou,Ahmed E. Hassan,Meiyappan Nagappan
Issue Date:September 2013
pp. 270-279
Bug prediction models are often used to help allocate software quality assurance efforts. Software metrics (e.g., process metrics and product metrics) are at the heart of bug prediction models. However, some of these metrics like churn are not actionable, ...
An empirical study of build system migrations in practice: Case studies on KDE and the Linux kernel
Found in: 2012 IEEE International Conference on Software Maintenance (ICSM)
By Roman Suvorov,Meiyappan Nagappan,Ahmed E. Hassan,Ying Zou,Bram Adams
Issue Date:September 2012
pp. 160-169
As the build system, i.e. the infrastructure that constructs executable deliverables out of source code and other resources, tries to catch up with the ever-evolving source code base, its size and already significant complexity keep on growing. Recently, t...
Analysis of execution log files
Found in: Software Engineering, International Conference on
By Meiyappan Nagappan
Issue Date:May 2010
pp. 409-412
Log analysis can be used to find problems, define operational profiles, and even pro-actively prevent issues. The goal of my dissertation research is to investigate log management and analysis techniques suited for very large and very complex logs, such as...
Efficient Operational Profiling of Systems Using Suffix Arrays on Execution Logs
Found in: Software Reliability Engineering, International Symposium on
By Meiyappan Nagappan, Mladen A. Vouk, Kesheng Wu, Alex Sim, Arie Shoshani
Issue Date:November 2008
pp. 313-314
Operational profiles are an essential part of software reliability engineering. Typically they are created from the software requirements, and through customer reviews. Creation of operational profiles often is laborious and requires human intervention. Ou...
Replicating and Re-evaluating the Theory of Relative Defect-Proneness
Found in: IEEE Transactions on Software Engineering
By Mark Syer,Meiyappan Nagappan,Bram Adams,Ahmed Hassan
Issue Date:February 2015
pp. 1
A good understanding of the factors impacting defects in software systems is essential for software practitioners, because it helps them prioritize quality improvement efforts (e.g., testing and code reviews). Defect prediction models are typically built u...
On the Relationship between the Number of Ad Libraries in an Android App and its Rating
Found in: IEEE Software
By Israel Mojica Ruiz,Meiyappan Nagappan,Bram Adams,Thorsten Berger,Steffen Dienst,Ahmed Hassan
Issue Date:May 2014
pp. 1
One of the most popular ways to monetize a free app is by including advertisements in the app. There are several advertising (ad) companies that provide these ads to the app developers through ad libraries that need to be integrated in the app. However, th...
