Empirical Evidence of Large-Scale Diversity in API Usage of Object-Oriented Software
In this paper, we study how object-oriented classes are used across thousands
of software packages. We concentrate on "usage diversity'", defined as the
different statically observable combinations of methods called on the same
object. We present empirical evidence that there is a significant usage
diversity for many classes. For instance, we observe in our dataset that Java's
String is used in 2460 manners. We discuss the reasons of this observed
diversity and the consequences on software engineering knowledge and research
Automatic Software Repair: a Bibliography
This article presents a survey on automatic software repair. Automatic
software repair consists of automatically finding a solution to software bugs
without human intervention. This article considers all kinds of repairs. First,
it discusses behavioral repair where test suites, contracts, models, and
crashing inputs are taken as oracle. Second, it discusses state repair, also
known as runtime repair or runtime recovery, with techniques such as checkpoint
and restart, reconfiguration, and invariant restoration. The uniqueness of this
article is that it spans the research communities that contribute to this body
of knowledge: software engineering, dependability, operating systems,
programming languages, and security. It provides a novel and structured
overview of the diversity of bug oracles and repair operators used in the
literature
Hidden Populations in Software Engineering: Challenges, Lessons Learned, and Opportunities
The growing emphasis on studying equity, diversity, and inclusion within
software engineering has amplified the need to explore hidden populations
within this field. Exploring hidden populations becomes important to obtain
invaluable insights into the experiences, challenges, and perspectives of
underrepresented groups in software engineering and, therefore, devise
strategies to make the software industry more diverse. However, studying these
hidden populations presents multifaceted challenges, including the complexities
associated with identifying and engaging participants due to their marginalized
status. In this paper, we discuss our experiences and lessons learned while
conducting multiple studies involving hidden populations in software
engineering. We emphasize the importance of recognizing and addressing these
challenges within the software engineering research community to foster a more
inclusive and comprehensive understanding of diverse populations of software
professionals
Social Computing for Software Engineering: a Mapping Study.
There is a continual growth in the use of social computing within a breadth of business domains; such as marketing, public engagement and innovation management. Software engineering research, like other similar disciplines, has re- cently started to harness the power of social computing throughout the various development phases; from requirements elicitation to validation and maintenance and for the various methods of development and structures of development teams. However, despite this increasing effort, we still lack a clear picture of the current status of this research. To address that lack of knowledge, we conduct a systematic mapping study on the utilisation of social computing for software engineering. This will inform researchers and practitioners about the current status and progress of the field including the areas of current focus and the geographical and chronological distribution of the research. We do the mapping across a diversity of dimensions including the activities of software engineering, the types of research, the characteristics of social computing and the demographic attributes of the published work. Our study results show a growing interest in the field, mainly in academia, and a general trend toward developing designated social com- puting platforms and utilising them in mainly four software engineering areas; management, coding, requirements engineering, and maintenance and enhancement
Validity concerns in software engineering research
Empirical studies that use software repository artifacts have become popular in the last decade due to the ready avail-ability of open source project archives. In this paper, we survey empirical studies in the last three years of ICSE and FSE proceedings, and categorize these studies in terms of open source projects vs. proprietary source projects and the diversity of subject programs used in these studies. Our survey has shown that almost half (49%) of recent empirical studies used solely open source projects. Existing studies either draw general conclusions from these results or explic-itly disclaim any conclusions that can extend beyond specific subject software. We conclude that researchers in empirical software engi-neering must consider the external validity concerns that arise from using only several well-known open source soft-ware projects, and that discussion of data source selection is an important discussion topic in software engineering re-search. Furthermore, we propose a community research in-frastructure for software repository benchmarks and sharing the empirical analysis results, in order to address external validity concerns and to raise the bar for empirical software engineering research that analyzes software artifacts
