Program comprehension is an important activity in software maintenance, as software must be sufficiently understood before it can be properly modified. The study of a program's execution, known as dynamic analysis, has become a common technique in this respect and has received substantial attention from the research community, particularly over the last decade. These efforts have resulted in a large...
Gaining an understanding of software systems is an important discipline in many software engineering contexts. It is essential that sofiware engineers are assisted as much as possible during this task, e.g., by using tools and techniques that provide architectural views on the software at hand. This Ph.D. research addresses this issue by employing dynamic analysis for the reconstruction of such views...
The following topics are dealt with: program comprehension; software engineering; formal concept analysis; object-oriented reverse engineering; UML; software repository mining; dynamic program analysis; conceptual model; static program analysis and program visualization.
Over the past fifteen years, the software reverse engineering community has produced many software engineering methods, tools, and techniques that have had significant impact in the software industry. After a research area has evolved for 10-20 years, it can easily fade away due to narrow focus, overgrazing, or lack of impact. Trying to assess the impact of various approaches and results in a research...
Dynamic analysis has long been a subject of study in the context of (compiler) optimization, program comprehension, test coverage, etc. Ever-since, the scale of the event trace has been an important issue. This scalability issue finds its limits on the computational front, where time and/or space complexity of algorithms become too large to be handled by a computer, but also on the cognitive front,...
During initial program comprehension, software engineers could benefit from knowing the most need-to-be-understood classes in the system under study in order to kick-start their software reconnaissance. Previously we have used Webmining techniques on runtime trace data to identify these important classes. Here, we reprise this Webmining technique and make a thorough comparison of its effectiveness...
