At this year’s “International Conference on Generative Programming: Concepts & Experiences (GPCE)”, Saarbr\u00fccken computer science professor Sven Apel and colleagues were presented with a “Most Influential Paper Award”. The award honors work that has had a lasting impact on their field of research. The winning paper was published back in 2013.<\/strong><\/p>\n

In their paper “Does the discipline of preprocessor annotations matter?: A controlled experiment.”, Sven Apel and his colleagues J\u00f6rg Liebig, Sandro Schulze, and Janet Siegmund investigated so-called program annotations – information attached to the code that programmers use to highlight certain functions or to incorporate alternative paths into the execution of a program. They differentiated between “disciplined” annotations, which are well integrated into the code, and “undisciplined” annotations, which are used rather arbitrarily. The aim of the research was to find out whether disciplined annotations facilitate understanding and error correction in the code.<\/p>\n

For this study, the research team used an experimental approach that was innovative in the research landscape on program comprehension at the time: they divided test subjects into two groups and had them work on tasks in a controlled environment that contained either disciplined or undisciplined annotations. Then the performance was measured in terms of correctness and response time. “Surprisingly, our results indicated that the type of annotations had no influence on comprehension. However, finding and correcting errors was more time-consuming when annotations were present in the code – regardless of whether they were disciplined or not,” explains Sven Apel.<\/p>\n

The computer scientist from Saarbr\u00fccken emphasizes that it was the experimental method that led to the award. Before their study, there was virtually no empirical data on this topic – people relied on experience and the assumption that “clean” code was easier to understand. “Our work was one of the first to apply interdisciplinary methods in program comprehension research in order to achieve solid empirical results. Today, the experimental setup is standard,” says the professor.<\/p>\n

Sven Apel and his colleagues continue to be very successful in researching the comprehension of program code. In addition to another “Most Influential Paper Award”, Sven Apel in 2022 received an ERC Advanced Grant which is endowed with a 2.5 million Euro for the project titled “Brains on Code: A Neuroscientific Foundation of Program Comprehension”.<\/p>\n
