In fact, anyone working in Software Engineering is confronted with the task of understanding programs, at one level or another, in one form or another, and normally s/he succeeds rather well. However, we don't have any clear understanding of what ?to understand programs? means: is it to extract the program's structure or control/data flows? Is it to understand the relations between data and its transformations with respect to meanings in the application domain? Etc. We do neither have explicit guidelines to help us to perform a given program understanding task, nor do we have good criteria to decide how to represent knowledge derived by and used for program understanding. We conclude from the latter a strong need for further (fundamental) research in the Program Understanding area itself.Below is a provisional list of questions about program understanding: How could we define ?Program Understanding?? When do we decide we understand (enough) a program? What kind of program understanding do we achieve depending on the task at hand? How do we represent, in our minds, on paper or in files, our understanding of a program? What kind of help can we get from existing Program Understanding tools? What would we like to get actually (be it feasible or not)? What can we expect to have, as automatic help to understand programs, in the near future, in the long term? How could we describe our experiments, our own knowledge, so that they can be shared, re-used? What about Program Understanding Patterns?The goal of this Working Session is to exchange views on the former questions and others, to discuss possible research strategies, and to create an international interest group on Program Understanding, enhancing the sharing of tools, ideas and repositories.","PeriodicalId":448149,"journal":{"name":"Proceedings IWPC 2000. 8th International Workshop on Program Comprehension","volume":"213 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115509910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developers who are interested in the construction of robust, extensible software that is easy to maintain should expect to deploy a range of these techniques, as appropriate to the task. In this paper, we provide a foundation for the application of established software metrics to the measurement of context-free grammars. The usual application of software metrics is to program code; we provide a mapping that allows these metrics to be applied to grammars. This allows us to interpret six software engineering metrics in a grammatical context, including T.J. McCabe's (1976) complexity metric and N.E. Fenton et al.'s (1996) impurity metric. We have designed and implemented a tool to automatically compute the six metrics; as a case study, we use these six metrics to measure some of the properties of grammars for the Oberon, ISO C, ISO C++ and Java programming languages. We believe that the techniques that we have developed can be applied to estimating the difficulty of designing, implementing, testing and maintaining parsers for large grammars.","PeriodicalId":448149,"journal":{"name":"Proceedings IWPC 2000. 8th International Workshop on Program Comprehension","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123613278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This simplification power can be used to answer questions a software engineer might have about a program by first augmenting the program to make the question explicit and then slicing out an answer. One benefit of this technique is that the answer is in the form of a program and thus, in a language that the software engineer understands well. To test the usefulness of amorphous slicing in answering such questions, the question of array access safety is considered. A safety slice (an amorphous slice of an augmented program) is used to guide a software engineer to potential array bounds violations. A series of experiments was conducted to determine whether the safety slice was an effective aid to an engineer. 76 subjects participated in the controlled experiments. For experiments involving novice programmers, the null hypothesis could not be rejected, and so it was not possible to conclude that amorphous slicing assisted such programmers. However for more experienced groups, the experimental subjects (who were able to consult amorphous slices) significantly outperformed the control group. The study lends empirical support to the assertion that amorphous slicing assists program comprehension.","PeriodicalId":448149,"journal":{"name":"Proceedings IWPC 2000. 8th International Workshop on Program Comprehension","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122196905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
