A workflow describes how tasks are executed and ordered following business policies. E-commerce systems implement the workflows of the daily operations of an organization. Organizations must continuously modify their e-commerce systems in order to accommodate workflow changes. However, e-commerce systems are often designed and developed without referring to the workflows. Modifying e-commerce systems is a time consuming and error prone task. In order to correctly perform this task, developers require an in-depth understanding of multi tiered e-commerce systems and the workflows that they implement. In this paper, we present an approach which automatically recovers workflows from three tier e-commerce systems. Given the starting UI page of a particular workflow, the approach traces the flow of control throughout the different tiers of the e-commerce system in order to recover that workflow. We demonstrate the effectiveness of our approach through experiments on an open source e-commerce system.","PeriodicalId":135871,"journal":{"name":"15th IEEE International Conference on Program Comprehension (ICPC '07)","volume":"51 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123702920","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}

Such modules could lead to faults, and as such, may be in need of mitigating actions such as refactoring or more exhaustive testing. Source code metrics can be used as input features for a classifier, however, there exist a large number of measures that capture different aspects of coupling, cohesion, inheritance, complexity and size. In a large dimensional feature space some of the metrics may be irrelevant or redundant. Feature selection is the process of identifying a subset of the attributes that improves a classifier's discriminatory performance. This paper presents initial results of a genetic algorithm as a feature subset selection method that enhances a classifier's ability to discover cognitively complex classes that degrade program understanding.","PeriodicalId":135871,"journal":{"name":"15th IEEE International Conference on Program Comprehension (ICPC '07)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125265244","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}

For correct use of the provided API, proper documentation is needed. API usage is often demonstrated by giving example applications and code samples. In this paper we propose an approach for mining such usage scenarios from run-time communication between sample applications and the API. This is done automatically by first monitoring the API usage of sample applications, then filtering the generated traces, and finally synthesizing the sequence diagrams and illustrating them in a well-formed way as UML2 sequence diagrams. Such usage scenarios support the software engineer in comprehending the usage of the API. With proper tool support they can also be used for validating other applications' API usage and for generating code for a new application using the same API.","PeriodicalId":135871,"journal":{"name":"15th IEEE International Conference on Program Comprehension (ICPC '07)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129252344","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}

In this context software visualization is a widely used approach, since well-conceived visual representations allow one to spot patterns. The large majority of visualizations use 2D representations, because they are easier to construct, navigate, and interact with. 3D representations usually exploit the 3rd dimension as an additional means to encode quantitative values, which is dismissed by many as a too small benefit in the light of the added complexity in terms of navigation and interaction. We argue that a well-constructed, interactive, and easily navigable 3D visualization can greatly help in program comprehension tasks by supporting habitability. Habitability transmits to a developer the notion that a software system is a physical space with strong orientation points. This can give developers the feeling of being \"at home\" in a system. We propose a 3D visualization of software systems hinging on the city metaphor. It is useful for program comprehension because it leads to clarity about the overall structure of a system. We apply our visualization technique on two large systems and discuss its benefits and drawbacks.","PeriodicalId":135871,"journal":{"name":"15th IEEE International Conference on Program Comprehension (ICPC '07)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130158842","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}

Decompilers translate low-level class files to Java source and can produce \"good\" output. Obfuscators transform class files into semantically-equivalent versions that are either: (1) difficult to decompile, or (2) decompilable, but result in \"hard- to-understand\" Java source. We present a set of metrics developed to quantify the effectiveness of decompilers and obfuscators. The metrics include some selective size and counting metrics and an expression complexity metric. We have applied these metrics to evaluate a collection of decompilers and obfuscators. By quantitatively comparing original Java source against decompiled and obfuscated code respectively, we show which decompilers produce \"good\" code and whether obfuscations result in \"hard-to-understand\" code.","PeriodicalId":135871,"journal":{"name":"15th IEEE International Conference on Program Comprehension (ICPC '07)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128865767","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}

Iyer","doi":"10.1109/ICPC.2007.43","DOIUrl":"https://doi.org/10.1109/ICPC.2007.43","url":null,"abstract":"Regulatory agencies, such as US FDA, and other third party reviewers of software have the task of comprehending apiece of software in the event of its failure. Program slicing is the preferred technique to analyze software failures. However, program slicing might yield extremely large slices and also demand that an user have intimate knowledge of the software (by specifying a slicing criterion). In this paper we propose solutions to ameliorate both of these problems. The main hypothesis of the paper is that error reports can be used to generate slicing criteria, thus allowing a third-party reviewer to use slicing without any knowledge of the system being analyzed. The first contribution of the paper is a study of how error reports can be formalized and how execution sequences (called error traces) that satisfy an error report can be identified, which can then be sliced. A primary feature of this work is that incomplete error reports could be dealt with. The second contribution of the paper is a scheme for using abstract interpretation in the generation of error traces and (potential) slicing criteria from error reports. These \"abstract\" error traces can be sliced, much like in dynamic/conditional slicing, with respect to the criteria generated, allowing for inputs to be used to reduce the size of slices. Furthermore, being abstract in nature, they are shorter than exact execution sequences and also allow for easier comprehension. We finally present a case study involving a medical device that illustrates how our approach can aid with program comprehension.","PeriodicalId":135871,"journal":{"name":"15th IEEE International Conference on Program Comprehension (ICPC '07)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128901375","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}

A variety of tools have been created to improve the effectiveness of such exploration. The usefulness of these tools has been argued largely on the basis of case studies, small narrowly-focussed experiments, or non-human-based experiments. In this paper, we report on a more rigorously controlled study of three specialized software exploration tools in which professional programmers used the tools to plan complex change tasks to a medium-sized code base. We found that the tools had little apparent effect; the effects observed instead appear to be dominated by individual styles and strategies of the programmers and characteristics of the tasks. In addition to presenting the results of the study, this paper introduces the use of two experimental evaluation aids: the NASA task load index (TLX) for assessing task difficulty and distance profiles for assessing the to which programmers remain on-track.","PeriodicalId":135871,"journal":{"name":"15th IEEE International Conference on Program Comprehension (ICPC '07)","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124521360","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}
