In addition to structural rules, the software component may imply interaction rules that must be followed in application development. In this paper we discuss behavioral profiles, given in UML, used to capture and illustrate architecturally significant behavioral rules. The behavioral rules may capture interaction rules to be obeyed when reusing an existing software component. They can also be used to support runtime analysis of existing systems: with a proper tool support, the validity of extracted interaction models can be automatically checked against the behavioral rules given in the profiles. Moreover, the profiles can be used to prune the size of the interaction trace to include only the information relevant from the point of view of the behavioral rules. In this paper we discuss such tool support and demonstrate the usefulness of the approach by applying behavioral profiles to define and illustrate behavioral rules relevant for applications using the graphical editing framework (GEF). Moreover, we analyze a sample GEF application by validating its run-time behaviour with respect to the defined behavioral rules","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122796014","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}

The main contribution consists in the combination of two existing techniques for feature location in source code. Both techniques provide a set of ranked facts from the software, as result to the feature identification problem. One of the techniques is based on a scenario based probabilistic ranking of events observed while executing a program under given scenarios. The other technique is defined as an information retrieval task, based on the latent semantic indexing of the source code. We show the viability and effectiveness of the combined technique with two case studies. A first case study is a replication of feature identification in Mozilla, which allows us to directly compare the results with previously published data. The other case study is a bug location problem in Mozilla. The results show that the combined technique improves feature identification significantly with respect to each technique used independently","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122523313","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}

Mining the information stored in them has been shown to provide interesting insights into the history of the software development and evolution. Several different types of information have been extracted and analyzed from different points of view. However, these types of information have not been sufficiently cross-examined to understand how they might complement each other. In this paper, we present a systematic analysis of four aspects of the software repository of an open source project - source-code metrics, identifiers, return-on-investment estimates, and design differencing - to collect evidence about refactorings that may have happened during the project development. In the context of this case study, we comparatively examine how informative each piece of information is towards understanding the refactoring history of the project and how costly it is to obtain","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"244 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126824652","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}

Historically, static slicing techniques have been used for aiding post-mortem fault analysis. However, the slices obtained in this manner can often be too large and may not give a clear understanding of the code when dealing with complex reactive systems. We propose using model abstraction in conjunction with slicing to ameliorate the problem of understanding large slices. Combining slicing with abstraction provides the analyst with an integrated cognition model, leading to a better understanding of the code, and consequently more efficient error analysis. We formalize this concept through the notion of abstraction-driven slicing, and use it to develop CAdS, an automated tool to aid postmortem error detection in C programs using abstraction-driven static slicing. We list our experiences with CAdS and illustrate how it can be used to reduce effort involved in the postmortem analysis process","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127933552","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 paper discusses and debates approaches for addressing these issues. The paper's objective is twofold. First, is to explore the current state of the art in methods, tools and technologies that can assist in carrying out the required work and to identify a taxonomy of current approaches as well as, their strengths and weaknesses. The second objective is to identify open issues and research opportunities in the area of migrating legacy systems in Web enabled environments","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129443917","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}

Modifying clones is not always straight forward, because we might not know all the places that need modification. This is even more of a problem when several developers need to know about how to change the clones. In this paper, we correlate the code clones with the time of the modification and with the developer that performed the modification to detect patterns of how developers copy from one another. We develop visualization, named clone evolution view, to represent the evolution of the duplicated code. We show the relevance of our approach on several large case studies and we distill our experience in forms of interesting copy patterns","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125898608","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}

Similar to text summarization, where abstracts can be extracted from large documents, the aim of trace summarization is to take an execution trace as input and return a summary of its main content as output. The resulting summary can then be converted into a UML sequence diagram and used by software engineers to understand the main behavioural aspects of the system. Our approach to trace summarization is based on the removal of implementation details such as utilities from execution traces. To achieve our goal, we have developed a metric based on fan-in and fan-out to rank the system components according to whether they implement key system concepts or they are mere implementation details. We applied our approach to a trace generated from an object-oriented system called Weka that initially contains 97413 method calls. We succeeded to extract a summary from this trace that contains 453 calls. According to the developers of the Weka system, the resulting summary is an adequate high-level representation of the main interactions of the traced scenario","PeriodicalId":377450,"journal":{"name":"14th IEEE International Conference on Program Comprehension (ICPC'06)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128900035","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}

To reduce the overall comprehension effort it is therefore desirable to make the knowledge once gained explicit and shareable. We tackle this problem by establishing a mapping between source code and conceptualizations shared as ontologies. To achieve this we regard programs themselves as knowledge bases built on the programs' identifiers and their relations implied by the programming language. Making these mappings explicit allows sharing knowledge about the concepts represented in programs.
