This is usually done because of a lack of resource within the organisation: the software support staff could be busy on other projects, they could have a lack of expertise in the area of the work, or the job could just be too big to be done internally. Whatever the reason, bringing in an external contractor can have huge implications on the evolution of the software. As part of an evolution case study of a software product in use by the UK Royal Air Force (RAF), where third party contractor modifications were done on a regular basis, the implications of this third party work is being examined. The quality of the delivered software from both the in-house team and the contractor has been measured with particular attention to the software complexity. Preliminary results show that the software product experienced an increase of complexity throughout its evolution, specifically in the areas delivered by the contractors","PeriodicalId":306640,"journal":{"name":"2006 13th Working Conference on Reverse Engineering","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124097804","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}

Version control repositories contain information on several thousand of files and on millions of changes. We propose an approach based on dynamic time warping to discover change-patterns, which, for example, describe files that change together almost all the time. We define the synchrony change-pattern to answer the question: given a software system and one file under modification, what others files must be changed? We have applied our approach on PADL, a software system developed in Java, and on Mozilla. Interesting results are achieved even when the discovered groups of co-changing files are compared with these provided by experts","PeriodicalId":306640,"journal":{"name":"2006 13th Working Conference on Reverse Engineering","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128882615","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 key information extracted from these repositories gives a picture of the changes on the software system. To have a complete picture, tailored to the needs of the developer, the extracted data needs to be filtered, aggregated, and presented to the users. In this paper we propose a new visualization for such data, which relies on an existing software visualization front-end, SourceViewer3D (sv3D). The new visualization allows users to define multiple views of the change history data, each view helps answer a set of questions relevant to specific maintenance tasks. Data can be viewed at different granularity (e.g., file, line of text, method, class) and comprehensive views can be defined, which display to the user multiple data types at the same time. Complex questions and tasks can be solved with the aid of such views","PeriodicalId":306640,"journal":{"name":"2006 13th Working Conference on Reverse Engineering","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123370997","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 addresses this situation by proposing a common framework based on crosscutting concern sorts which allows for consistent assessment, comparison and combination of aspect mining techniques. The framework identifies a set of requirements that ensure homogeneity in formulating the mining goals, presenting the results and assessing their quality. We demonstrate feasibility of the approach by retrofitting an existing aspect mining technique to the framework, and by using it to design and implement two new mining techniques. We apply the three techniques to a known aspect mining benchmark and show how they can be consistently assessed and combined to increase the quality of the results. The techniques and combinations are implemented in FINT, our publicly available free aspect mining tool","PeriodicalId":306640,"journal":{"name":"2006 13th Working Conference on Reverse Engineering","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123855537","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}
