Multi-valued constant propagation analysis (MVCP) is needed to extract user interface behavioral specifications from source code. Structural and behavioral specifications are used to generate new user interface code that will be integrated into the original system. The flow analysis aspects involved in the MVCP approach are described together with an overall view of the user interface reengineering project. The motivations and advantages of such an analysis method are presented.<<ETX>>","PeriodicalId":228379,"journal":{"name":"1993 Conference on Software Maintenance","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123268704","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 method and results of an experience of metric-aided clustering of software components, aimed at detecting and characterizing implicit reuse of code and reuse potential in a large-scale data processing environment, are presented. Similar function may be in fact replicated many times, customizing an existing source code component, but this phenomenon may be only partially apparent in the form of explicit reuse. A set of software metrics has been used to create clusters of existing components whose internal structures appear very similar. Functional similarity checks involving human experts were then performed. This was done in the context of a large reuse project, where quantitative software quality indicators are also combined with the feedback collected in pilot groups who know the applications from which the candidate components were extracted. The potential and limitations of metric support in this field are considered in the discussion of the results obtained.<<ETX>>","PeriodicalId":228379,"journal":{"name":"1993 Conference on Software Maintenance","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129999236","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}

Direct slice is an executable subset of the original program containing all the statements which directly contribute either to the writing on an external sink or to the reading from an external source.

A prototype tool is described which demonstrates the feasibility of the method. The tool is used to analyze a C program, and a number of abstract data types are identified and used in the maintenance of the original program.
