SOFTWARE COMPONENT IMPORTANCE EVALUATION SYSTEM

摘要

A system for measuring the importance of reuse of software on the basis of a n objective criterion. At a file relationship extracting step (S212), a Java source code file (230) is analyzed and the class-to-class inheritance is extracted as a reuse relationship. At an SMMT step (S222), the similarity between Java source code files (230) is calculated. At a step (S224), cluste r analysis is carried out on the basis of the similarity calculated at the SMM T step (S222), and the files are categorized into M component groups. Based on the results of the cluster analysis (S224) and the extraction of the relationship between files (S212), the relationship between the component groups is extracted (S214). Evaluation by using the relative importance evaluation value of the component groups is carried out on the basis of the relationship between the component groups (S216). Lastly, the relative importance evaluation of the component groups is converted into the evaluati on of the file (software component) (S218).
