Abstract: As the research on reusable component deepening and the component repositories scaling up, representing, retrieving and adapting software components become a hotspot at present. However, traditional approaches result in low accuracy and efficiency when used in representing and retrieving software components. Moreover, the searching results will impede further adaptation of the components. To address these problems, a dimensional mapping model and relevant algorithm are proposed which integrate the divide-and-conquer and tree mapping ideas. The algorithm sufficiently improves the retrieving efficiency and accuracy, and it is also with linear time and space complexity.
