Abstract

Searching and subsequently selecting reusable components from component repositories has become a key impediment for not only component-based development but also for achieving the overall usability of component development environments and the ultimate re-usability of the components themselves. Component matching, a fundamental aspect of the component search problem, has been a well-studied problem, resulting in many different matching techniques such as keyword, facet, signature and specification matching techniques. However, each matching technique individually applied for component search often yields a small or large number of (sometimes irrelevant) hits. In this paper, we propose a disciplined combination of the different matching techniques to provide a ranked set of highly qualified components from component repositories. Our work is based on a unique Quality of Match (QoM) metric that measures the overall “goodness” of the match between two given components. In particular, we provide qualitative and quantitative analysis to evaluate the QoM of two given components based on component information. Moreover, we present QoMym, a QoM-based hybrid match algorithm, that combines the strengths of different matching techniques and provides higher accuracy than existing matching techniques.
