A weight matching method for component matching technology based on ontology

Components retrieving and matching are key technology of component-based software development (CBSD). Recently, component matching has two main problems. One is redundancy and irrelated components increasing because of not taking advantage of component tree-structure, and the other is the difficulty of understanding and sharing of components. An uniform component description model which makes use of XML Schema organizes components hierarchically, and we propose a maximal weight matching method for calculating matching degree of components in semantic and syntax. It is proved that it can not only help users to lookup the component, but also improve the precision of the searching.
