Software reuse is a promising solution to the software crisis. Reuse repositories are the basic infrastructure for software reuse. During the past decade, various academic, commercial, governmental, and industrial organizations have developed many Internet-enabled reuse repositories to provide access to software components and related resources. It has necessitated semantic interoperation to allow distributed maintenance and management of these repositories while enabling users to efficiently

... d conveniently access resources from multiple reuse repositories via a single representation view. In this paper, we have proposed an approach to enhancing the semantic interoperability of reuse repositories, called the improved relevancy matching and ranking (IRMR) method, based on analyzing the correlation of terms in representation methods of the repositories. A prototype system, the Virtual Repository supporting Semantic Interoperation (VRSI), is presented to illustrate the application of this approach to support the semantic interoperation of reuse repositories. Experimental results on real world reuse repositories demonstrated significant improvement in terms of searching effectiveness.
