Software reuse is widely believed as a feasible way to improve both the productivity and quality of software development. The developers must be capable to acquire enough desired components before developing with reuse. Many Internet-enabled reuse repositories exist to provide access to reusable resources. It is necessary to eliminate the semantic gaps of the repositories to enable users to access resources from multiple repositories via a single representation view. In some sense, the only usable information to mine the semantics of the terms representing the resources is the mutual components stored in the repositories. In this paper, the extended improved relevancy matching and ranking (EIRMR) method is proposed to enhance the semantic interoperability of reuse repositories, based on our previous work (IRMR) and the mutual components in the third-party repositories. Experimental results on the data sets from the real repositories demonstrated an improvement in terms of searching effectiveness.
