Component-Based Software Development (CBSD) is becoming increasingly more important in software engineering research and software development; however, it encounters many problems regarding its application. Here, based on the active repository system CodeBroker, the authors introduce a new approach to push components to end users according to their personalized information. The integration of the component repository, retrieval methods, queries, and the developer coding process reduces the CBSD cost on training, as well as renders CBSD applicable in research. Framework of this approach containing the following modules: building domain ontology, repository access agent, code analysis, personality catch and ontology-based component retrieval and push. Our experimental evaluation of the SourceForge projects on database field shows that suitable components can be automatically pushed to user through this approach. Using ontology reasoning and personality filtering, the proposed approach can improve the quality of the search results.
