Abstract


The software development of the member - based put forward the the software component multiplexed with , in through the to of reusable the with the components to design and tectonic software system . This kind developers way not only can to improve the the the software the quality and productivity of , also can to reduce the the the the cost of of software development and maintenance . However , With the the the constantly to expand of the the the scale of of the on Software Component Library , in the the in the component library retrieval to the the Subject to the components of of the the multiplexed with demand become very difficult to . In the the traditional the the component retrieval of method of in the , keyword - based of the retrieval the use of of simple , However, due to the the the the synonymous with the multi-word of of the natural language with the the polysemy , makes the the the component retrieval matching become very difficult . In the the the in the the classification retrieval of of based on Faceted , due to to the the the relationship between in the the engraved surface between the terms is overly a single , as well as the lack of the a specific semantic information in the field of , lead to the not be able to the use of in the matching the process of the the semantics carried out reasoning , thereby reducing the a the component retrieval of the Zha quasi- rate of and search of the a wholly- rate of , Failed to to meet the the the needs of of the user's retrieval . Against the to the the lack of in the the the the component retrieval described in by the engraved surface the the the problem of of the semantic information , In order to improve the the the engraved surface classification retrieval the of the Zha quasi- rate of , combined with the domain ontology , put forward a the model of the component description of based on ontology . The the function of of the model in order member as the foundation, and respectively is described aspects conducted to the from the a member function, non functional attributes and quality attributes Triple . And then in-depth to analysis of a based on to the the the the the matching algorithm of of the semantic distance and the the precise that match the query algorithm , combined with the this two algorithms is given the algorithm of a the of this article by the to use of the component matching . In the the the the a retrieval the process of , through the the the the interactive query of the the user's to guarantee the the rate of of the component retrieval of the Zha quasi- . The establishment of in the the the preliminary experimental results of the上海构件库show that the , with the the compared to the the the traditional engraved faceted classification retrieval method , the the the retrieval method of the of this article not only can improve the the The retrieval precision was , has also been strengthened the the flexibility of of retrieval .
