Abstract


Software reuse is regarded as an effective way to improve software productivity and quality, and how to find a library of reusable software components required component is a need to address the problem. With the extensive application of network technology, reusable components of the different components of the model will continue to increase, and the ability to provide an effective tool or method, enables developers to retrieve components to comply with the new system needs to become a core component-based software development faces problems. Component description and retrieval, retrieval, such as the description and classification based on faceted member described the lack of semantic information of components difficult to accurately retrieve member resources to match demand, precision rate and the recall rate is not high. Faceted introduced the concept of the body, facet-based component classification and description of the structure set up, establish-member body, and the body retrieval requests submitted by a user semantic extensions to improve the precision of component retrieval rate and check full rate. On how to take advantage of the body from the point of view of the ontology semantic the component retrieval research. The main work: the first analysis of the the representative component library system of classification and retrieval technology, focusing on member faceted classification Faceted program members propose the use of XML technology, introduces XML tree matching model features. Reference to the relevant academic achievements at home and abroad, given specific Faceted achieve in order to establish a data model of software component library components. Ontology definition, description of methods, build tools, and how to build the research, using the OWL language to describe the body, formally defines the relationship between the concept and the concept, an object-oriented domain ontology CEM (Higher Education Management) and in accordance with the methods established domain ontology. Member faceted search based on the introduction of the body, combined with faceted classification of information and field information, establish a reasonable software component ontology model for semantic retrieval software component. The model combines a faceted classification of information and field information of the component, and take full account of the semantic integrity of the body. 4. Proposed model and algorithm based on the combination of body and Faceted search, and realized the components generated assembly platform (CPAP). Finally, summarize the main work of this paper, and look forward to the next phase of work.
