The Technology Of Classification And Retrieving In The Teaching Test & Evaluation Domain's Component Library System And Implement Of Tools

The classification and retrieving of component are very important technology in a repository of reusable software components, and they already become an important basis of managing software components and reusing software components. They have been a hotspot of components repository recently. Especially for an immature and specific domain, they need be considered how to improve on and innovate in the classification and retrieving of component. This article research the classification and retrieving of component based on teaching evaluation domain.Firstly, I introduce developmental condition and resourceful result of software reuse, and the function and status of components repository in software reuse, and the classification and retrieving in components repository. Secondly, I study the current classification and retrieving in detail, and analyze their advantage and disadvantage, and get a common retrieving model and valuing standard. Thirdly, I according to the feature of the specific domain establishing the appropriate classification and retrieving of component, which are faceted classification and retrieving, and classification with DSSA and component's relationship and hyper text's retrieving, and combined retrieving. I establish the classifying model and retrieving model of the domain's components repository according to that. Lastly I accomplish the design and implement of components' classification and retrieving tools in the teaching evaluation domain.
