Research on the Formal Description and Fuzzy Retrieving of Component

As going deep into the study of the software reuse,the accurately describing of software component and high efficiency of component retrieving are become the hotspot and nodus of the studying of the software reuse.In this article,by the reference of 3C model of software component,we put forward a formable,extensible describe model of component,including function describe,interface describe,environment description,etc,and we keep the keyword list and unfunctional attribute description,by this way,we bring forward a multiple steps searching method of component,and emphasize on the discussion on of the four levels of fuzzy searching of component,in order to raise the efficiency of the component searching and take care of the full-scale of the searching results.
