| Summary: | 碩士 === 國立雲林科技大學 === 資訊管理系碩士班 === 94 === Composing existing components to form a composition component help components are able to work in coordination each other. It is useful that component composition decreases the cost of component development and facilitates component to be reused. Ontology can reasonably describe and represent knowledge structure. Our approach employs the task ontologies and domain ontologies to describe component conditions. Fit semantics into description of component, then composed a component composition be able to work in abstractive framework. Our algorithm can search appropriate component which conform requests of component requester.
In the topic of component composition, precondition and postcondition involved in the usability of component composition. In our research framework, we describe the input parameter, output parameter, precondition and postcondition of component’s method, they are specified by linking component’s method with concept of domain ontology. Searched components can synergistic effect to finish a task by this kind of abstract represent.
The description of task disasseme degree and different conditions restrain will make the Searching and Composition of Component be complicated. Different component conditions restrain will result different compare problem, our Research develop multiple-layer searching and comparing tactic to solve these problem. Our tactic will make the reuse rate of components increase.
