摘要
为使极限与配合知识既能满足知识重用和语义互操作的需求,又具有较高的数据访问效率,以共享概念和数据存储两层结构组织极限与配合知识.以极限与配合本体作为共享概念层,以关系型数据库存储极限与配合数据,以映射连接极限与配合本体和数据库,从而可通过极限与配合本体直接访问极限与配合数据.在满足极限与配合知识重用和语义互操作需求的同时,保证了极限与配合数据的访问效率.通过原型系统和基于该系统的工程实例,验证了基于本体的极限与配合数据访问的可行性和有效性.
To meet both the needs of reusability and semantic interoperability of limits and fits knowledge and the needs of limits and fits data access performance, the tier structure of shared concepts and data storage is introduced to organize the limits and fits knowledge. Considering the limits and fits ontology as the shared concepts, we manage the limits and fits data with relational database management system and express the relationship between the data and the concepts by mappings. Then the limits and fits data can be accessed through the limits and fits ontology. In this way, the needs of limits and fits knowledge reusability and semantic interoperability are met, while ensuring the efficiency of limits and fits data access. The feasibility and effectiveness of ontology based limits and fits data access are demonstrated by a prototype system and a practical example.
