【摘要】 分析了本体驱动的信息系统集成与互操作的数学基础,提出了一种新的具有分布计算能力的本体的代数模型,并应用到地理信息系统的集成和互操作中.新代数模型能够提高系统的可伸缩性并降低维护代价,可以将分散在Internet上的地理信息系统开放和动态地集成在一起,有效地提高了分布异构GIS的语义互操作能力.更多还原

【Abstract】 Based on the mathematic base of information system’s integration and interoperation,the article produces a new Algebra model with the entity of distributing calculating ability,and uses it in the integration and interoperation of Geographical Information System.This new model can improve the system’s flexibility,reduce the cost of maintenance,and have an open and dynamic collection of Geographical Information System dotted in the internet so as to improve the efficiency and accuracy of the interoperability of Geographical Information System.更多还原
