摘　　要：当前的成本预算软件对成本预算规范的支持,仍然需要依赖预算人员来实现相应的功能,对不同规范的支持也不够灵活。本体论可以用来对成本预算规范的知识和规则进行形式化表达,并支持进行灵活的扩展。本文通过对典型的成本预算规范的分析,实现了基于本体论的建筑工程成本预算规范表达,建立了一个基于本体论的建筑工程成本预算数据表达和利用框架,并阐述了该框架的适用性。该表达和框架为实现建筑工程自动成本预算奠定了基础。The support of existing software applications for construction cost estimation(CCE for short hereafter)for the specifications for CCE(CCE specifications for short hereafter) mostly depends on the estimators' manipulation in a large extent.Therefore,the proficiency of the estimators on CCE specifications greatly affects the efficiency and accuracy of CCE.In addition,the existing software applications cannot adapt well to the change in the CCE specification.Ontology provides a potential approach to establish a computerized and flexibly extendable representation of CCE specifications.In this paper,based on the analysis of a typical CCE specification,an ontology-based representation of CCE specifications is established.Then,an ontology-based framework for expressing and automatically utilizing CCE data is formulated and the generality of the framework is illustrated.The representation and framework lay a sound foundation for automatic CCE.
