基于本体的建筑信息上下文建模

Ontology-based Approach to Context Modeling for Construction Information

针对当前建筑领域信息利用效率低下,信息共享与重用难等问题,文章将上下文信息引入到本体模型中,构建了基于本体的建筑信息上下文模型,可以快速有效地对建筑信息进行管理。该模型包括用户上下文和工程上下文,并以小型加油站建设为例进行具体说明,首先利用Protégé建立了上下文本体模型,然后利用OWL公理和SWRL规则建立知识模型,最后利用推理机对模型进行推理,并通过案例说明基于本体上下文建模的优势。实验结果表明:文章提出的基于本体的上下文建模方法可有效地管理建筑工程信息,可快速有效地对建筑信息进行推理,为施工过程中的计划管理和进度管理提供了较好的支持。

To solve the problems of inefficient utilization, difficult information sharing and reuse about construction information, this paper introduces context to ontology model, and builds an ontology-based context model for construction information. The proposed model can quickly effectively manage construction information. The context model includes two separate processes： context model definition and verification process, and an engineering of the small gas station construction is provided to illuminate. First, the context ontology model is built by Protrgr. Then the knowledge model is listed by OWL axiom and SWRL rules. Finally, the paper discusses the challenges for context modeling and reasoning, and presents a case study to demonstrate the advantage of the proposed ontology-based context model. The verified result shows that the proposed approach contributes to manage construction information, infer construction information quickly and effectively, increase the effectiveness of schedule management and provide better support for schedule management.
