用统一网络表示BIM模型，融合语义、空间与拓扑关系。
Unified Network-Based Representation of BIM Models for Embedding Semantic, Spatial, and Topological Data
- 基于IFC标准扩展，构建包含局部空间与拓扑连接的网络结构。
- 能有效捕捉构件间的交互、依赖及隐含设计模式。
- 适合建筑信息建模、智能设计分析的研究者使用。
建筑信息模型（BIM）通过全生命周期的数字表达彻底改变了建筑行业。然而，现有研究缺乏有效方法来捕捉BIM模型中组件间复杂的空间与拓扑关系，这些关系对理解设计模式和提升决策能力至关重要。本研究提出一种统一的网络表示方法，整合BIM模型的‘语义-空间-拓扑’多维设计特征。通过扩展IFC（Industry Foundation Classes）标准，引入组件间的局部空间关系与拓扑连接以丰富网络结构。该表示方法使构件间的相互作用、依赖关系及隐含设计模式得以更详细地解析，有效捕获了BIM中的语义、拓扑与空间关系，具有显著的设计模式表征与学习潜力。
原文摘要 · Abstract (English)
Building Information Modeling (BIM) has revolutionized the construction industry by providing a comprehensive digital representation of building structures throughout their lifecycle. However, existing research lacks effective methods for capturing the complex spatial and topological relationships between components in BIM models, which are essential for understanding design patterns and enhancing decision-making. This study proposes a unified network-based representation method that integrates the "semantic-spatial-topological" multi-dimensional design features of BIM models. By extending the IFC (Industry Foundation Classes) standard, we introduce local spatial relationships and topological connections between components to enrich the network structure. This representation method enables a more detailed understanding of component interactions, dependencies, and implicit design patterns, effectively capturing the semantic, topological, and spatial relationships in BIM, and holds significant potential for the representation and learning of design patterns.
