摘要:

针对建筑行业对构件检索的迫切需求,提出一种面向工业基础类(IFC)数据特点的无监督建筑信息模型(BIM)构件检索方法。充分利用IFC标准中的语义和几何信息,构建了构件属性图(PAG)作为构件特征,并结合PAG的多属性通道,提出基于Weisfeiler-Lehman (WL)核增强的PAG同构预测思路,以实现BIM构件检索。该方法支持以2个IFC文档作为输入,其中文档A代表待检索的构件,文档B则为构件库,最终返回B中与A相似的构件。主要贡献在于:①提出一个无须数据预处理且兼容语义信息的BIM构件检索框架;②引入BIM构件的PAG特征构建方法,同时,给出WL图核增强的PAG同构预测方法;③设计了无监督的收敛性判断策略,通过分析预测结果中的属性差异及时判断算法的收敛状态。实验结果表明,该方法的PAG同构测试能在不超过3次迭代的情况下收敛,实验环境下BIM构件的同构测试不超过1 s,构件搜索的平均准确率达95%。

Abstract:

To meet the urgent need for building elements retrieval in the construction industry, an unsupervised building information modeling (BIM) product retrieval method tailored to the characteristics of industry foundation classes (IFC) data was proposed. The method fully exploited the semantic and geometric information from the IFC standard to construct a product attributed graph (PAG) as the product feature. By leveraging the multi-attribute channels of PAG, a PAG isomorphism prediction approach, enhanced by the Weisfeiler-Lehman (WL) kernel, was proposed to achieve BIM product retrieval. The proposed method accepted two IFC documents as input: Document A, representing the target product to be retrieved, and Document B, serving as the product library. Our method ultimately returned products from Document B similar to the target product in Document A. The principal contributions were threefold: ①The proposal of a BIM product retrieval framework that circumvented the need for data preprocessing while maintaining semantic integrity. ②The development of PAG feature extraction for BIM product and enhanced PAG isomorphism prediction method with augmented WL graph kernels. ③The design of an unsupervised convergence assessment strategy in which the convergence status was timely determined by analyzing the attribute differences between the attributes from source and those predicted. Empirical findings indicated that the PAG isomorphism testing of our methodology achieved convergence within a maximum of three iterations. Under the experimental conditions, the isomorphism testing of BIM products required no longer than 1 second, with an average accuracy rate of 95% in products retrieval.
