With ongoing advancements in information and communication technologies (ICTs) in all stages of the construction lifecycle, information from entities related to construction workflow (CW) can now be automatically collected. These implementations are point solutions, which require systematic integration to combine their information to enable a holistic picture of CW. The major barrier to such integration is information heterogeneity, where the information is collected from different systems under multiple contexts. Scholars in the construction domain have explored the use of ontology to solve the information-integration problem, although an ontology that both adequately represents the CW and integrates the digitalized information of CW via various systems and multiple contexts is currently missing from the existing literature. This research thus presents an ontology set for formalizing and integrating CW information within the digital construction context. The proposed digital construction ontologies (DiCon) are shared representations of construction domain knowledge that specify the terms and relations of CWs and their related information. We developed the DiCon based on a hybrid ontology development approach. The DiCon includes six modules: Entities, Processes, Information, Agents, Variables, and Contexts. The developed DiCon was further evaluated by approaches including automatic consistency checking, criteria-based evaluation, expert workshops, and task-based evaluation and involved two use cases by answering relevant competency questions via SPARQL queries. The results of the evaluation demonstrate that the DiCon ontologies are sufficient to represent domain knowledge and can formalize and integrate CW information within the digital construction context.

随着信息和通信技术 (ICT) 在施工生命周期各个阶段的不断进步，现在可以自动收集来自与施工工作流 (CW) 相关的实体的信息。这些实施是点解决方案，需要系统集成以组合其信息以实现 CW 的整体图景。这种集成的主要障碍是信息异质性，其中信息是在多种环境下从不同系统收集的。构建领域的学者已经探索了使用本体来解决信息集成问题，尽管现有文献中目前缺少一种既能充分表示 CW 又能通过各种系统和多种上下文集成 CW 数字化信息的本体。因此，这项研究提出了一个本体集，用于在数字建筑环境中形式化和集成 CW 信息。提议的数字构建本体（DiCon）是构建领域知识的共享表示，它指定了 CW 及其相关信息的术语和关系。我们基于混合本体开发方法开发了 DiCon。DiCon 包括六个模块：实体、过程、信息、代理、变量和上下文。通过自动一致性检查、基于标准的评估、专家研讨会和基于任务的评估等方法对开发的 DiCon 进行了进一步评估，并涉及通过 SPARQL 查询回答相关能力问题的两个用例。
