Domain Knowledge Graph Construction Methods of Construction Schedule in Steel Structure Projects

In the domain of engineering construction, steel structure engineering construction has accumulated a large amount of data, and the development of knowledge graph construction technology to structure this data can provide effective support for high-quality construction organization. This paper analyzes the knowledge sources of construction schedule for steel structure projects, constructs a domain ontology of construction schedule for assembled steel structure projects by using a seven-step method and points out the current problems of knowledge extraction for construction organization design for assembled steel structure projects. The semi-structured construction schedule data is subject to event extraction, and the unstructured knowledge of construction schedule is discussed from the perspective of few-shot methods and large language modeling for the knowledge extraction of construction schedule for steel structure projects.
