Abstract: To ensure the quality of steel structure buildings, a compliance review of the construction plans developed during the preparation phase is essential. To address the issues of low efficiency and high subjectivity in the current compliance review process, the implementation of automated compliance review utilizing knowledge graphs is proposed. Based on the Code for Welding of Steel Structures GB50661 - 2011, this article improves the word segmentation effect by introducing the phrase cohesion degree and phrase freedom degree on the basis of analyzing the characteristics of the provisions. It extracts triples by using semantic role labeling and dependency syntactic analysis and stores them in Neo4j to complete the construction of the knowledge graph of this specification. Using the compliance review of a specific steel structure factory construction plan as an example, the application of knowledge graphs combined with a breadth-first algorithm facilitates the compliance review process, thereby demonstrating the feasibility of using knowledge graphs for compliance review of construction plans.
