Abstract

The invention discloses a SPARQL statement reordering method and device, and a SPARQL reordering-based BIM model checking method and device. The checking efficiency of a BIM model can be improved. The method comprises the following steps: determining a target component according to a predicate of an SPARQL check statement generated based on a building rule description language (SNL) rule; grouping the multiple SPARQL check statements, dividing the SPARQL check statements related to the same target component into the same group, and obtaining SPARQL check statement fragments of different target components; traversing the SPARQL check statement fragment of each target component, if both the subject and the object in the currently traversed SPARQL check statement are components, connecting a directed edge from the SPARQL check statement fragment taking the subject as the target component to the SPARQL check statement fragment taking the object as the target component, and generating a component relation constraint graph after traversing is finished; according to the component relation constraint graph, reordering SPARQL check statement fragments of different target components, and obtaining SPARQL check statements corresponding to the SNL rules after reordering.

Description

technical field [0001] The present invention relates to the field of architectural technology, in particular to a SPARQL sentence reordering method and a device for checking a BIM model based on the SPARQL reordering. Background technique [0002] BIM (Building Information Model, Building Information Model) is a three-dimensional model-based technology for building information applications, which can be effectively applied to the planning, design, construction, management and other stages of buildings and infrastructure. One of the most developing technologies. In the process of BIM technology promotion and implementation, the realization of building code review based on BIM model plays an important role in promoting the progress and development of BIM industry. [0003] In related technologies, BIMChecker, a building code review tool, can be used to review the BIM model, so as to determine whether the building corresponding to the BIM model complies with the code. The bas...
