The present invention provides a knowledge graph construction method and device. The method includes: obtaining structured data, where the structured data includes a first entity name of a first entity and attribute information corresponding to the first entity name, and the attribute information includes a first attribute and a first attribute value; performing, based on measurement of a similarity between the first entity and a second entity in a knowledge graph, entity alignment processing on the first entity, where the measurement of the similarity includes at least one of the following types: measurement of a character similarity, measurement of a structure similarity of a classification tree on which an entity is located, and measurement of an attribute similarity; and importing the structured data into the knowledge graph according to an entity alignment processing result. Embodiments may ensure correctness of data in the knowledge graph.

Knowledge graph construction method and device

Provided are a multi-functional stratigraphic structure model testing system and testing method. The system includes a test piece testing device platform that includes a watertight fan-shaped closed cavity, a fluid-solid coupling loading system, and an anti-arc reaction frame system. A coupling loading system region consist of hydraulic (liquid) loading and multi-directional solid-skeleton loading onto a pore or crack test piece, which can be independently operated or combined with each other's. The fan-shaped closed cavity is fixed through the anti-arc reaction frame system, and a fan-shaped center region is provided with an application region of underground working face. The other two flat fan sides are provided with application regions of physical and chemical improvement for surrounding rock.
