Embodiment

[0034] The overall architecture of the embodiment is as figure 1 As shown, follow the steps below to implement:

[0035] Step 1. Input the report of raw material inspection report (material_inspection_report) and concrete construction batching notice (construction_ingredient) from the mixing plant; input the report of test order (test_commission) and inspection report (concrete_product) from the laboratory; input concrete supply by the supervisory unit Contact form (material_application) and concrete construction ingredient notice (construction_ingredient) reports; third-party laboratories input raw material inspection (material_inspection_report) and concrete sampling inspection (concrete_sampling_inspection) reports to obtain raw data and save them in the local database.

[0036] Step 2. The above-mentioned units will further confirm the original data collected in step 1, delete duplicate data, modify wrong data, and obtain confirmed data.

[0037] Step 3, comprising the fo...

Abstract

The invention discloses a blockchain-based credible knowledge graph construction method in the field of water conservancy construction, and the method comprises the steps: 1) forming nodes by related units, obtaining original data through manual input, and storing the original data in a local database; 2) performing re-confirmation, error correction, duplicate removal and denoising on the original data to obtain confirmation data; 3) generating Merkel tree leaf child nodes and root nodes by using an SHA-256 Hash algorithm and a Merkel tree structure; (4) uploading the data to an Etherum public chain; 5) verifying the local database storing the confirmation data; 6) performing knowledge extraction on the local data to form RDF data and obtain a local knowledge base; and 7) uploading the RDF data to an alliance chain to form a latest credible knowledge graph about concrete production management. According to the method disclosed by the invention, the construction of the knowledge graph has the advantages of reliability, practicability, knowledge traceability and the like.

Description

technical field [0001] The invention belongs to the technical field of combining block chains and knowledge graphs, and relates to a method for building trusted knowledge graphs in the field of water conservancy construction based on block chains. Background technique [0002] The knowledge graph is essentially a semantic network that reveals the relationship between entities, and is mainly used to formally describe things in the real world and their relationships. With the development of science and technology, the application of knowledge graphs is becoming more and more extensive, such as providing auxiliary decision-making for securities investment and other enterprises, providing personalized education for students, and locating potential customers for the market. Therefore, the reliability of building knowledge graphs in various fields and higher requirements for accuracy. How to ensure the authenticity of source data in the process of building a knowledge graph? How...
