Problems solved by technology

[0005] In view of the poor reliability of the current knowledge graph, the uneven level of knowledge quality, the high cost and high barriers to constructing the vertical domain knowledge graph, the present invention proposes a method for verifying and updating the knowledge graph based on the distributed double consensus of the block chain. The knowledge excavated by each node is verified by the double consensus mechanism to complete the verification of new knowledge, and finally build an authoritative and accurate domain knowledge map, and introduce the virtual currency incentive mechanism of the blockchain to stimulate more participants to actively provide high-quality and efficient knowledge to make the entire construction process sustainable

Embodiment Construction

[0028] The present invention will be described in more detail below in conjunction with the accompanying drawings and the construction and verification of the knowledge map of power defects in the power field as examples.

[0029]Step 1: All distributed machine nodes i participating in the verification mine new knowledge for the power defect log of the machine node, power defect field literature and power field web pages to form a local knowledge base; where i=A, B, C, D..., which ensures the diversity of knowledge sources, and the irrelevance of knowledge mining methods ensures the accuracy of knowledge verification in step 4; the information stored in each block in the blockchain includes: the latest in RDF form Stored knowledge graph, reward transaction information and timestamp, RDF is the resource description framework;

[0030] Step 2: If figure 1 As shown in the process, after all machine nodes complete the new knowledge mining, each machine node downloads the knowledg...

Abstract

The invention discloses a method for verifying and updating knowledge graphs based on distributed double consensus of block chains, which includes the following steps: all machine nodes i perform local new knowledge mining, and match with the latest knowledge graphs of the original block chain to find differences knowledge to form a knowledge list; all machine nodes share the knowledge list to other machine nodes to form a total task table S i ; The main machine node sends the node S p The entity relationship pair k in the network is broadcast to other machine nodes in order to verify whether the entity relationship pair k corresponding to each number n of the main machine node p is provided by the machine node i; when the main machine node p receives f+1 Confirm After the message, the consensus on S p The entity relationship within initiates local verification for k; when the main machine node p receives more than f+1 local-complete messages, it updates the latest knowledge graph and rewards node i with virtual currency for entity relationship k. A new knowledge map and this transaction are written into the blockchain.

Description

technical field [0001] The present invention relates to the technical field of the combination of block chain and knowledge map, in particular to a knowledge map verification and update method based on block chain distributed double consensus. Background technique [0002] The essence of the knowledge graph is a knowledge base based on the semantic network, which is mainly used to describe concepts, entities, events and the relationship between them, and is usually stored in the form of triples. With the development of science and technology, the application of knowledge graphs is becoming more and more extensive, such as providing decision-making assistance for enterprises, locating potential customers for the market, updating domain knowledge in real time for newcomers in the field to learn, and so on. Therefore, various industries have put forward higher requirements for the reliability and accuracy of knowledge graphs. When the knowledge map introduces new knowledge, it...
