Semantic Knowledge Sharing Mechanism Based on Blockchain
In the context of big data, the construction and query of existing knowledge graph are realized by gathering scattered knowledge into a centralized big data platform. However, with the advent of the era of knowledge sharing 3.0, the knowledge value awareness of knowledge owners has generally increased, and it has become increasingly difficult to concentrate knowledge on centralized big data platforms. Blockchain technology is a decentralized and distrusting technology solution proposed in recent years. Combined with blockchain, a decentralized semantic knowledge sharing mechanism based on blockchain is proposed. The decentralized global knowledge graph is constructed by using the inter-node communication mechanism, and the query mode and transaction flow design based on the mechanism are realized. The experimental results show that the semantic knowledge sharing mechanism based on blockchain proposed is feasible, and compared with the traditional centralized knowledge graph, the construction time and query rate are greatly improved.
