Research on Decentralized Distributed Knowledge Graph Scheme Based on Blockchain

the rapid growth of the scale of knowledge graph, the demands for constructing decentralized distributed knowledge graph are becoming more urgent. There are some attempts in this aspect. But there are still many challenges to be addressed: (1) Lack of a credible multi-party collaboration environment for distributed knowledge graph. (2) Lack of effective knowledge quantification and sharing incentives mechanism. In order to these two problems, we propose a framework and technical architecture of decentralized distributed knowledge graph based on blockchain in this paper. Then, we analyze the importance of contribution confirmation and quantification of knowledge, and propose the methods of knowledge quantification and sharing incentives in distributed knowledge graph. Finally, the future research direction of the scheme is proposed including more fine-gained value quantification, privacy security and blockchain performance optimization in decentralized distributed knowledge graph.
