Decentralized Knowledge Sharing Mechanism Based On Rule Reasoning

With the continuous development of semantic web technology,the application of knowledge map is more and more extensive,and the application of knowledge reasoning is also increasing.The application of knowledge reasoning plays a great role in the construction of knowledge map,which greatly enriches and improves the knowledge map.Therefore,knowledge reasoning has become one of the hot topics.At the same time,with the advent of the era of knowledge sharing 3.0,the value of knowledge is more and more valued by people.Knowledge sharing has officially changed from free knowledge sharing to paid knowledge transaction,and a new era of knowledge payment is coming.Knowledge is not only the basic knowledge of triples,but also the knowledge of rules.Knowledge is becoming more and more important.Sometimes,the knowledge of rules is more valuable than the basic knowledge of triples,because rule knowledge can deduce multiple basic knowledge of triples according to rules.Therefore,it is of great significance to realize knowledge sharing of rule knowledge.Blockchain is a decentralized and distrusting technology scheme,which enables pointto-point cooperation or transaction between nodes without the need of trust basis.It is a decentralized idea formed by combining data encryption technology,economic game theory,distributed consensus mechanism,timestamp and other technologies.Therefore,this paper proposes a decentralized knowledge sharing mechanism based on rule reasoning,combining block chain and rule reasoning,to realize the sharing of rule knowledge.The main work of this paper is as follows: 1)a decentralized knowledge sharing mechanism based on rule reasoning is proposed,and the basic structure of the system is described;2)a decentralized query reasoning mechanism is proposed and implemented to ensure the independence and value of knowledge and complete the sharing of rule knowledge;3)designed and realized the decentralized trading mode of rule knowledge;4)designed and implemented a decentralized SPARQL complex query mode.In this paper,a decentralized knowledge sharing system based on rule reasoning is constructed,and a verification experiment and a comparison experiment are conducted.The experimental results show that the decentralized knowledge sharing mechanism based on rule reasoning proposed in this paper is feasible.It also has good effects on query rate comparison and knowledge integrity under this mechanism.The research in this paper provides a novel idea for the combination of knowledge graph and blockchain in the future and has certain research significance and economic value.
