Claim 6:
7. The method for visual construction of a knowledge graph system according to claim 5, wherein the user inputs knowledge concept α and knowledge graph depth θ when the distributed client requests for using the knowledge graph system, and the distributed client sends a two-tuple (α,θ) to the central server in a manner of an HTTP request;
wherein the central server reads the stored cipher text (p′,q′,l′) from the tree structured database, the triple information (p,q,l) is decrypted and restored, the two-tuple (α,θ) is read, a search condition is set as using α as a root node and child nodes in a set l as search nodes, θ-layer recursion search is performed in the tree structured database, and the tree structure knowledge graph r is obtained and sent to the distributed client in a form of an HTTP; and
wherein the distributed client parses the tree structure knowledge graph r and renders to generate the knowledge graph meeting the input requirement.
