Claim 1:
2. The method for visual construction of a knowledge graph system according to claim 1, wherein the user registers and logs in the distributed client, and after being authorized by the central server, an identity account number is assigned for each user, and a message of successful registration and log-in is fed back to the user;
wherein the data permission request is made by the user in the distributed client, the central server approves or rejects after receiving the data permission request, and when the data permission request is approved, a next step is performed; otherwise, a follow-up flow is interrupted;
wherein the user inputs a target database address of the knowledge graph system to be constructed into the distributed client, and the distributed client sends the target database address to the central server in a mode of an HTTP request carrying user cookie; and
wherein the central server performs HTTP parsing, a user identity is confirmed through the parsed user cookie, identity and data permission verification is performed; when the identity and data permission verification is passed, a next step is performed; otherwise, the data permission request is rejected.
