Abstract: A method, apparatus, device, and storage medium for expanding data are disclosed. The method includes: acquiring a triplet from a knowledge graph; mining a relationship path equivalent to a relationship in the triplet from the knowledge graph, a subject in the triplet being used as a start point of the relationship path, and an object in the triplet being used as an end point of the relationship path; and expanding the triplet based on the relationship path to generate an expanded triplet. This implementation expands the triplet in the knowledge graph, and strengthens the association between the subject and the object in the triplet in a larger context, such that the association between the subject and the object in the triplet is more global.

Abstract: The present application discloses a data transmission method and system. A specific embodiment of the method includes: receiving a data transmission-instruction by a data sender, wherein the data transmission-instruction includes a thematic name indicative of a type of to-be-transmitted data required by a data receiver; creating a shared memory segment corresponding to the thematic name. It makes possible for the data sender and the data receiver to run in a separate memory space. When data is needed to be transmitted, a corresponding shared memory segment may be created for data transmission in accordance with any transmitting requirement, and the shared memory segment may be released when the transmission is done or appears abnormal. On one hand, it reduces the redundant operations of the data transmission system during data transmission, and improves the data transmission performance; on the other hand, the data transmitting procedure between the data sender and the data receiver, and other operations executed by the data sender or the data receiver are independent of each other, which improves the stability of the data transmission system.
