Title:
METHOD AND APPARATUS FOR EMBEDDING RELATIONAL NETWORK DIAGRAM
Document Type and Number:
WIPO Patent Application WO/2020/015464
Kind Code:
A1
Abstract:
Provided by the embodiments of the present description are a method and apparatus for embedding a relational network diagram into a multidimensional space, the method comprising: randomly determining an initial embedding vector Ci of each node i in a multidimensional space; obtaining neighbor nodes of each node i and the strength of association thereof with each neighbor node; determining a current embedding vector of the each neighbor node of the node i; forming a position initialization item and a position offset item of the nodes i on the basis of a predetermined attenuation coefficient, the strength of association and the current position of the neighbor nodes, and determining a current embedding vector of the nodes i accordingly; repeating the described steps until a convergence condition is satisfied, at which time the embedding vector of each node i in the multidimensional space may be determined. Thus, a relational network graph is efficiently embedded into the multi-dimensional space.
