Abstract

The invention discloses a knowledge graph completion method and a device, electronic equipment and a storage medium, and relates to the technical field of big data. According to the specific implementation scheme, the method comprises the steps of obtaining view instances of a triple at different view angles; inputting the view instances of different view angles into a target discrimination classification model, and obtaining a comprehensive classification result of the triad at all view angles; wherein the comprehensive classification result is used for representing the effectiveness of the triad. Therefore, the effectiveness index of one triad can be measured from a plurality of different perspectives so as to more comprehensively measure the effectiveness of the triad.

Description

technical field [0001] The present application relates to big data technology in the field of data processing, and in particular to a method, device, electronic device and storage medium for knowledge graph completion. Background technique [0002] Knowledge graph completion aims to make up for the missing information in knowledge graphs, and is an important technology for knowledge graph construction. The knowledge map is a graph structure composed of (h, r, t) triples, where h (short for head) and t (short for tail) are the head entity and tail entity respectively, and r (short for relation) is the connection Relationship between head and tail entities. The task of knowledge graph completion aims to find missing triples for knowledge graphs, and its core problem is to judge the validity of a given candidate triple. [0003] At present, the knowledge map can be completed based on the discriminative classification method of the convolutional neural network (CNN). Perform ...
