Abstract

The application discloses a method, a device, an electronic device and a storage medium for knowledge map completion, and relates to the field of big data technology. The specific implementation scheme is as follows: obtain the view instances of triplets in different viewing angles; input the view instances of different viewing angles into the target discrimination classification model, and obtain the comprehensive classification results of the triplets in all viewing angles; wherein, the comprehensive The classification results are used to characterize the effectiveness of the triplets. Therefore, the effectiveness index of a triplet can be measured from multiple different perspectives, so as to measure the effectiveness of the triplet more comprehensively.

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 ...
