Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0049]In one embodiment, such as figure 1 As shown, a method for authenticity detection of triples in a knowledge graph is provided, including the following steps:

[0050] Step 102, extracting a first vector describing triplet structural information in the knowledge graph and a second vector describing triplet description information in the knowledge graph from the text.

[0051] The first and second are only limitations for distinguishing two vectors, and have no practical meaning. In the knowledge graph, the triplet structure is (head, relation, tail), head refers to ...

Abstract

The invention relates to a method and a device for detecting authenticity of triples in a knowledge graph. The method comprises the following steps of: forming a substrate; extracting a first vector for describing triad structure information in the knowledge graph and a second vector for describing triad description information in the knowledge graph from the text; fusing the first vector and thesecond vector; obtaining fusion vectors, according to a preset network structure of a capsule network, constructing a scoring function used for defining a triple score, scoring function, constructinga loss function for training a capsule network; constructing a sample set according to the fusion vector, training the capsule network model according to the sample set and the loss function to obtaina trained capsule network, inputting the fusion vector corresponding to the a to-be-predicted triad into the trained capsule network, and determining whether the relationship of the triad is accurateor not according to the output value of the scoring function. By adopting the method, tThe accuracy of triple authenticity detection can be improved.

Description

technical field [0001] The present application relates to the technical field of knowledge graphs, in particular to a method and device for detecting the authenticity of triples in knowledge graphs. Background technique [0002] Since Google first proposed the concept of knowledge graph in 2012, it has developed in the field of artificial intelligence at a very fast speed. Today, research and work related to knowledge graphs play a pivotal role in various fields of artificial intelligence. For its part, knowledge graphs are usually stored as triples (head, relation, tail). Triplets can characterize the internal structure and relationships of graphs. In recent years, research on representation learning, relation prediction and graph completion is the foundational part. They are also the most important part of the knowledge graph. There are many related methods, such as TransE (Bordes et al., 2013), DistMult (Yang et al., 2014), ComplEx (Trouillon et al., 2016), ProjE (Shi...
