Embodiment approach 1
[0162] Embodiment one, as follows:
[0163] It can be verified by comparison on JF7K and WikiPeople. These two public N-gram knowledge graph datasets are composed of relational facts in Freebase and Wikidata respectively. All training sets consist of training set, validation set and test set.
[0164] Specifically, each data set is divided into two sub-datasets of 3-element and 4-element, namely 3-element knowledge graph dataset JF17K-3, WikiPeople-3 and 4-element knowledge graph dataset JF17K-4, WikiPeople-4. The statistics of the dataset are given in Table 1 below.

[0166]
[0167] The following takes JF17K-3 as an example to introduce the process of implementing mode 1 to learn N-gram knowledge graph embedding and complete link prediction. The specific steps are as follows:
[0168] (1) Initialize the input 3-element knowledge map first, that is, randomly generate a low-dimensional vector with a length of...
