Discovery method and device for open hierarchical structure relationship and electronic equipment

Abstract

The invention provides a discovery method and device for open hierarchical structure relationship and electronic equipment. The method comprises the steps of determining to-be-tested statements based on a new corpus; inputting each to-be-tested statement into a relationship representation model, and outputting a corresponding relationship representation vector; clustering relationship representation vectors of all the to-be-tested statements, and determining a new relationship type; inserting the new relationship type into the original hierarchical structure relationship based on a preset rule; wherein the relationship representation model is obtained by training based on sample statements in the original hierarchical structure relation and corresponding relation type labels, and a loss function used in the training process of the relationship representation model is constructed based on dynamic hierarchical triple loss. According to the discovery method and device for the open hierarchical structure relationship and the electronic equipment, the relationship type in the original hierarchical structure relationship is better understood, and the found new relationship is automatically added into the existing original hierarchical structure relationship.

Description

Technical field [0001] The present invention relates to a new technique of relationships, and more particularly to discovery methods, apparatus, and electronic devices for open hierarchical relationships. Background technique [0002] Due to the explosive growth of the network era, the text on the network will appear daily, there are many important information such as individual entities, such as addresses, institutions, celebrities, and a number of statements that are contacted between the entities, such as "Mr. A graduated from the University '" Describes the inner links of' A. In order to fully utilize this information, the knowledge maps are expressed in the situation of all entities and entities. For example, the above-mentioned representation is (Mr. A, in ... I am at school, B University). Fully excavation and maintaining these entities, the relationship can help a large number of downstream tasks such as knowledge quiz and knowledge reasoning. [0003] Although existing k...

Problems solved by technology

[0007] The present invention provides a method, device and electronic device for discovering open hierarchical structure relationships, which are used to solve the problem that the information in the existing hierarchical structure is not used to help the model understand the relationship better, and the novel relationship cannot be automatically added to the knowledge map For the problem of hierarchical structure, the relationship representation model trained based on the relationship type labels in the original hierarchical relationship and the corresponding sample sentences is used to encode the new sentences to be tested in the corpus to be tested and output the corresponding relationship representation vectors. Based on the relationship representation The vector clusters the relationship types of the new sentence to be tested to determine the new relationship type, and finally inserts the new relationship type into the original hierarchical structure relationship with preset rules, and the loss function used in the training process of the relationship representation model is based on the dynamic Hierarchical triplet loss construction
