Problems solved by technology

[0003] In the existing technology, the relationship between entities in the market-related knowledge graph is mainly obtained based on the co-occurrence data of entities. However, this method can only obtain the co-occurrence relationship between entities. If you want to accurately To obtain the real relationship between entities, it is necessary to manually collect the relationship between entities and add it to the knowledge graph. This method of manually collecting the relationship between entities is relatively inefficient and expensive

Abstract

The embodiment of the invention provides an entity relationship obtaining method and device. According to the embodiment of the invention, a text fragment containing every sample group is extracted from a webpage text according to at least one sample group in accord with appointed relationship, wherein every sample group comprises two sample entities; data generalization processing is carried out to the text fragment containing every sample group so as to generate an entity relationship template; two target entities accord with the appointed relationship are extracted from the webpage text through the entity relationship template. According to the technical solution of the embodiment of the invention, the relationship between the entities can be automatically obtained; the obtaining efficiency of the relationship between the entities is improved; and the obtaining cost of the relationship between the entities is reduced.

Description

【Technical field】 [0001] The present invention relates to the technical field of Internet applications, in particular to a method and device for acquiring entity relationships. 【Background technique】 [0002] The knowledge graph mainly includes entities and the relationship between entities and entities, so obtaining the relationship between two entities is an essential step to construct and improve the knowledge graph. In the prior art, the relationship between some entities, such as the relationship between companies and the relationship between institutions, is important information in the knowledge graph related to the market. [0003] In the existing technology, the relationship between entities in the market-related knowledge graph is mainly obtained based on the co-occurrence data of entities. However, this method can only obtain the co-occurrence relationship between entities. If you want to accurately To obtain the real relationship between entities, it is necessar...
