The present invention discloses an entity relationship extraction method based on multiple languages and a server. The method comprises: among multiple languages, acquiring two entities between which a relationship is to be extracted and a first preset quantity of sentences related to the two entities in each language, and constructing a vector representation of each sentence related to the two entities; according to the vector representation of each sentence related to the two entities in a language and a vector representation of a preset relationship between the two entities, obtaining a comprehensive vector representation of each sentence related to the two entities in the language relative to any one language among the multiple languages; and according to each comprehensive vector representation and a pre-established relationship extraction model, extracting a relationship between the two entities from the preset relationship between the two entities. The server is used for implementing the method. The entity relationship extraction method based on multiple languages and the server that are provided by the present invention improve accuracy of extracting the relationship between two entities.
Description
technical field [0001] The invention relates to the technical field of information processing, in particular to a multilingual-based entity relationship extraction method and server. Background technique [0002] With the rapid development of society, we have entered the era of information explosion, and a large number of new entities and information are generated every day. As the most convenient information acquisition platform today, the Internet has increasingly urgent needs for effective information screening and induction. How to obtain valuable information from massive data has become a difficult problem. [0003] In order to store and process real-world knowledge in a structured way, people have established many large-scale knowledge graphs, such as Wikidata and Dbpedia. The knowledge icon represents all proper nouns and things such as people, place names, and organization names in the world as entities, and represents the internal connections between entities as re...
