Abstract

The invention is suitable for the technical field of artificial intelligence, and provides a data relationship extraction method and device, electronic equipment and a storage medium, and the method comprises the steps of obtaining a text sequence from a to-be-processed text, and obtaining a related dependent word of each word in the text sequence and a semantic relationship between each word andthe related dependent word based on a syntax dependency tree; generating a target word embedding vector corresponding to the to-be-processed text according to each word, the related dependent word ofeach word and the semantic relationship; and inputting the target word embedding vector into the deep convolutional neural network, performing entity relationship information extraction on the to-be-processed text based on the target word embedding vector, and obtaining a target entity relationship which is output by the deep convolutional network and has a set prediction probability value. The invention can be applied to a smart medical scene, the extraction convenience and accuracy of the entity relationship in the related information are improved, and the construction of a smart city is promoted.

Description

technical field

[0001] The present application belongs to the technical field of artificial intelligence, and in particular relates to a data relationship extraction method, device, electronic equipment and storage medium. Background technique

[0002] Information extraction refers to extracting various useful information from natural language processing texts, including but not limited to entities, relationships, events, etc. Among them, relationship extraction is a task in information extraction, which is mainly used to extract the relationship between entities.

[0003] In many fields, such as the medical field, there are a large number of texts, including various case records, medical experiment records, etc., which are full of various useful information, so an effective information extraction method is particularly important.

[0004] Under normal circumstances, when dealing with domain-oriented data such as medical data, most of the relationship extraction methods rel...
