Abstract

The invention provides an entity relationship extraction method and device, electronic equipment and a storage medium, and relates to the technical field of natural language processing. The method comprises the steps of obtaining a text of a to-be-extracted entity relationship, and processing the text through an entity and relationship joint extraction model to obtain a first entity relationship triple; determining words in the text and labels corresponding to the words, matching the words and the labels according to the relation rule set, and determining a second entity relation triple; constructing entity pairs according to the words and the labels, processing the text through a relationship classification model, and determining third entity relationship triples for the entity pairs; anddetermining an entity relationship extraction result according to the first entity relationship triad, the second entity relationship triad and the third entity relationship triad. According to the invention, the entity relationship extraction accuracy can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of natural language processing, and in particular, relates to an entity relationship extraction method, an entity relationship extraction device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In recent years, with the continuous development of information technology, a large amount of unstructured text data, such as press releases, has been generated. Unstructured data is not conducive to rapid analysis and processing. Information extraction studies how to extract structured data from these texts. Information extraction includes entity extraction and entity relationship extraction. Among them, entities refer to words with objective meaning or strong referentiality, including names of people, places, organizations, Time and date, proper nouns, etc. In related technologies, when extracting entity relationships, the accuracy is low. [0003] It should be ...
